AR-15/M16 Bolt Gas Rings

AR-15/M16 Bolt Gas Rings

Make: AR-15
Make/Model: AR-15


Manufacturer: Brownells
Model: Function: The gas rings create a gas seal within the bolt, ensuring that the expanding gases produced during the firing process are directed to the gas tube. This gas pressure then cycles the action, ejecting the spent cartridge and chambering a new round.

Number of Rings: There are typically three gas rings on the AR-15/M16 bolt assembly. This configuration provides an effective gas seal for proper cycling.

Material: Gas rings are commonly made of durable materials, often steel or similar alloys, to withstand the high-pressure conditions generated during firing.

Wear and Maintenance: Over time, gas rings can wear out due to the cycling of the bolt. Regular inspection and maintenance are essential to ensure that the gas rings are in good condition. If the rings are damaged or worn, they should be replaced to maintain the rifle's reliability.

Installation: Proper installation of the gas rings is crucial. They need to be correctly aligned on the bolt to create an effective gas seal. The rings should be evenly spaced, and the gaps between them should not align.

Compatibility: Gas rings for the AR-15 are generally interchangeable with those for the M16, as both rifles share similar designs.
