MasterPiece Arms (MPA) introduced the short barrel version of their popular MPA570SST rifle. Built for maneuverability in close quarters while providing extreme accuracy, the new rifle appeals to both home defense individuals and law enforcement officers.
Based on the standard MAC design, the MPA570SST-SBR semi-auto rifle with side cocker is chambered in 5.7x28mm. The 8-inch threaded barrel has a thread size of ½ x 28 and works seamlessly with the MasterPiece series of suppressors (not included).
A Picatinny rail on the receiver top and scope mount allows for placement of any sight or laser system and the MPA short aluminum quadrail provides more area for additional accessories. The MPA570SST-SBR is furnished with an MPA low profile buttstock and side folding attachment and a Strike Industries foregrip. Additional features include an adjustable front sight and one 20-round polymer magazine. Fully American made, the MPA570SST-SBR, ships in a hard shell gun case and offers a lifetime guarantee.
As with any SBR rifle, all NFA regulations apply. See your Class III dealer for more information.
