The LMT Defense MWS 6.5 Creedmoor 20-inch barrel is a stainless steel, 1:8 twist barrel with 5R cut rifling for LMT’s MWS upper receivers (LMT part no. R-LM650B220S). LMT includes a low profile gas block, a straight gas tube and an A2 flash hider, so the barrel comes ready for a direct-impingement build. The 20-inch length and 6.5 Creedmoor chambering point it at precision and long-range AR-10 pattern rifles, where a heavier, high-ballistic-coefficient bullet needs the faster 1:8 twist. It is a straightforward way to build or re-barrel an LMT MWS rifle for distance work.
