MasterPiece Arms MPAR 556 Sporting Rifle is now shipping, featuring some serious upgrades—including a short stroke piston design and a lightweight, free floating, two piece hard-anodized aluminum handguard with user located picatinny rails.

The MPAR 556 Sporting Rifle has 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. Disassembly is very user friendly, both for access to the internals of the weapon, as well as the piston assembly housed in the front handguard.
