To be fair I haven't used this a ton, but I have near a thousand rounds through it. I have been super impressed by its reliability. I have yet to have a single malfunction, which is amazing to me. It looks a little off compared to a standard AR up, b...

Piston reliability combined with super easy barrel swaps (either for caliber or length) as well as being an ambi upper (can setup ejection port for left or right side) make this a very versatile upp...

I picked up a new in box Arak-21 with 16inch .300 and .556 barrels at an estate sale recently and it has proven to be by far the best Semi-Automatic rifle I have ever owned. In reliability, recoil, and accuracy and it blows my Sig 556, Bushmaster A...

It does not fit properly (Requires hammering the lower pins into the upper in order to fit or filing in contact surfaces). In other words it's out of spec. Noticeable gap between the lower and upper after installation (If you somehow get those pins i...

Made really well, all metal parts finished well and tight clearances.
But, the spread at 50y is about 4” with a 6x scope (using standard m193 of a variety of manufacturers). Cool toy, not for real use.

The fact that you can have this become a bullpup alongside an A3 Industries Triad chasis system AND can shoot 7.62x39 pleases me to no end. Smooth operation, fine cycling, a stiff but solid gas block adjustment, and it shoots accurate enough to notic...

Features of Faxon Firearms ARAK-21 Upper Receivers:
- Fully machined from an aircraft grade 6061-T6 aluminum billet in a one piece design that incorporates a full length picatinny rail (Mil-STD-1913) on the top and three additional rails on the muzzle end of the receiver, making it a full M4 style quad rail upper. The top picatinny rail is laser engraved for optic placement.
- Charging handle is ambidextrous, non-reciprocating, foldable, spring returned and is easily relocated from left to right side without tools by the operator.
- Model ?39? Eight (8) lug bolt design with involute profile for both right and left hand versions. The extractor is positioned at 3 o?clock. This allows for a left hand version to use the same bolt by simply removing the cam pin and rotating 180 degrees and reinstalling the cam pin.
- Self-contained firing pin retention system enclosed in a rectangular bolt carrier that no longer requires a cotter pin.
- Bolted in hardened steel rail system for the bolt carrier to ride on. This allows a metal on metal wear surface for better wear characteristics and much smoother operation.
- Allows a folding stock to be added, as recoil system does not extend beyond the upper receiver to fully operate. Eliminates the noise and feel of the buffer tube cycling back and forth.
