Heckler & Koch MR762 A4 SBR 7.62 NATO 13" 10rd Rifle

The MR762 A4 SBR is Heckler & Koch's 7.62 NATO rifle cut down to a 13" barrel. It runs a short stroke gas piston rather than direct impingement, so combustion gas is never routed back into the receiver. The bolt carrier stays cleaner and cooler, and the rifle keeps running longer between cleanings. An adjustable gas regulator lets the system be tuned, which counts for more on a short barrel where port pressure runs high.

The rifle is finished in black, and the handguard is M-LOK, so lights, bipods and sling hardware mount directly wherever they are wanted. The 13" barrel is threaded at the muzzle, which leaves room for a suppressor or a different muzzle device, and the rifle comes with a 10 round magazine. At that length the MR762 A4 puts a full power 7.62 NATO cartridge in a rifle short enough to move easily through a vehicle or a doorway.
