The Masterpiece Arms MPAR 556 is now shipping and can be purchased from your local dealer. For those not familiar with the rifle, it is a piston-driven rifle that looks similar to the AR-15. Some parts are interchangeable with AR-15 rifles, such as the magazines, but running the gun is different.
The MPAR 556 has a non-reciprocating charging handle on the left side of the gun that incorporates a forward assist. A folding stock is standard on the MPAR 556, and the gun will fire normally from the folded position.
The gun is chambered in 5.56 NATO, and has a 16″ barrel with a 1:9 twist. The handguard is aluminum and allows the shooter to locate various length Picatinny rails at various points. The gun comes with an angled foregrip.
MSRP is $999, which may make it very attractive to someone looking for a piston driven alternative to the standard AR-15 rifle.
