Bushmaster Rifle Barrels for Sale

Bushmaster Firearms International, LLC (United States) has a long-standing role in rifle barrels as the factory source for its XM-15/M4-style AR platforms, historically centering on hard chrome-lined 4150-steel barrels (often with 1:9 rifling) and now also offering standalone AR barrels. In rifle barrels, Bushmaster is distinguished by durable, duty-focused AR-15 offerings built for reliable function, including its chrome-lined 4150 service barrels and its big-bore .450 Bushmaster AR barrels with 1:24 twist and 11/16×24 threads for straight-wall hunting, rather than boutique match profiles.
