Heckler & Koch HK416 internals video

This video shows the internals of the H&K HK416. One nifty feature is that the handguard screws were designed so that they could be unscrewed using the bolt lugs. The video is well worth watching.

Video was made by GunWebsites.

The civilian HK416 is expected to arrive next year.

Magpul AFG Review

[ I am pleased to present this review of the new Magpul AFG (Angled ForeGrip). The review was written by Isaac. ]

Let me preface this review by first establishing that anything to do with how your body interfaces with a weapon system will not be a review that’s binary in nature. There is no universal ‘this works’ or ‘this does not work’ as empirical facts on these types of products. What feels good to one person feels bad to another.

There’s been a rapid transition from vertical grips being used in the broom-handle sense, i.e hands fully around the column, and thus providing very little stability over the center axis of the rifle. So as the hand moves higher up along the line of the bore (in terms of grip) we’ve found that we need less tall of vertical grips to accomplish that need. A further variation on that is the idea of a hand-stop, which whittles away any unnecessary design to provide only a reference point for the hand to exert rearward pressure on.

The hand-stop concept is fantastic if you run a high tang grip. For me as a shooter I run my reaction side hand (or primary if working transitions) high, to the point where my knuckles are on top of the rail. The one issue that has been raised is the supination to the shooter’s wrist, or the over-extension caused by a hard 90-degree cant on the grip; the AFG works to solve this by using an angled gripping surface for the shooter.

Magpul AFG on Knights 11.5" SBR (Note angle of the wrist in relation to the AFG)

This review was compiled from the experiences of 3 shooters, myself, and two other experienced AR shooters who spent about 100+ rounds on each of my guns (11.5 Costa-style SBR, which is fitting for this test, and my KAC SR-15). Obviously the build quality is fantastic, it’s an affordably made, and well thought out product in terms of execution. The grip comes with two finger groove inserts, one in the A2 style nub, and one that’s smooth. I found for my hands the A2 groove interfered with my smaller hands, and I had to switch out to the flat profile insert (swappable within 1-2 minutes with only removing two screws to separate the AFG in half). The AFG mounts to the rail using a flat head screw and nut, to lock it in to the rail. The AFG takes up approximately the entire length of a standard 7” carbine rail. However you can position it further forward on the rail depending on what feels best for the shooter.

Knights Armament SR-15

So how does it feel? Well…I’d say it’s a mixed bag. My KAC SBR uses a KAC hand-stop, and the longer SR-15 uses a non-QD Tango Down Stubby vertical grip. Each gun has it’s own unique setup as I run two completely different light/laser rigs on each. So lets start with the SR-15 first. On the Knights SR-15 the combination of Surefire Scout, AN/PEQ-15, and Magpul AFG did not feel good for me at all. The previous setup (and keep in mind this is a combination of interactions on different parts) which used the TD Stubby allowed me to slightly extend my left thumb forward to activate the light, and when using the PEQ (pressure pad is directly under the PEQ-15, placed in between the left and top rail) all I have to do is a slight wrist rotation to hit the pressure switch. When the AFG is in place it’s a much more pronounced move to hit the light. And with the PEQ-15 instead of rotating my hand back a few degrees to allow my thumb access to the pad I now have to extend my whole hand out since it’s already canted. Simply put it’s comfortable when shooting, but it’s uncomfortable when trying to work with the light and laser. The AFG also interferes with rail-mounted accessories like Larue mounts. The AFG cannot slide next to them without the user removing part of the AFG with a Dremel. This isn’t a big issue and is user-solvable quickly, but it’s still an issue worth pointing out. Since the review I’ve switched back to the Stubby, and I’ll get back to that in my conclusions.

Magpul AFG used in combination light and laser (Surefire Scout, and Insight Technology AN/PEQ-15)

On the SBR the results were notably better. Because I run my Surefire at the 1 o’clock position this allowed me to better high grip on the AFG, and the results were comfortable, though not perfect. The 11.5” SBR also provides an interesting test bed. As my rifle is very similar to Chris Costa’s (I run a different light setup however) so it’s a situation where my rifle matches up very closely to those in the marketing material. So taking that in to account the biggest differences become the difference in body mechanics between the two shooters.

Magpul AFG on Knights 11.5" SBR

To summarize how the AFG feels, and all the shooters independently confirmed this after our demo (we all came to the same results separately) is that the AFG can be equated to a slippage in physical purchase (grip, not money). I equate it to sitting on your back, feet against the wall, as you push out with your feet you have a solid action/re-action to what you’re pushing against. The AFG feels more like pushing against an angled surface, in that the force is somewhat translated but the force also wants to go up and out. So while it accomplishes the job of pulling back it feels less positive in terms grip. The tango down grip provides a solid 90-degree point of reference for my hands and the hands of the shooters who demoed the AFG (and I can keep an extra 123A battery in the stubby). The same can be said of the KAC hand-stop. I will admit I like the AFG just a tiny bit more over the KAC hand-stop, which is why I’ll continue to use the AFG going forward. However I’ve found that the AFG for me at least was not the right choice for my longer SR-15. I understand the mentality behind the AFG, and I wouldn’t go so far as to say it’s a solution searching for a problem. As I said earlier this is not going to be a binary review, this is however going to be a binary product. You will either love it or hate it. My response to it on it being announced was very mixed bag, my response to it in use is still the same. The human body is absolutely unique among individuals; ergonomics is always about creating a compromise. It’s about making what feels good to the largest percentage of individuals. I’m in the percentage that just barely considers it an improvement.

However at 35 dollars it’s too cheap not to try out for yourself, make these decisions after some range time, and see how it works for yourself. I do want to thank Magpul for allowing me to try one of these out for free, and come to these conclusions myself as impartially as possible.

HERA 1911 Carbine Kit

HERA ARMS, makers of the Glock Carbine Kit, have turned their sights on the M1911 pistol. The Colt Pistol Extension (CPE) turns any mil-sepc 1911 into a .45 carbine.

Installation is simple. All that is involved is removing the grip panels and attaching the CPE in their place.

A stock adapter is available which allows AR-15 stocks to be attached.

In the United States this kit could be legally installed on any 1911 without violating BAFTE rules, as long as no stock or foregrip is attached. As soon as a stock or a foregrip is added, the gun must be registered with the BATFE.

The kit is featured in the current issue of DWJ magazine.

I do not know of any US distributors, but I am sure this will be picked up by US importers soon.

UPDATE: Video of it being used. Thanks to Gutao for the link.

UPDATE: Sven just told me that the 1911 used with the kit needs to be mil-spec. The DWJ magazine reported problems with non-mil-spec sights interfering with the kit.

[ Many thanks to Sven (Defense and Freedom) for emailing me the the info. ]

Vietnam manufactures M16 and M4 rifle clones!

I came across Imperial Defense, a British company, who manufacturer M16 and M4 clones.

mg 4a 6 tfb Vietnam manufactures M16 and M4 rifle clones! photo

According to this post at the MP.net forum, the guns are manufactured in Vietnam! This makes Vietnam the second communist country to manufacture M16s.

I would guess that the guns are copied off China's Norinco CQ 5.56 (M4A1 clone).

This is not the first time a Vietnam company has manufactured clones of Western weaponry. They notably manufacture a Lee Enfield clone, the AIA M-10, much to the frustration of American Lee Enfield enthusiats who cannot import the rifle due to BATFE rules which ban firearm imports from Vietnam.

Osprey Defense makes big claim

Issuing pressing a press release is one thing but actually selling to the Army or Marines is another! The press release, dated 15 December 2009, infers that their product can deliver 10,000 mean rounds between failure (emphasis added)...

SARASOTA, Fla., Dec. 15 /PRNewswire/ -- The 40-year-old problems of the M16 / AR15 / M4 rifle are now a thing of the past. In testing Osprey Defense, LLC has been able to install their OPS-416 system in under 4 minutes followed by firing more than 10,000 rounds without cleaning through an ordinary M16 rifle without failure. This is unprecedented from any firearm and even more amazing considering it requires no modification of the original gun.

Osprey Defense, LLC, www.GasPiston.com, a Florida based Limited Liability Company, has spent the last 3 years dedicated to developing a robust yet deceptively simple solution to the problem plaguing US Military's standard rifle platform. The M16 has historically been a less than reliable platform due to the deposits of hot gasses, carbon and debris in the critical operating areas of the rifle which cause malfunctions.

The Osprey Defense OPS-416 family of user installable gas-piston conversion systems is the solution to this problem. The company demonstrates it extensively on their website where you can watch demonstrations of the system being blasted with high-pressure sand which is enough to cut concrete, yet the rifle still runs. In another demonstration they buried a rifle using a 17-ton excavator, ground it into the earth, then dug it out caked with dirt, and the rifle still ran.

After millions of rounds of testing and an aggressive law enforcement agency and military Test and Evaluation program, the system is being made available today via their website and dealer/distributor network. New dealer opportunities are still available according to the company.

New US Army M16 “Tan” Magazine

I first mentioned the new "Tan" M16/M4 magazine back in June.

New and old, and older

The Program Executive Office (PEO) Soldier agency has just blogged about it ...

“With the improved magazines, we’re taking weapons reliability up another notch,” said LTC Chris Lehner, Product Manager Individual Weapons. “By incorporating a heavier, more corrosion resistant spring, along with a new follower design that does not tilt inside the casing, our engineers were able to develop a magazine that presents a round to the weapon with even greater stability. Increased magazine reliability results in overall improved weapon system performance.”

...

“Soldiers can remember it like this: ‘Tan – is the plan. Green – start to lean. Black – take it back,’” said LTC Lehner. “While the improved magazines increase reliability to an even greater degree, the new magazines by no means reduce the importance of Soldiers keeping their weapons clean and lubricated appropriately for the environment. Also, Soldiers must be proficient on conducting immediate action (SPORTS) if their weapon has a stoppage.”

Video of the new follower in action.

The Army has also developed a nifty tool to check if the feed lips are worn out. It is kind of a no-go gauge for magazines. If this does not already exist for civilians or law enforcement, I imagine it would be a popular accessory.

From MP.net ...

AGUSAN DEL SUR, PHILIPPINES - DECEMBER 12: Hostages of tribal gunmen are seen on December 12, 2009 in San Martin, Philippines. The suspected bandits, reported to be former government-armed militia led by Danilo 'Ondo' Perez, have abducted dozens of villagers, included schoolchildren and teachers, in the Southern Philippines.

I was surprised to see a polymer Thermold magazine being used by these bandits.

STANAG 4179 does not exist!

Most of you, I think, know what is meant by a term "STANAG magazine". For those of you who do not, it refers to a specification prepared by NATO which describes the dimensions of an AR-15 / M16 compatible magazine. An example of the usage of the term is in the Magpul's Masada spec document (emphasis added) ...

Multiple ammunition magazine capability is accomplished with unique lower receivers to accept either the NATO STANAG (USGI M-16) or the Automatic Kalashnikov (AK) magazine. Additional lowers receivers that accept other maga- zine types are also possible.

I received an interesting email from Roberto, a NATO employee, who explained that despite the term being commonly used, the specification does not exist. Apparently the draft STANAG 4179 was never ratified by member states and therefor it was discarded by default. If you call up the NATO Standardisation Agency (Bruxelles) and ask them for the STANAG 4179 document they will tell you that it does not exist.

This slide comes from a NATO presentation ...

So there you have it - STANAG 4179 does not exist! "USGI compatible" is a more correct term than "STANAG compatible" when referring to AR-15 magazines.

Many thanks to Roberto for this information.

New Magpul AFG (Angled ForeGrip)

The AFG (Angled ForeGrip) is a new forgrip from Magpul that will go on sale later this month. They claim it allows a more natural hold than a vertical foregrip.

afg 9 tfb New Magpul AFG (Angled ForeGrip)   photo

Drake, a Magpul employee, says ...

The AFG falls into the category of “Theory Based" products. Simply put, these products are designed to enhance weapon performance and user interface beyond what is currently available. Because these products do not simply replace an existing weapon component, there is an understanding with Theory Based Products that simple plug and play doesn’t apply. They require education by way of instructions, training, and familiarization with the product to become proficient, and only then will the benefits be realized. In addition to the AFG, other products in this category are the B.A.D. Lever, MS2, and ASAP.

The primary difference between the AFG and standard vertical foregrips is weapon controllability. This is a direct result of hand position, grip style and body mechanics. Below is a detailed description of the Theory behind the AFG.

Click on each slide to expand it.

Drake also says that it works well on AKs because the low profile does not hinder magazine change.

The AFG will be available in colors Black, Flat Dark Earth, OD Green and Foliage Green. The retail price will be $34.95.

Shotgun News test AR-15 magazines

Shotgun News magazine has published an AR-15 magazine torture test. The author, David M. Fortier, summarized the article on AR15.com ...

85footdroptest tango down pmagtapco tfb Shotgun News test AR 15 magazines photo
85 8.5 foot drop test. The Tango Down, PMAG and TAPCO all split down the spine.

Many more tests than these were performed. For the full write-up check out the Shotgun News article.

My thoughts:

PMAGs are very good, but not as indestructible as some think.

Aluminum mags are not as bad as some think.

You should consider checking out Lancer's mag.....they surprised me.

If MSARs mag dropped free they would be an interesting option.

Dropping mags onto cement is A LOT tougher on them then running them over with a SUV....

but all those videos from the various mag companies sure did work wonders for advertising didn't they.....

Many thanks to jdun1911 for emailing me the link.

UPDATE: The drop test was 8.5 feet, not 85 feet.
