MasterPiece Arms’s new MPAR 556 Sporting Rifle, with an MSRP of $999, is chambered in 5.56×45 (.223 Rem.) and accepts AR-15/M16 magazine. It is differentiated from many other AR-style rifles by its heavy stamped-steel receiver. The Sporting Rifle has a 16-inch barrel with a 1:9 twist and weighs 7.8 pounds unloaded. The MPAR 556 employs a short-stroke piston action enclosed by a lightweight, free-floating, two-piece, hard-anodized aluminum handguard.
A front handguard cap keeps debris out of the gas system while providing strength and stability to the assembly. The operator can select where he wants to place Picatinny rails for accessories.
The American-made MPAR 556 Sporting Rifle also contains a side-folding, 6–position polymer buttstock, locked-bolt action, full-length top rail, angled foregrip, and a non-reciprocating side charging handle with forward-assist.
MasterPiece Arms is located in Carrollton, Georgia with manufacturing based in Comer, Georgia. The company also produces the MAC Defender Series of firearms.
