MasterPiece Arms Introduces the MPA 22BA Bolt Action Rifle


Comer, Ga. – (July 2017) – MasterPiece Arms (MPA), manufacturers of the MPA BA Rifles, Chassis Systems, Defender Pistols and Carbines, Suppressors and MPAR Rifles, is pleased to introduce the MPA 22BA Bolt Action Rifle. Built upon the MPA CZ455 BA Chassis, the MPA 22BA Bolt Action Rifle will provide the shooter with the ability to adjust the length of pull, cheek riser position, add side Picatinny rails or a night vision bridge, as well as increase the distance from the spigot mounted bipod to the rear support. Chambered in 22LR, the MPA 22BA Bolt Action Rifle can change to 22WMR and 17HMR through a barrel change. The rifle also includes an MPA Trigger Shoe and DIP25MOA Picatinny scope base.

The chassis is machined on MPA’s CNC Horizontal Machining Centers to exacting tolerances from 6061 aluminum. MPA’s unique pocketing system reduces weight and increases the structural integrity of the chassis. The chassis also includes a built-in bubble level, thumb notch and spigot mount with lower mounted Picatinny rail. The new MPA Enhanced Vertical Grip is also included. It is also compatible with a user locatable barricade stop system, which requires the purchase of a rotating barricade stop.

The MPA 22BA 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 MPA produced buttstock features an adjustable length of pull, recoil pad with height and cant adjustment, adjustable cheek riser and an adjustable 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 very strong lockup of the cheek riser plate and recoil plate assembly.
