The Quad rail makes it look much more AR like.

Model 597 VTR Quad Rail

The Model 597 VTR Quad Rail features a free floating quad rail. MSRP is $590.

597 VTR A-TACS

The Model 597 VTR A-TACS is a standard VTR but with a A-TACS camo finish. MSRP is also $590.

Not pictured is the Model 597 VTR A2 model which, as the name suggests, features a standard AR-15 A2-style fixed stock. This has an MSRP os $445.

I am inspired!

They have not yet announced pricing.

The MPA22-T has a 5.25” threaded barrel with muzzle break, 1:16 barrel twist- RH and comes with a 30-round polymer magazine. It has 3.3 lbs trigger pull and a Parkerized finish. Because it was developed from the Mini 9mm frame, all available Mini 9 accessories will fit the MPA22T platform.

This new MAC is available in both the traditional top-cocker version (MPA22T-A) and as a side-cocker/scope mount version (MPA22SST-A).

I like this.

Why did I stuff ten rounds into a empty case? Some people measure case capacity in Milliliters, I prefer to measure it in Longrifles. For comparison a .338 Laupa has a capacity of 3 LRs.

I admit it is not the most accurate method of gauging case capacity

It turns out H&K had initially sued them over a long list of complaints. Most of these, the trade dress infringement being the sole exception, were thrown out of court. By simply making some design changes to avoid the GSG-5 being confused with the H&K MP5, ATI has been able to bring the gun back into the market under the GSG-522 name. The GSG-522 design was signed off by H&K and no royalties are required to be paid.

The GSG-522 has many subtle design changes. The biggest changes are ...

• Textured pistol grip
• Redesigned selector switch
• Picatinny rail on top
• Square "open" front sight rather than the classic H&K ring front sight.
• Integrated sling bracket (on trigger guard ... looks a bit flimsy to me)

New GSG-522 Pistol (bottom) compared to original GSG-5 PK Pistol

Close up of the new sight.

It still retains the MP5 style but is much less likely to mistaken for a real MP5 (although in reality the original GSG-5 would also not have been confused with the real deal).

The joke is that ATI will offer "upgrade" kits that will allow you to retrofit a GSG-522 to look like the original GSG-5.

GSG-522 Pistol and SD Carbine (with 110 round drum!!!)

The GSG-522 will be available in many configurations:

• GSG-522 Carbine with 16.25" barrel
• GSG-522 SD Carbine with 16.25" barrel (MP5-SD style)
• GSG-522 Pistol with 9" barrel
• GSG-522PK Pistol (MP5K style) with 4.25" barrel

The carbines will be available in black, nickel and camo finish. Each model will ship with either a 10 round or 22 round magazine.

One of the coolest features of the new GSG-522 line is the 110 round drum magazine.

The drum does not need to be wound. This is a plus, although I imagine after 75 rounds your fingers are going to be very tired (a mag loader is not yet available). An adapter will be offered at a later time which will allow the magazine to be used with the ATI GSG Kalashnikov.

As soon as this drum goes on sale you can be sure that in no time Youtube will be filled with videos of people dumping 100 rounds as quickly as possible

I do not yet have pricing info for the drum or GSG-5 firearms.

GSG-522PK

Introduced in Italy in 2004, the Beretta U22 Neos Carbine Kit has finally made its way stateside.

The kit includes a 16" barrel (1:16 twist), forend, stock (which replaces pistol grip), weaver rail, adjustable aperture rear sight and TruGlo front sight. No gunsmithing is needed to install it.

The Kit will retail for about $280. Not cheap!

Obviously this device is very impractical in the real world. The bright green light shining into the user face would make the sights very hard to use at night, not to mention making the user an easy target.

So just to summarize all the point about the Glock Gen4 ...

• Initially Glock 17 (9mm) and Glock 22 (.40 S&W) will be available. Compact models will follow later in 2010.
• Features duel recoil spring which should increase reliability.
• Features Swappable backstraps.
• Magazine release swappable between left and right.
• Old magazines still work, but only when mag release is on left side.
• Gen4 slide is clearly marked as "Gen4".
• Retail price for G17 and G22 Gen4 is about $700 (actual prices will be lower than this).
• Glock will cease sales of the 3rd Generation and RTF models.

[Hat Tip: Pistol Training]

Taurus USA import many of thier guns from their Brazilian parent company. Because the BATFE has rules regarding size of imported guns, the company imports the Mod 94 .22 LR revolver with 3" barrels and cuts them down to 2". This funky revolver is a fully functional factory error.

It is being sold by Ocala Armory for $500.

Umarex is manufacturing this .22 LR rifle patterned on the HK416¹ . It features ...

• Metal receivers.
• Functional dust cover.
• Full length picatinny rail.
• Adjustable stock.
• H&K style diopter iron sights. Adjustable for elevation or windage.
• 16" barrel.
• Pistol grip with compartment (for spare batteries, tools, etc.)

The rifle will be sold with either a 10 or 20 round magazine but 30 round mags will be available for purchase.

The previous Umarex .22 rifle, the Colt M4, had some serious problems. Justin Biddle, Umarex's Marketing Manager, assured me that they have been made changes to the Umarex action and sorted out the issues experienced by the M4 owners.

Hat Tip: On Point Supply

.22LR is by far the most popular consumer cartridge. Every .22LR shooter with a silencer, and many without, would love to be able to buy reliable and accurate 60gr+ bullets, as well as threaded barrels with sufficient twist rates to stabilize them.

So my open question to the firearms industry is: Where are the reputable bullet manufacturers selling cases of plinking, varmint, and match-grade 60gr .22LR ammunition? And where in the vast marketplace of .22LR guns and parts are the 1:12 twist .22LR barrels with threaded muzzles to shoot those bullets?

Aguila 60 grain SSS Sniper Subsonic. Image from MidwayUSA

I think your only options right now are the Aguila 60 grain SSS Sniper Subsonic and, if you want anything resembling accuracy, a Volquartsen barrel for the Ruger 10/22. I imagine a lot of work would needed to be done on the 10/22 action to ensure if would cycle.

"bronco" developed a conversion kit which allows a standard AR-15 pistol grip and stock to be attached to the AR-7 receiver. A forum posting over at the Predator Wild forum seems to suggest he may be willing to sell these kits.

Rezolution Tactical

The CNC machined receiver features a full length monolithic top picatinny rail. A bottom rail and side rails are bolted onto the receiver. Internally it makes use of a Ruger 10/22 compatible bolt, trigger group, magazines and v-block barrel mounting system. Rimfire Technologies, a well known supplied of after market 10/22 parts, supplies many of the internal parts, including the barrel.

Precision model with bull barrel.

As most of you have already guessed, the Rezolution is compatible with standard AR-15 stocks. What is slightly disappointing is that it is not compatible with AR-15 pistol grips, although this is a minor fault.

The pricing starts at $941.81 for the R-RT-21BL (Rezolution Tactical with 21" length receiver). This model features a 16" .750 diameter fluted stainless threaded barrel with AR-15 A2 flash-hider and a M4 style stock.

Production has only just begun and some models will not be available until next month. I personally think these guns are a very good deal and are going to sell very well.

This design uses your existing upper receiver and cocking knob with a drop-in barrel insert, bolt assembly, magazine adapter and modified UZI .22 LR magazines. The magazine inserts in the pistol grip mag' housing just like the original 9mm magazine.

LAGE currently manufacture a range of slow-fire upper receivers for M-11, M-10/9 (a version for the M-11A1 is in development). These uppers slow the rate of fire from 1100 RPM to 600 RPM, making the gun much more controllable.

These guns are well known for eating through ammunition with their very fast rate of fire. The cost of these uppers are around $760.

Heckler and Koch is suing German Sports Guns and American Tactical Imports over trade dress infringements. Seems they don’t like GSG making a 22LR version of their MP5.

These cases, like when Colt sued H&K over the 416, are counter productive to the industry in general. It seems bizarre that a firm, which is a subsidiary of a German company, is suing the importers of a German made gun. They must not be able to sue for it in Germany court.

I know nothing about "trade dress infringement", but I do know that those fanciful concepts of "common sense" and "justice" have long been forgotten in intellectual property court, thanks to the efforts of Disney Corp's hard working lawyers and lobbyists.

I recently reported that H&K has licensed the production of .22 rifles patterned after the MP5, MP7 and other H&K firearms to Umarex. No doubt this is the reason they have taken legal action against ATI.

UPDATE: H&K and ATI settled. GSG-5 sales will cease.

Ruger 10/22 VLEH Target Tactical Rifle

The 10/22 VLEH¹ features a Hogue OverMolded stock, in my opinion the best for the Ruger 10/22. The barrel is 16" heavy .920" profile match-grade barrel with target crown. It has the same trigger group as the Ruger 10/22T, which is much superior to the standard factory trigger. To top it all off, a bipod is included.

The VLEH configuration is almost identical to my favorite 10/22 configuration. It makes perfect sense for hunting and general plinking. My only complaint would be the lack of iron sights, although few people will miss them.

The market for this pistol, and its not-yet-on-sale competitors the GSG 1911, are 1911 shooters who want to practice with cheap ammunition but would rather have a dedicated gun than purchasing a .22 conversion kit and having to swap it in and out of their .45 1911.

The F88T Austeyr

Note the subcaliber magazine insert - the only giveaway that it is chambered in .22 LR

Almost no information about this rifle is available online. This is very surprising because the rifle is currently in service with a major defense force.

The F88T Austeyr was developed by ADI Limited (now known as Thales Australia). It is, as far as I know, the only variant of the Steyr AUG chambered in .22 Long rifle. A page on the, now offline, ADI website described the weapon as:

ADI has developed a .22 calibre training rifle for use by the Australian Army. The weapon provides an economical training alternative, with very low ammunition cost, which can be used in environmentally sensitive training areas and indoor areas for special force training with reduced risk to trainees and instructors.

This paragraph sums up just about all the information available online! Because of the lack of information I was convinced that very few of these had ever been built, but I stumbled across the minutes of a meeting from an Australian Air Force conference where they discussed an order of 200 F88T's which were going to be used for cadet training. Presumably there are more than 200 in existence.

Australian cadets also train with .22 single shot bolt actions rifles.

I do not have any technical information about the gun. Most .22 semi-automatics share similar features. The gas system will be non-functional because a .22 LR cannot generate enough case to cycle an action. The action will be a standard blowback system. The barrel is probably the same as the regular Austeyr. While this is not optimal for accuracy I can't imagine it would have been worth the cost of producing dedicated .22 Long Rifle barrels.

I am sure that the owners of the civilian Steyr AUG SA, which went on sale this year, would love to have a .22LR conversion kit. Realistically, a third-party American firm is much more likely to develop a conversion kit than Steyr is too either develop their own or license the design from Thales Australia.

Ruger SR-22

Jeff Quinn holds a tricked out SR-22

You are probably thinking that the action in the above rifle does not look much like a Ruger 10/22. This is because a standard Ruger 10/22 action and trigger group sits inside a Nordic Components designed conversion chassis / enclosure.

Nordic Components Stock Kit - very similar to the SR-22 rifle.

The chassis allows a standard AR-15 stock and pistol grip to be used on the rifle. It also allows a standard Ruger 10/22 barrel, which attaches to a v-Block, to be used with a the AR-15 style handguard. This breakdown photo illustrates how it all fits together:

The mid length handguard is drilled and tapped to allow picatinny rails to be installed on the 3,6,9 and 12 o' clock positions, if desired. These rails allow all standard AR-15 accessories to be used with the rifle.

Ruger 3" SR-22 TR 3 Picatinny Rail ($14.95)

SR-22 Full Length Picatinny Rail ($39.95)

Another benefit of the SR-22 over a standard 10/22 is that the barrel is factory threaded and a Ruger SR-556 / Mini-14 flash suppressor is installed.

The Ruger press release:

Sturm, Ruger & Company, Inc. (NYSE-RGR) announces the introduction of the Ruger® SR-22™ Rifle, an autoloading, rimfire rifle that combines the legendary reliability of the Ruger® 10/22® with the ergonomics and configurability of the new AR-style Ruger SR-556™. The new SR-22 Rifle allows shooters to use economical .22 LR ammunition, while still enjoying the look and feel of an "AR" and experiencing the reliability they have come to appreciate from Ruger.

Because it utilizes the unique rotary magazine supplied with the Ruger 10/22, the SR-22 Rifle offers the same gold standard for reliability in autoloading rimfire rifles. Like the 10/22, the AR-style SR-22 Rifle also has an extensive array of accessories available, allowing shooters to select a custom configuration that best suits their tastes and needs.

The SR-22 Rifle uses a standard 10/22 action inside a top-quality, all-aluminum chassis that faithfully replicates the AR-platform dimensions between the sighting plane, buttstock height, and grip. The SR-22 Rifle provides a Picatinny rail optic mount, and includes a six-position, telescoping M4-style buttstock (on a Mil-Spec diameter tube), plus a Hogue® Monogrip® pistol grip. Buttstocks and grips may be swapped out for any AR-style compatible option.

The SR-22 Rifle also features a round, mid-length handguard mounted on a standard-thread AR-style barrel nut. Picatinny rails, specifically designed for this handguard, are available from Ruger, allowing the handguard to be configured to accept any number of rail-mounted sights or accessories. A barrel support block is installed in the handguard, ensuring accuracy and allowing the standard 10/22 V-block barrel attachment system to be used.

The SR-22 Rifle is equipped with a precision-rifled, cold hammer-forged alloy steel barrel. The 16-1/8" barrel is capped with an SR-556/Mini-14 flash suppressor mounted with a 1/2"-28 thread.

Ruger advertisement for SR-22:

Michael Bane has also created a video review over at the Down Range TV Blog. Michael hinted at the rifle earlier this week, but I must admit I did not imagine a tactical Ruger 10/22 was what Ruger had in store for us!

Looks like a lot of fun!

A parts list and computer code to build a similar system can be found at Waterloo Labs.

Many thanks to Antonio for the link.

UPDATE: Nookyon points out in the comments that the game appears to be a flash based “remake” of Half Life, not the original.

When they release more information I will be sure to publish it on the blog.

The device has three vertical “barrels” which are loaded with blackpowder. A shotgun primer is inserted into the side of the barrel. The shooter aims at a hole in the front steel plating. Through the hole is a steel plunger that ignites the primer. The result is a big bang and lots of smoke.

It looks like a lot of fun and only costs 25c per target (according to the manufactures website. I do not reload. ). That even cheaper than the poor-mans-reactive-target (pool chalk).

More info at Target Cannon.

It has been made compliant by fixing the stock so it cannot be adjusted and supplying a 10 round magazine. The MSRP is still $499.

The pistol grip and removable magazine prevent it from being California compliant. .22 Rifles are exempt from California Assault Weapon laws.

The new Hyper Speed HP load is a very hot load that matches the ballistic characteristics of the CCI Velocitor round. The Hyper Speed HP, like the Velocitor, features a copper plated 40 grain hollow point bullet. The bullet has a published velocity of 1435 fps at the muzzle, which works out to be 183 ft-lbs of muzzle energy.

A significant difference between the CCI load is that is will be sold in a 100 round box, rather than the CCI 50-round box. This suggests it may be quite a lot cheaper that the Velocitor. If it is, I will defiantly consider switching to this for my hyper velocity needs.

Winchester are also introducing a 555 round bulk pack, giving it a slight edge quantity wise over the Federal 525 and 550 bulk packs.

The bulk pack features high velocity (36 grain / 1280 fps) rounds with copper plated hollow point bullets. Nothing fancy.

Overall I am quite impressed with the new offerings from Winchester. I don’t think there is much else they can do as far as rimfire ammunition is concerned.

The “Model 597 VTR 22LR with Collapsible Stock” features a Pardus collapsible stock and had an MSRP of $445.

UPDATE: According to John, Product Development manager, different AR stocks should be compatible. AR pistol grip interchange will be limited because of the receiver design.

Thanks to Linda from Remington for her help getting me information.

From the press release:

The heart of gas piston technology is its use of nitrogen as the power, instead of a coiled steel spring.

Unlike steel and CO2, nitrogen isn’t adversely affected by temperature. In addition, the technology allows for much easier cocking. The nitro piston starts engaging the moment the shooter starts cocking the gun. Gas pistons can also be left cocked for long periods of time without degrading and losing velocity, the way steel springs do. Also, when a steel spring uncoils, the vibration is not only annoying, it compromises precision. “Nitro Piston technology solves both by creating a smoother cocking force and releasing the gun’s power more quickly,” said D’Arcy.

The new rifles will not be available until June, but Pyramyd Air have them available for pre-order. They claim the piston system produces a lot less noise (most of the noise from a break barrel airgun is the piston), less recoil, easier cocking and long lasting.

They are available for pre order for $324.99. They comes in .22 and .177 versions (1000 fp/s and 1200 fp/s respectively) and either either a black synthetic or digital camo thumbhole stock. They all feature a bull barrel and two stage trigger.

Air gun expert and blogger Tom Gaylord was involved in the development of the system. If he was involved it must be good! I don’t think he would risk his reputation on an inferior product.

Two models are available, synthetic or wood, with either with 10 or 24 round magazine. They have an overall length of 34.5″ (an inch longer than the original wood stocked Russian AK-47) and a barrel length of 16.5″. Click to expand the photos:

Synthetic model.


Wooden model 24 round magazine.


Wooden model 10 round magazine.

It was rumored that the wooden stock would be wood-looking plastic, but it is real, and looks really nice. The gas system is defiantly fake, it is a blowback operated rifle that requires high velocity .22 ammunition to cycle. You can see in the above photo that the 10 round magazine has the same AK-like size as the 24 round magazine, which is a nice touch. It appears to be compatible with the AK side mount for optics.

The MSRP is $549 for the synthetic model and $569 for the wood. I think this will be very popular rifle.

What is really cool is how the gun came into existence. Chris from ATI told me that last year after the original GSG-5 was introduced they noticed many people on the ar15.com GSG forum voiding their warranty to achieve the SD look. Late last year they flew to the GSG HQ in Germany to discuss these modifications. They worked out a plan.

This is a fantastic example of a company listening to it’s customers. I wish more gun companies would do this.
