MasterPiece Arms Introduces the Multi-Barrel, Multi-Caliber Capable MPA 65BA-SL Bolt Action Rifle

The rifle incorporates the West Texas Ordnance Switch Lug System, which allows the shooter to change the barrel in five minutes, without affecting the accuracy.

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 65BA-SL Bolt Action Rifle. The rifle incorporates the West Texas Ordnance Switch Lug System, which allows the shooter to change the barrel in five minutes, without affecting the accuracy. The Switch Lug System gives the rifle the capability of using multiple calibers. The rifle comes chambered in 6.5 Creedmoor with a hand lapped Spencer barrel. The action is the new Curtis Custom Axiom and the shooter can choose either the MPA Chassis System or Competition Chassis. The rifle has been built for extreme accuracy and is guaranteed to shoot at least a 3/8″ MOA.

“We always have our finger on the pulse of the precision rifle community. We noticed that many PRS shooters have need for a secondary caliber or potentially a trainer rifle usually chambered in a less expensive or easier to get caliber. With the incorporation of the Switch Lug System there’s no need for a second rifle. Simply get a second barrel in your preferred caliber, and possibly a spare bolt and magazine and now your match gun can also be your training gun. In addition, the Switch Lug System also makes barrel replacement a very simple task, all you need is a Torx wrench to make the switch.” said Phil Cashin, president of MasterPiece Arms.
