Product Information

This DPMS LR-308 Heavy Barrel is fully chambered in 7.62x51mm NATO and ready to install on an upper receiver. The barrel's 20" length is considered by many to be the ideal size for larger 308-based AR-pattern rifles because it's long enough to produce good velocities with most loads, is not overly heavy or burdensome to carry in the field, and also offers reasonable maneuverability in tight or confined spaces. The barrel is threaded 5/8"-24 for the addition of any compatible flash hider, muzzle brake or sound suppressor, and comes equipped with a Forged A2 Front Sight Base with bayonet lug installed at the Rifle Length gas port position. Constructed from 4140 Chrome Moly Steel, the barrel is finished in an attractive Black Teflon coating to protect it from corrosion. Front sight post, detent and spring are NOT included.
