MasterPiece Arms Introduces the MPA .300 Norma Bolt Action Rifle

MPA answers the call of the long-range shooting community, introducing the up and coming .300 Norma to its stable of bolt action rifles.

Comer, Ga. (December 2017)MasterPiece Arms (MPA), manufacturers of the MPA BA Rifles and Chassis Systems,  is pleased to introduce the MPA .300 Norma Bolt Action Rifle. As the .300 Norma Mangum cartridge has begun to gain popularity among the long-range shooting community, MPA has answered the call with its newest bolt action rifle, providing 1/2″ MOA accuracy guaranteed. In 2016, the United States Special Operations Command (SOCO) selected the .300 Norma Magnum as their new Advanced Sniper Rifle Cartridge.

The MPA Tactical Chassis System is machined on MPA’s CNC Horizontal Machining Centers to exacting tolerances from 6061 aluminum. The v-bedding system provides additional clearance for glass bedding action and straight section of the barrel. The chassis also includes a built-in bubble level (inclinometer), thumb notch, front mounted bridge with upper Picatinny rail and lower mounted Picatinny rail. The new MPA Enhanced Vertical Grip is also included.

The MPA 300 Norma Bolt Action Rifle includes a precision gun drilled, reamed and honed Spencer / MPA rifle barrel made from 416RQ stainless steel. The hand lapped barrel is bore and land inspected on a video borescope. The chamber is indicated within 0.0001″ or less to the bore of the rifle. The Curtis Spiral Fluted One Piece Bolt with DLC coating is hand lapped and fitted to each individual action.                                                  

The MPA produced buttstock features an adjustable length of pull, adjustable cheek riser and monopod. The length of pull and cheek position are locked in place via a set of screws that are embedded into the buttstock body. It provides a very strong lockup of the cheek riser plate and recoil plate assembly. The included MPA Muzzle Brake is indicated on the CNC lathe for zero runout, ensuring long range accuracy.
