The Lewis Machine and Tool Gas Ring for 5.56 Bolt carrier groups is a replacement part to keep your BCG functioning reliably. This AR-15 gas ring replacement is made from steel for a long service life and snaps on to the tail end of the bolt. The purpose of AR-15 gas rings is to prevent gas leakage to ensure that there is enough pressure to correctly cycle the BCG. The LMT gas rings are a great option if you need to replace worn gas rings or setting them aside in case you need to replace them in the future.

  • Made of steel
  • Easy to install, just snaps onto the tail of the bolt
  • Only includes 1

AR-15 bolts utilize a set of three gas rings and it is recommended to change all three at the same because differing amounts of wear on each ring can also cause unreliable function. If you want to check your gas rings to make sure they are functioning properly, there is one test you can try. Remove your bolt carrier group and put your bolt in the unlocked position. Remove the cam pin and stand the entire BCG vertically on its face. If the carrier collapses onto the bolt under its own weight, then it is time to replace your rings.
