MAX-11 mk2 Upper Receiver

This drop-in upper receiver converts your full auto M-11/9 into a match winning subgun. Features include a full length M1913 compatible rail on top and bottom. Hard mount points for additional M1913 rails on right and left sides. Contained within the upper receiver is a heavy weight bolt assembly that telescopes over the barrel. The bolt weight is securely attached to the bolt assembly with two hardened cap screws- no welds to crack or break. This reduces the rate of fire (ROF) from 1,100 RPM down to around 670 RPM. Easily shoot single, double or triple round bursts- just count them off while its firing, it's that slow and easy. Due to the reduced ROF, muzzle rise is reduced and multiple rounds stay on target. 670, 690, 770 and 950 RPM rates of fire available with the optional Variable Buffer System (VBS-3). Rate of fire is approximate and varies depending on ammunition used. Side cocking, reciprocating charging handle on left side. Designed for use with removeable AR-15/M-16/M-4 sights (not included), or can be used with just a scope installed. Comes complete with upper receiver, bolt assembly, cocking knob, barrel and manual. The MAX-11 mk2 attaches to the stock M-11/9 SMG lower receiver without any modification to the lower receiver.
