FAQ

Is a lower receiver included?

No. This is an upper assembly only; the lower receiver, magazine and sights are not included.

What lower does it fit?

A dedicated pistol-caliber AR lower, such as a Glock-pattern lower using 9mm Glock-style magazines. A standard AR-15 lower with 5.56 magazines will not feed it.

How does it operate?

It is a direct blowback system, so it has no gas tube. A heavy PCC buffer is used for reliable cycling.
