The ENDO Tactical Stock Adapter Glock Edition (TSA-G) is an adapter that allows any AR-15 / M16 compatible stock to be attached to a Glock pistol.

Glock with Magpul UBR stock, 33 round magazine and sling.

The adapter can be easily attached and removed in about 30 seconds. The benefits of such a system are numerous. Even with the stock attached it is small enough to be carried concealed under a jacket – unlike a rifle or carbine. The stock improves accuracy by steadying the pistol against the shoulder. This also helps soak up recoil allowing faster followup shots.

The downside of such a system, for civilians, is that any pistol it is used with must first be registered as a Short Barreled Rifle (SBR) with the BATFE. I am no expert, so don’t quote me, but my understanding is that carrying an SBR concealed, even without the stock, would not be allowed with a CCW permit in many, or all, states.

Another downside is the total cost of the weapon system. If we assume a new Glock 17 costs $500, then add $200 for the ATF stamp, $154.99 for the ENDO stock adapter and $60 for a Magpul MOE Carbine Stock, we get a total cost of 914.99! This is a lot more than a 9mm carbine such as the $400 Kel-Tec SUB-2000.

Cost aside, I really like the system. I don’t think there will be a shortage of enthusiasts who will be willing to pay. I expect ENDO will be marketing this heavily to Law Enforcement Organizations who carry Glock pistols.

The system is compatible with the G17, G22, G24, G31, G34, G35 and G18 (including the L, C and RTF versions).

On a side note, I am surprised by the attachment mechanism. A steel detent pin must be manually pushed through the pistol backstrap. Compared to the system used by the FAB Defense (Israel) stock which clips in, it takes longer to install and is more of a fiddle. I wonder if the clip system is patented.

A big thanks to Kevin for links and information.

SayUncle spotted this ad for a SIG 556 Short Barreled Rifle. What is very interesting is that the rifles being sold by Manchester Firing Line are factory manufactured, not conversions of the standard rifles.

SIG 556 Short Barreled Rifle

Although the price is steep at $3,495, Sig 556 Reviews notes that SBRs conversions are popular with the Sig crowd:

The P556 has definitely been popular with the SBR crowd so its good too see that Sig Sauer is paying attention and grabbing some of this pie by jumping into the NFA market. There have been a few post’s on the SigArms556 forum about people with P556 SBR’s that have had customer service issues (Sig basically coming back saying theiy voided they’re warranty)

Gun writer and SBR enthusiast Bob Boyd is currently building his own Sig SBR and modeling it after the Sig 552 Commando Carbine. The Commando is probably better classified as a PDW (Personal Defense Weapon), than a Short Barrel Rifle.

I am looking forward to seeing Bob’s rifle when it is completed.

I have never seen such an ornate AK-47 before.
I would be embarrassed to go to the range with it.

I think the bling on this one is fake


I am sure the saints do not protect gangsters.

Robarms will be making a PDW (personal defense weapon) version of their XCR rifle. The PDW has a shortened stock and a 9″ barrel. From the videos it looks like it will be available with either a fully automatic trigger group, for those who can buy such things legally, and a semi-automatic trigger group for the rest of us.

So far they have a 5.56mm NATO and 7.62×39mm model.

Compare the sound and recoil of the 5.56 and 7.62 models in these videos:

A very sexy firearm that will be available in July. This video shows a 5.56mm semi-automatic model being shot:

Also from Robarms is a new two stage trigger for the XCR called the Enhanced Trigger.

This trigger is two-stage with a 3.5 pound pull. We’re calling it an “Enhanced Trigger” rather than a match trigger for several reasons. First, match triggers usually have very small tight control surfaces and/or small screws or springs that cannot hold up under tough use. Our Enhanced Trigger is a very light two-stage trigger that is very controllable whether shooting paper at a distance or at moving targets. We are taking orders for the Enhanced Trigger now. The parts consist of a a new trigger, hammer, and disconnect. They can be added to existing XCRs without modification to the rifle.

UPDATE: 6.8 SPC is now also offered. Two models are available: the Mini (9″ barrel) and Micro (7.5″ barrel). The basic models cost $1500.

Like with anything else BATFE, registering a Short Barreled Rifle takes a lot of time, patience and paperwork. Bob Boyd has been going through the process himself and has blogged about the process, along with links to all the requisite forms

Before beginning, I urge everyone to check their state and local laws to make sure you’re in compliance with all regulations.

The process is more time-consuming and aggravating than difficult. Regardless, you must have a BATFE-approved Form 1 in your possession prior to attaching the stock. To accomplish this, you’ll need the following:

Canadian gun dealers are importing the civilian version of the Norinco CQ 5.56mm Type A, a clone of the Colt M4. It pretty much a straight clone of the M4A1, complete with 14.5″ barrel, the biggest difference being that the civilian version that is being imported is semi-automatic only.

The rifle seems to be well received by Canadian shooters, although the finish is said be be poor. Of the Norinco manufactured firearms I have seen, they tend to be poorly finished. The badly scratched finish can be seen in this photo:

This video shows the firearm being used (iron sights and Magpul stock has been installed):

LeverArms.com are selling it for C$899.00, which seems like a good price for a M4 clone, although I am not sure what M4 AR-15s normally sell for in Canada. Canada is likely the only country where it is being sold to civilians.

Thanks to Dennis for information about the rifle.

The KRISS .45 submachine-style gun is now available in a Short Barrel Rifle (SBR) configuration (I say submachine-style because the civilian version is semi-automatic). The SRB/SO features a 5.5″ barrel and weight 5.6 lbs when unloaded.

The Vector is fed from Glock 21 magazines.

You were warned … This is the Frankenstein’s monster of early 20th Century American arms:

An M103 Springfield in an SBR (Short Barrel Rifle) configuration presumably converted to .45 ACP with a 1911 pistol grip being used as the magazine well.

It is hideous. Something only its mother could love!

Travis of Magpul put together a very cool AK/Saiga. Click to expand the photos:

Two charging handles. Handles from Bushmaster ACR/Masada

-It is a Saiga cut to 12″ and threaded 1/2 28 right in front of the Russian threads and SBRed with a AAC M42000

-The charging system is something I came up with about 2 years ago before all the other ones you see out there. As you can see from the left side the dust cover is not as open. Yes those are ACR charging handles that I cut and welded on to the carrier.
They do reciprocate which it seems some people have a problem with… why I haven’t a clue… its an AK?!

-Extended custom trigger finger Mag release and Safety

-Ace MIAD grip adapter

-CTR with cheek riser.

-Ultimak scout and lower rail (I welded the locking tabs in for a tighter fit.)

-Aimpoint T-1

-I drilled and tapped the Pig nose adaptor for a sling stud for the MS2 Sling.

-As for the Ranger plates I just took PMAG plates and mashed them on and modified the tab to fit. they will stay on even you don’t mod the tab.

Since this is a one of a kind AK we have deemed it the MAG-K

Very nice. Travis made this clear it is a once off project not a production rifle.

These photos are of a new Saiga 12 build. They were too pretty not to post.

I really have got to get myself a Saiga 12.

This SRB from Spike’s Tactical looks very cool and I bet it is a lot of fun to shoot.

This photo shows the $180 folding stock upgrade.

The .22 ST15 features:

* A3 flat top
* 6″ 1×16 twist barrel
* ST-15 mil spec lower
* YHM mini rail free float handguard
* Spike’s fake SD can
* Spike’s .22lr bolt, 6 position M4 stock with mil spec tube and Black Dog full size mag.

It is a pity the suppressor is fake.

Zak has written a very interesting article on “Fighting Optics for the AR-15″. He focuses on M4 type rifles and SBRs (Short barreled rifles).

Now that optics have come of age on fighting rifles, one of the most compelling reasons to have a longer barrel has been removed. With iron sights such as those on the M16A2, practical accuracy depends on sight radius; it is easier to shoot accurately with more distance between the front and rear sight. Optical sights have no sight radius; barrel or weapon length is now separated from the ability to obtain a precise sight picture. This change allows a 14.5-inch M4 to have the same sighting precision as a 20-inch M16A2 or even sniper rifle.
