Turnkey Rimfire PRS Trainer from Masterpiece Arms

MPA BA rifle .22 LR rimfire
Don’t worry — you can get this gun in eight different Cerakote colors: black, bronze, flat dark earth, gunmetal, marine red, NRA blue, green, and tungsten.

To succeed at the PRS game you need position shooting practice — and lots of it. Thankfully you can train affordably using a .22 LR rimfire rig. Decent rimfire ammo can be purchased for 7 to 10 cents per round, an order of magnitude cheaper than centerfire ammo. For the best results, you’ll want your rimfire trainer to sport the same ergonomics and “feel” as your centerfire match rifle. You can get just that Masterpiece Arms 22BA, a “turn-key” PRS rimfire cross-training rig. The MPA 22BA Bolt Action Rifle combines the proven CZ 455 action with a custom Spencer barrel and modern MPA modular chassis. With this chassis you can easily adjust length of pull, butt-pad height/cant, and cheek riser position. Chambered in .22 LR, the MPA 22BA Bolt Action Rifle can change to .22 WMR and 17 HMR through a simple barrel change. So, this gun can do double duty as a .22 LR trainer and a 17 HMR varmint slayer. Basic MSRP is $1599.00.

The MPA 22BA Bolt Action Rifle is available with numerous rugged Cerakote finishes: black, burnt bronze, flat dark earth, gunmetal, marine red, NRA blue, sniper green, and tungsten. Custom Cerakote colors cost $135 extra for the chassis body and/or $65 for the barreled action.

The CNC-machined MPA chassis has some very cool features: enhanced vertical grip, thumb notch, built-in bubble level, MPA trigger shoe, and spigot mount with lower-mounted Picatinny rail. The rig comes with a D.I.P. +25 MOA Picatinny scope base and you can add side Picatinny rails, as well as increase the distance from the spigot-mounted bipod to the rear support. The chassis is also compatible with a barricade stop system, an extra-cost option.

Why rimfire cross-training? Because this stuff is ten cents per round. Premium handloads can run $1.00/round (counting brass depreciation), and the best factory ammo can cost over $2.00/round.

A Rifle is Only As Good As Its Barrel
The key to accuracy for any rimfire rifle is a great barrel. The MPA 22BA Bolt Action Rifle includes a precision drilled, reamed, and honed Spencer / MPA rifle barrel made from 416RQ stainless steel. The hand-lapped barrel is inspected with a video borescope. The chamber is indicated within 0.0001” or less to the bore of the rifle.
