This upper receiver converts your full auto M-11/9 into a rifle caliber machinegun. It is chambered in 5.56 x 45mm but it is also compatible with .223 Remington ammunition.
Rate of fire is between 650 and 900 RPM, depending on ammunition used and the gas setting of the Odin Works adjustable gas block.
Full length Picatinny rail on the top is the same height as an AR-15 flat top upper so standard AR foregrips with a rail on top are compatible.
The upper features a side charging, non-reciprocating, spring return charging handle on the left side.
A plastic shell deflector is fitted to provide comfortable shooting when operating left handed. Being plastic, it also minimizes deformation of the ejected brass.
A Troy Ambidextrous Magazine Release is provided to allow easy mag' changes with your left hand.
Barrel mounting is AR compatible so different AR barrels and handguard mounts can be used, including the original AR delta ring and barrel nut.
Available with two different recoil sytems, the Internal Recoil Mechanism (IRM) and the AR Recoil Mechanism (ARRM).
The ARRM version requires a 5/16" (.312") diameter hole to be drilled through the rear sight plate. Using this version will allow you to experiment with different AR Buffers and Springs and customize performance. The ARRM includes a Stock Assembly that consists of a Stock Adapter, End Plate, Buffer Tube, Castle Nut, Carbine Buffer, Custom AR 15 Recoil Spring and Magpul MOE Stock.

Side cocking, non-reciprocating, spring return charging handle located on left side.
Deflects shells away from the shooter, especially helpful for left handed shooters. Being plastic, it also minimizes deformation of the ejected brass.
The magazine release is a Troy Industries ambidextrous release. This makes magazine release with the left hand easier by just grabbing the magazine and using your thumb to swipe the magazine release lever on the left side of the gun. A standard magazine release button is located on the right side.
Rear gas seal
The upper is fitted with a rubber gas seal at the top rear to prevent smoke and debris from being directed towards your face when firing with a sound suppressor.
The upper is designed to be compatible with Adams Arms Piston kits, and possibly others. The upper receiver will accept the pressed in steel bushing.
Bolt Carrier Group

Adjustable Gas Block
An Odin Works adjustable gas block is installed on the barrel. This allows the gas system to be tuned to your specific ammunution to allow softer recoil and a lower rate of fire.
