Based on the standard MAC design, the MasterPiece Arms 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). Built for maneuverability and accuracy in CBQ scenarios, the new rifle serves well in home defense or law enforcement capacity.

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 MasterPiece Arms 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.
