Status: Out of Stock – Please Call for Backorder Waiting List

This Chester County Armory listing is for a new condition Lage MAX-10/15 Conversion Upper in 5.56mm NATO for a MAC M10/45 or M10/9 Sub Machine Gun.



From Lage Manufacturing:

This upper receiver converts your full auto M-10/45 or M-10/9 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 790 and 950 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-10/15 IRM Upper can use any stock that will attach to the M-10 Lower Receiver. If you desire the AR Stock Assembly, it can be purchase separately.
