LMT® 18″ Stainless Steel Finish 1:8″ RH 5R cut 6.5 Creedmoor barrel for MWS upper receivers. Includes low profile gas block, straight gas tube, A2 flash hider.

These engineering test barrels were produced SOLELY to determine the accuracy difference between a “SS Finish vs Nitride”. LMT determined there is no measurable accuracy difference after test firing each barrel 5-15 times. These 19 test barrels were produced and tested to the same standard as any other LMT barrel.
