MFI (LONG) BARREL EXTENSION FOR AR15 Shorty PDW Pistols 922r Compliant, 9.375" Long to make a legal 16" Barrel.

MFI Adapter for SOCOM Style Fake Silencer (HK-94 / UZI Length) Fits 1/2 X 28 tpi Right Hand Threaded Barrels.

Also available for 300 Black Out with a 5/8 X 24 tpi thread. (See "Customize Your Item" above)

This page is ONLY for the ADAPTER / BARREL EXTENSION seen as "A" in the photo above.

You may also order (at an additional cost) the SOCOM Fake Silencer seen in the above photo that slides over the top of the ADAPTER via the "OPTIONS" tab.

NOTE: ETA on SOCOM Shrouds is at least 3 months away. This is why we do NOT have them on the option list.

The LAST PHOTO ABOVE is SOCOM Fake Silencer for HK94 / UZI Carbine (Marked "US GOV")

The "OPTIONS" tab gives you Special Discount.

This adapter is weapons grade steel. The length is 238.25mm / 9.375 inches, which if permanently attached will give you about 16.25" of barrel (assuming you have a 7.45" barrel). This added length will give you the much needed barrel length to make a 100% BATF legal rifle.

NOTE: Even though the overall length of this adapter is 9.375" part of that is the threads. As you can only count the threaded area once (threads in the adapter cover the threads on the barrel) the total ADDED LENGTH to any weapons system's barrel would be about 8.775".

NOTE TO SHORTEN: If you want to shorten the adapter / barrel extension you can do so by trimming down the rear end. The largest outer diameter measures about 0.750" in length and currently houses the threads. We can trim down the rear section any portion of the 0.750" (this is the past sticking out the back end of the SOCOM Outer Body in the photo above)and tap the next largest O.D. with the 1/2 X 28 threads for an added $15.00. Note that we do NOT re-plate or paint the trimmed area. If you are using the SOCOM can to cover the barrel extension you can NOT trim more of the rear or ANY of the front as those points are used to stabilize the outer can. If you are using the adapter WITHOUT the outer SOCOM Body then you could trim the front area as well.

If you do trim off the rear end completely... In order to allow the adapter to be completely hidden by the SOCOM Fake Silencer / Barrel Shroud we had to make the wall thickness very thin. Thus; Blind Pinning is NOT really an option. The thin wall lends itself to High Temperature Silver Soldering or you can weld a deep penetrating bead half way (minimum) around the circumference of the O.D. of the barrel / adapter.

So now you can turn your AR15 parts set or AR15 PDW Pistol into a legal semi rifle. This will fit any weapon with a 1/2 X 28 Right Hand Thread. The internal hole diameter that the bullet passes through is 0.468" in diameter. We made this large enough to keep the escaping gases from affecting the bullet trajectory. The larger hole size also helps keep the weight down. In the end this is much lighter than a long 16' barrel version. The weight of the product is only 5.2oz!

Total weight with the SOCOM Uzi / HK94 can is 15.2 oz.

We deliberately made this adapter / barrel extension out of steel so it can easily be to meet BATF permanently attached criteria. All NFA & BATF Rules apply.

Fake Silencers are also known as: Dummy Can, Faux Suppressor, Mock Silencer, Barrel Shroud & Non Functional Sound Suppressor.

No FFL needed, No Special License, No Permit Required & No Special Tax Stamp needed to order.

This accessory does NOT affect the accuracy of the weapon in any way.
