LMT Defense 12.5″ Barrel, Mid Length Gas System, 5.56 NATO

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

This barrel was specifically designed to compliment the L7Z1A “Spec War” upper receiver. The short dwell time of the gas system creates an optimal recoil impulse and gas pressure for both suppressed and non-suppressed shooting while maintaining expected reliability.

Designed for the LMT monolithic receiver, this barrel utilizes a low profile gas block, mid length straight gas tube, and A2 birdcage for reduced flash. The barrel is coated and cryogenically treated for long term durability.
