MasterPiece Arms of Comers, GA has just introduced 6mm and 6.5mm bolt action rifle, the MPA 6mmBA Bolt Action Rifle & the MPA6.5mmBA Bolt Action Rifle. My first encounter with the company’s bolt action rifle was at SHOT SHOW where it was wearing a Magpul PRS stock but it looks like MPA was busy implementing their own vision of a stock for its new rifle and I’ve got to admit that it looks real interesting.
These rifles are built on a MPA tactical aluminum chassis with a Stiller’s Precision TAC Series action and an MPA/Spencer hand-lapped barrel.
The chassis is produced from 6061 aluminum with a v-bedding system. MPA provides additional clearance for glass bedding the action and the straight section of the barrel. That’s a very nice feature to have, but for me it probably falls into the realm of diminishing returns as you almost have to try to create an alignment issue with aluminum v-blocks; however, it’s there if you need it.
The MPA buttstock comes with an adjustable cheek riser, length of pull 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 is finished in cerakote in your choice of 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″ size variance with additional inspection on a video borescope.
The Stiller’s Precision TAC Series premium actions, produced for MPA, have recoil lugs ground to .0001″ 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 Stiller’s 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 $3,250.00 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. Check with MPA for your chambering of choice.
