MPAR 456

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.

    I sent them an email asking about the possibility of a folding charging handle and if the gas block was adjustable(e.g. FAL) and here was their response:

    "Thank you for contacting us. At this time the side charging handle is fixed as it features a forward assist.

    Our gas block is also fixed but valved to be self-regulating to ensure performance with a wide variety of ammunition."

    Have one these MPAR's for several weeks now. Nice weapon. Ran 200 rounds through with no failures. Overall, I really like the rifle. I was looking for a piston AR, but could not find one under $1300. Paid about $800 for the MPAR, which has a short stroke piston system. The side charger is really a great feature. I never really liked the charging handle on an AR, but this MPAR allows you to charge the system while keeping it shouldered. Its just a neat desgin. Handguard is big, but it definitely gives the rifle a unique appearance. The bolt carrier group and recoil rod assembly is a complete unit. Just slides right out of the upper. The overall finish is good. The side folder is also a unique feature. Fires just fine with the stock folded. I like it!
