MPA Rolls Out 6mmBA and 6.5mmBA Bolt Action Rifles


MasterPiece Arms (MPA), manufacturers of the MPA MAC Line of semi-auto pistols, carbines, suppressors and MPAR Rifles, is now producing bolt-action rifles in 6mm and 6.5mm calibers.

The MPA 6mmBA Bolt Action Rifle and the MPA6.5mmBA Bolt Action Rifle are built on an MPA tactical aluminum chassis with a Stillers Precision TAC Series action and MPA/Spencer hand-lapped barrel.

The MPA chassis is produced from 6061 aluminum with a v-bedding system, which provides additional clearance for glass-bedding action and the straight section of the barrel. The MPA buttstock comes with an adjustable cheek riser, length of pull adjustment, and monopod.

The 6mmBA and 6.5mmBA also feature a front-mounted bridge with Picatinny rail and a lower mounted Picatinny rail, plus a 20 MOA scope rail. The body has a Cerakote finish of either black or flat dark earth. The MPA 6mmBA and 6.5mmBA are compatible with any AICS or AW compatible magazines.

The Spencer/MPA hand-lapped rifle barrel is produced from 416RQ 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 and hand-lapped to exacting sizes, removing any and all tooling marks. The barrels are tested and verified using a Sheffield Air Gage Inspection System to .0001 inch size variance with additional inspection on a video borescope.

The Stillers Precision TAC Series premium actions, produced for MPA, have recoil lugs ground to .0001 inch flatness and parallelism. 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 Stillers Precision TAC Series bolt, also produced 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 black nitride finish.

Additionally, the MPA 6mmBA and 6.5mmBA Bolt Action Rifles come with an MPA muzzle brake (tactical or bench rest type) and Timney 510 trigger. The MPA 6mmBA and 6.5mmBA each retails for an MSRP of $3,250 and includes the tactical chassis, a 10-round AICS type magazine and a Plano AW Rifle Case.

The 6mm Rifles are available in various 6mm chamberings, including 6mm Lapua, 6mmXC, 6mm Creedmore, 243 Winchester and others. The 6.5mm Rifles are available in 6.5mm x 47 Lapua, 6.5mm x 284 Lapua, 6.5mm Creedmore, 260 Remington and others.

MasterPiece Arms main offices are located in Carrollton, Georgia and its manufacturing facility is in Comer, Georgia.
