This upper receiver converts your full auto M-11A1 or M-11/380 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 730 and 815 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.
Our patented Internal Recoil Mechanism allows installation of the Upper Receiver without modification to the lower receiver. It does not include an AR Stock Assembly, as it does not require it for operation. The MAX-11A1/15 IRM Upper can use any stock that will attach to the M-11A1 Lower Receiver. If you desire the AR Stock Assembly, it can be purchase seperately.
The photo above shows a MAX-11A1/15 with additional Lage Mfg. accessories that are not included with the MAX-11A1/15 upper receiver. Registered lower receiver and magazine are not included.

removable sights. Rail height is compatible with aftermarket AR Foregrips.

Shell Deflector
Deflects shells away from the shooter, especially helpful for left handed shooters. Being plastic, it also minimizes deformation of the ejected brass.
Magazine Release
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

Threaded 1/2-28 at muzzle end with jam nut and M16A1 style "Birdcage" flash suppressor attached.
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.

With extensive use, the handguard can get uncomfotably hot. We recommend you install M-LOK Rail Covers to insulate your hand from hand guard.
