LMT MRP 14.5″ 5.56 Piston Barrel, Gen 2

This LMT 14.5” Chrome Lined 5.56×45 1:7” RH barrel is designed to match the LMT MRP or MRP CQB quick-change barrel systems.

The piston and gas system has already been installed to match your MRP upper receiver. To install this barrel, use the factory torque wrench to release the retaining bolts at the base of your handguard, swap this barrel in, and tighten the bolts down to LMT’s spec. If you want to change calibers or barrel lengths, we offer several other MRP barrels to match your needs.


  • 14.5” Chrome-lined 1:7” RH Barrel for MRP or MRP CQB Monolithic Upper Receivers
  • 5.56×45 Caliber
  • Cryogenically treated for maximum durability
  • Short-stroke piston
  • A2 Birdcage Pre-Installed

This barrel is made for the LMT CQB/MRP Monolithic receiver. It will not fit MWS receivers.
