The LMT 10.5” .300 Blackout Chrome-Lined 1:7” RH Twist Barrel is a caliber-converting, quick-change barrel for their MRP CQB receivers. This MRP caliber conversion system allows for quick caliber changing between 5.56x45, .300blk, and .224 Valkyrie. The installation process is as easy as turning a couple retaining bolts with the LMT torque wrench.

  • 10.5” .300blk Barrel for LMT MRP CQB
  • 1:7” RH Twist Rate
  • Chrome-Lined
  • Cryogenically Treated
  • A2 Flash Hider Included

LMT’s barrels are incredibly well-designed, made from the highest quality materials for incredible accuracy. The low-profile gas block is firmly attached to prevent leakage or slipping, and the straight gas tube interfaces perfectly with the MRP CQB receivers. The barrel is chrome-lined and cryogenically treated for an extended service life. This barrel comes with an A2 flash hider already installed, so it’s ready to rock at the range.

.300 blackout (blk) is a great cartridge for close- to mid-range performance, especially when combined with a suppressor. Ballistically, .300blk is similar in effect to the proven 7.62x39, commonly associated with the AKM. .300blk is a very flexible cartridge, with load weights for both super and sub sonic velocities.

Note: this barrel will not fit a full-size MRP receiver. This barrel is designed for MRP CQB receivers only.
