MasterPiece Arms is best know for its semiautomatic rifles, pistols and suppressors. The company has just announced its first precision bolt action rifle, the MPA 308BA. The design is unique in that it is built around the Remington 700 bolt face and a Stiller’s Precision TAC Series action and a Spencer Precision barrel. MasterPiece Arms recently acquired Spencer Precision, and looking forward I’m sure we’ll see much more coming from that acquisition.
The MPA chassis is produced from 6061 aluminum with a v-bedding system that is matched perfectly to the Stiller’s TAC series actions providing zero twist or distortion. The stock is a Magpul PRS stock with a custom adaptor. The .308 also features a front mounted bridge with Picatinny rail and a lower mounted Picatinny rail, plus a 20 MOA scope rail. The body is finished in a durable medium texture powder coat or ceramic finish. The MPA .308BA is compatible with any AICS type magazines.
The Spencer/MPA barrel is produced from 416 (Condition T) stainless steel and is precision gun drilled, reamed and honed. It is pull-button rifled using CNC produced twist guides to exacting and consistent twist control and stress relieved in a Cress Vacuum Furnace. The barrel is available in a straight or helical fluting version.
The Stiller’s Precision TAC Series premium actions, produced solely for MPA, have a bolt-to-action fit of .0005″ or less. The action is machined from heat-treated stainless steel and the face, tenon and lug abutment cuts are machined in a single setup, ensuring exact parallelism and perpendicularity for critical features that affect accuracy. The Stiller’s Precision TAC Series bolt, also produced solely for MPA, is a one-piece design with the bolt, lugs and handle machined from a single piece of 4140 heat-treated steel and all critical features and dimensions are finished on a CNC OD grinder. All bolts feature spiral fluting and are hand-lapped and fitted individually to each action. The bolts have a nitride or armoloy finish. The MPA .308BA rifle is available with a counter twist muzzle brake and a jewel or Timney trigger. The MPA .308BA retails for an MSRP of $3,475.00 and includes the tactical chassis and an Accuracy International 5-round magazine. MasterPiece plans to release the MPA bolt action rifle in additional calibers.
