LMT Defense MRP 12.0" Chrome Lined 1:7" twist 5.56 Piston Barrel (R-L7MC1B)

12″ Piston Chrome Lined 5.56×45 (.223) 1:7″ RH twist barrel

Designed for the LMT monolithic receiver, this barrel utilizes a piston operating rod and has an A2 birdcage for reduced flash. The barrel is phosphate coated, chrome lined, and cryogenically treated for long term durability.

Due to the use of the proprietary LMT piston system that produces the lightest recoiling piston gun, this barrel needs to go into one of THREE specific LMT MRP uppers: the 11.5" "Shovelnose" variant, and the 9.25" CQB uppers in M-LOK or Quad Picatinny rail.
