Benelli, not wanting to miss out, has entered the lucrative black rifle market with Benelli MR1 Carbine, a 5.56mm gas piston operated rifle.

Benelli MR1 Carbine

The MR1 Carbine is the civilian version of the Beretta Rx4 Storm (which never took off). Benelli, a subsidiary of Beretta, designed the ARGO gas system used by the MR1/Rx4 and manufactured both the MR1 and the Rx4 Storm.

What differentiates the MR1 from other 5.56mm rifles is the gas system it uses. Originally the Auto-Regulating Gas System (ARGO) was designed for the Benelli M4 Super 90, better known by its US Military designation, the M1014 Joint Service Combat Shotgun. Benelli then adapted the system for their ARGO line of hunting rifles (branded the R1 in the United States). In 2005 the Beretta Rx4 Storm, a tactical version of the ARGO rifle, was introduced and marketed to law enforcement. As far as I know the Rx4 has never been available in a select fire variant but they decided to market it to civilians as the Benelli MR1.

The ARGO gas system has an interesting short stroke piston design. Gas is trapped very close to the chamber. The high pressure gas ensures reliable cycling regardless of ammunition. This means that it can cycle any shotgun shells, regardless of the load. For a rifle it means the barrel can be very short and a suppressor could be fitted without any cycling issues. This gun is just asking to be converted into a Short Barreled Rifle!

The gas is then fed into an expansion chamber. The pressure in the chamber drives the piston assembly, which has dual rods. The high pressure is regulated by a release value. These diagrams should illustrate how the system works.

The receiver is made of aluminum, it is fully compatible with AR-15 magazines (including the 100 round drums) and, like all Benelli shotguns and rifles, the main spring is placed inside the butt stock - meaning a folding stock is not an option, although hopefully an M1014 folding stock will be made available.

MR1 Specifications:

Caliber: 5.56mm NATO / .223 Rem. Barrel: 16". Hard chrome lined. 1:9 twist. Rear Sights: Military-style Aperture Weight: 7.9 lbs.

The MSRP is $1299. I think they have priced it right. Although not cheap, and they can do better than the one five round magazine they ship with it, I doubt they could sell it much cheaper.

Extreme Shock have introduced a .223 Remington load called that the Short Ranged Tactical (SRT). It is very low powered producing just 745 ft. lbs. of muzzle energy, approximately 57% less energy than a 62 grain 5.56mm NATO round (SS109). This is about as much muzzle energy as a 10mm Auto round fired from a pistol.

Like all most of the Extreme Shock range, the bullets are made from compressed tungsten powder enclosed in a copper jacket. The round fragments when it hits a hard surface. As the name suggests this round is not intended for long range gun fights. It is a short range round suitable for self defense when over penetration of a standard 5.56mm or .223 Rem. round could have serious consequences. Extreme Shock says the round has enough energy to cycle a semi-automatic action.

The SRT’s 100 grain projectile is a frangible, lead-free design that will fragment on harder surfaces that would typically cause a lead-core bullet to ricochet. This projectile consists of a compressed tungsten powder core that is encased in a high quality copper jacket, with a special DuPont coating to reduce the velocity. This all works to produce lower recoil and minimize muzzle flash, thus enhancing the ability to acquire second shot placement faster.

The MSRP is $41.27 for a 20 rounds. Not at all cheap.

Ruger was that attractive girl at high school who you wanted to love but she stabbed you in the back and you just could not trust her again. That was two decades ago. Sturm, Ruger & Company CEO Michael O. Fifer has listened us, the customers, and changed the company culture for the better.

There is no better illustration for this change than the Evil Black Rifle itself which has just joined the Ruger product offering. The slogan for the SR-556 is "a platform redefined". I say it should be "a company redefined". I present to you the Ruger AR-15, the SR-556:

Ruger SR-556

Ok, I will wipe the tear from my eye, be a man and shove my emotional outburst back down where it came from Onto the features ...

The most significant feature is a new short stroke gas piston designed by Ruger. It shares the same benefits as other gas pistons system: a cleaner, cooler bolt carrier as the excess gas it vented out the gas block, far from the upper receiver. The AR-15 was not designed for a piston and retrofit piston systems can cause problems, for example the pressure from the piston operating rob can cause the bolt carrier to bind. It was been suggested that the Ruger bolt carrier is designed to mitigate this particular problem. Time will tell (I am no expert on this topic).

Disassembly of the gas system.

Another feature is a four position gas regulator. The first position prevents any gas entering the piston system. This turns the rifle into a single shot which requires the bolt to be manually cycled between shots. The next position allows the normal quantity of gas into the piston system to cycle the bolt. The next two position each let in more gas than the previous system which can help when the rifle is dirty or the ammunition is low powered. It is a compelling feature for reloaders because it gives them a greater range of adjustment for thier powder loads.

The rifle also features:

• Full length Troy Industries Quad Rail with rail covers.
• Hogue Pistol grip.
• Ruger branded Troy Industries flip up Backup Iron Sights (BUIS).
• Ships with three 30-round Magpul PMAG magazines.

The Specs:

Caliber: 5.56mm NATO / .223 Remington Barrel: 16.12" Barrel Twist: 1:9 Right Hand Weight: 7.92 lbs Total Length: 32.75" - 36" (depending on stock position) Stock: 6 position M4 style

It is nice to see Ruger has explicitly said .223 Remington AND 5.56mm NATO are compatible with the rifle.

The MSRP is $1,995. It is expensive and you could build one your self from parts for less, but if the gas system works flawlessly then I think it will be a good seller. I think it will sell for about $1800 on the street.

Here is the Ruger promotional video. They seem to be keen to promote it to law enforcement and military:

GunBlast.com made this video showing the rifle in action:

Thanks to y'all who emailed me about the SR-556. I appreciate it. Contrary to popular belief I am not dead just slow and overworked.

UPDATE: Many thanks to Brian for sending me these photos of his new Ruger SR-556.

Fore-end and gas regulator. The Backup Iron Sights. Nice touch with the buttstock Ruger logo.

This video shows a guy shooting a steel spinner target up close. He is hit by a ricocheted .223 bullet hitting him in the arm.

… he then goes on to show off the stitching kits he stole form the hospital / clinic that sewed his arm up.

Many thanks to Jay for emailing me the video.

Ryo decided his Remington 700 did not cut it, so he built a bolt action AR-15. Basically it is a AR-15 with a side charging handle and a blocked gas port.

Instead, I bought a 26″ Krieger AR-15 Varmatch barrel, with a 1:7.75 twist. They had these in stock, so it showed up at my apartment in about 2 weeks. To block the gas port, I simply installed the gas block off-centered (then later rotated it upside down because I was getting stung by gas and ejecta which managed to leak through the gas block and out the rear-facing hole where the gas tube would normally be).

A great looking rifle and I am sure it functions well and the bolt can probably be worked faster than many straight pull bolt actions.

Caliber: 9×19 mm and .45ACP (= 11.43×23mm)

This is the standard NATO caliber for pistols and a popular caliber for submachineguns. The only ones who seem to have a strong dislike for this caliber seem to be those U.S. Americans who continue to compare it with .45ACP.

The U.S. American problems with the 9×19mm caliber seem to include a mix of emotions (a Colt M1911 in .45ACP feels much more powerful) and poor quality of the U.S. standard issue 9mm pistols. The latter is as far as I know more a magazine production quality problem than a pistol design problem. The origin of .45ACP is said to lie in combat experience around 1900 in the Philippines where determined Philippinos weren’t stopped reliably by smaller revolver calibers. Tests on live animals in 1904 showed better effects for heavier bullets, but little improvement with velocity. Bullet design has improved a lot since then, and hollowpoint bullets that flatten their nose in soft tissue to increase their diameter are much more effective than simple soft lead bullets. A good 9mm bullet enjoys a similar advantage over a .45ACP soft lead bullet than the latter over a 9mm soft lead bullet. There’s a fundamental problem, though: There’s not much difference in effect on the target if you hit the wrong places and the permanent cavities of pistol bullets are all relatively small. Many body parts are simply not essential enough – their destruction doesn’t stop a determined opponent immediately; no matter whether you hit with .45ACP or 9×19mm.

Blackfork is trying to develop subsonic loads for his .223:

I looked on the Hogden site and found a subsonic load: 3.1 grains of Titegroup and a 55 grain bullet. I tried 3.1 grains of Titegroup under a Nosler 69. It works, doesn’t cycle the rifle but it’s quiet. The gun kind of rattles a bit when it goes off. Kind of a beefed up .22lr. About six inches under the zero for my normal ammo.

As he said, a problem is that a subsonic 55 grain has about the same muzzle energy as a High velocity .22 Long Rifle. On the other hand a heavy 77 grain bullet will not give great accuracy unless the correct barrel twist is used. The Shooting Times says a 1:8 twist rate is the minimum need to stabilize a 77 grain Sierra MatchKing.

I look forward to following BlackFork’s progress.

I try not to use words like “awesome” in the title for blog posts, so I substituted it with “game changing”. But don’t let that word change deceive you. I am *really* excited by this new stock coming out of Savage.

The Savage Accutrigger raised the bar on what consumers could realistically expect from a mass-produced factory trigger.Savage have brought custom-performance to factory-mass-produced stocks. They call it the AccuStock.

Savage explains the technology in their press release:

The AccuStock uses an aluminum spine and 3D Bedding Cradle molded into the stock in such a manner that it becomes an integral part of the composite stock.

The result is a polymer composite stock that possesses many of the same properties of high-end aftermarket stocks, bringing this high level of performance to the production rifle.

…

Rigidity – With its integral aluminum spine that runs from the action down the length of the forearm, the AccuStock is the most rigid factory polymer stock in the marketplace. No matter how hot the weather or the barrel, the forend stays rock-solid and the barrel remains free-floating.

Three-Dimensional Bedding Pressure – Pillar-bedded and v-block stocks, as good as they are, only apply bedding pressure on one axis, up and down. The AccuStock uses a wedge bolt to push the recoil lug back into the aluminum spine to prevent any movement forward and aft, while the bedding cradle literally squeezes the action from the sides when the action screws are tightened.

Initially two rifles will be available with the AccuStock:

Model 10 FCP

* AccuTrigger
* Proprietary Muzzle Brake (new from Savage)
* Detachable Box Magazine
* Oversized Bolt handle
* 24-inch heavy, fluted barrel
* Matte Finish
* Available in 308 Win. And 223 Rem.
* Left-hand models available

Model 10 Precision Carbine

* Camo: Digital Green Camo
* 20-in medium-contour barrel
* AccuTrigger
* Detachable Box Magazine
* Oversized Bolt Handle
* Matte Black Metal Finish
* Available in 308 Win. and 223 Rem.

Model 10 Precision Carbine

No word on pricing. Unfortunately it is not yet offering rimfire models.

It is lead free day here at The Firearm Blog*, this being the second lead-free ammo post!

Winchester has announced a new line of lead-free ammunition.

CCI currently manufactures lead free .22 Magnum called TNT GREEN but as far as I know Winchester are the first US manufacturer to announce lead free .22 LR. It is rumored that more companies will unveil their lead free rimfire at SHOT 2009.

The new Winchester SUPER-X .22 Long Rifle will propel a 30 grain THP (tin hollow point) at 1650 fps. This is a hot “hyper velocity” load which generates 181 foot pounds of energy, only slightly less powerful that the CCI Stinger at the muzzle.

It is likely that the case will be extended in length, like the CCI Stringer. The extended case can prevent the round from chambering in some rifles.

CCI Stinger length compared to standard .22LR (Wikipedia)

The new SUPER-X .22 Win. Mag (.22 Magnum / .22 WMR) pushes a 28 grain JHP at 2200 fps. The under 30 grain bullet means it will won’t perform as well as standard .22 Magnum 30 grain rounds.

SUPER-X .223 Rem lead-free pushes a 55 grain bullet at 3030 fps. Like the .22 Magnum, there is a significant performance hit. The round is being marketed as varmint cartridge..

This new range should be available in Spring 2009.

* That was a joke. I bought 100 rounds of “toxic” ammo today.

Hat Tip: Shooting Wire.

Good news, the civilian semi-automatic SCAR will be launched next year (2009).

Both versions will be available: the .223/5.56mm SCAR 16S (civilian equivalent of the SCAR-Light) and the .308/7.62×51mm (civilian equivalent of the SCAR-Heavy).

SCAR-Light carbine (14″ barrel). The civilian model will have a longer barrel.

I have emailed FNH USA for pricing details but they have not yet got back to me.

From the press release:

Experience the civilian-legal semi-auto only version of the rifle chosen by U.S. Special Operations Command as its first new rifle since the early 1960’s. The SCAR 16S is chambered in 5.56X45mm NATO (223 Rem.) while the SCAR 17S fires the 7.62X51mm NATO (308 Win.) cartridge. The innovative gas-operated, short stroke piston system reduces fouling for greater reliability. The side folding polymer stock is fully adjustable for comb height and length of pull and is colored authentic USSOCOM Flat Dark Earth. Both 10 and 30-round detachable box magazines(DBM) are available, and the ambidextrous operating controls instantly adapt the SCAR S-Series to any user.

Unfortunately they will not come with this …

UPDATE:
