Taking an essentially standard MR762A1 (caliber 7.62 x 51 mm NATO) semi- automatic rifle, Heckler & Koch USA turns it into a more effective precision rifle by an astute addition of the right optics and accessories. A Vortex Viper PSTII 3-15x44 FFP MRAD, HK G28 adjustable cheekpiece buttstock, and LaRue Tactical BRM-S bipod are the primary add-ons that make the MR762A1 Long Rifle Package (LRP) more than a sum of parts. Additional accessories and add-ons for the LRP variant of the MR762A1 include an ERGO Pistol Grip from Falcon Industries, the same Blue Force Gear sling used on the HK M27 IAR supplied to the USMC, and an OTIS cleaning kit. The rifle package, complete with one 20 and one 10-round magazine is shipped ready to use with the scope attached in a compact 42-inch Model 1720 Pelican case.
