Brownells 75th Anniversary - A Shooting Heritage
Menu

Criterion stainless steel match grade button rifled barrels feature a 223 Wylde chamber and 1-8" twist for enhanced accuracy potential with both .223 and 5.56 NATO ammunition. Each Criterion barrel is individually hand-lapped to ensure smooth, consistent lands and grooves. Gas ports are optimized for barrel length and chambering to help ensure reliable cycling. Bull contoured stainless steel barrels incorporate an 11° target crown and barrel extensions featuring M4 feed ramps to aid in smooth, reliable feeding. Barrels now feature a dimple opposite the gas port, so screw-on gas blocks do not shift during firing.
