Brownells AR-15/M16 Bolt Gas Ring

Brownells AR-15/M16 Bolt Gas Ring Features The Brownells AR-15/M16 Bolt Gas Ring is manufactured to precise tolerances matching or exceeding the specifications of original equipment parts. Gas rings sit in grooves around the bolt body and seal expanding propellant gas so the bolt carrier group cycles with consistent pressure. Over time and repeated firing gas rings lose tension and can cause excess gas blowback sluggish cycling or short-stroking. Replacing worn rings with fresh properly toleranced parts like this one restores reliable function to an aging AR-15. This gas ring is sold as a single unit giving owners a way to replace just what is needed during a bolt service without buying a full set they may not require. It is a great addition to a range bag or spare parts kit since a failed gas ring can sideline a rifle mid-session. Builders assembling a parts rifle from individual components will also need gas rings to complete the bolt assembly. Brownells manufactures this part to standards at least equal to OEM ensuring dependable performance in standard AR-15 and M16 platforms.
