MR762 A4 Pistol 13″

The 13-inch pistol configuration of the MR762 A4 in 7.62×51 — the larger-calibre member of the MR family, same short-stroke gas piston system.

A 13in barrel in 7.62 is a short, loud package. It buys manoeuvrability over the 16.5in rifle and gives up velocity for it.

Worth knowing: as a pistol configuration it has no stock, which is what separates it legally from the 13in SBR. Rules differ by state — confirm before ordering.

Parts note: MR556 and MR762 share some components — bolt catch sleeves, sear springs, forward assists — but barrels, buffers, gas blocks and magazines are caliber-specific. Browse upper receiver parts and lower receiver parts.
