  1. Good to have spares
    Haven't actually used them but for the price is good to have a spare set for when you do need them.

Gas Ring (Split Style)

100% of 100
In stock

This trifecta of rings is designed to create some resistance (gas seal) between the bolt and bolt carrier for some reason, likely to impart magical powers to the bolt. That, or to unload pressure on the locking lugs before the bolt is rotated out of the barrel extension. It could be either, we're not sure. You firearm will still work if one or two rings are broken. Hell, even if all of them are broken/worn out it may still function, but it puts unnecessary stress on the back of the locking lugs which may manifest as excessive wear or chipping.

  • Metal construction
  • Ready to drop in and go
  • Mil-spec
  • Made in an ISO 9001:2008 factory
  • Note that 3 rings are required but they are sold individually.
  • Weight: 1 pixie's sneeze

You get:

  1. One gas ring

Compatible with:

  • Mil-spec bolts
  • Mil-spec bolt carriers

Installation Difficulty:

Tools required: Slot screw driver and or dental pick if you are very careful.

Installation notes: There are 3 of these buggers and they all have a split line sooooooo make sure that the 3 split lines do NOT line up, they should be staggered, in order to form a gas seal. If the splits line up, things won't work as well as they should over time and crud will build up. They will rotate over time and the splits will one day line up but I like to start helping the situation as much as possible. 

Use the gas ring test:

  1. Starting with a removed BGC,
  2. Rotate/extend your bolt out of the carrier all the way (as if its locked in the chamber).
  3. Stand the BCG, bolt down, on a flat surface. Let go so the Carrier is pulled down by gravity.
  4. If the bolt collapses into the carrier under the weight then you need new gas rings. If it just sits there at attention, throw her back in the upper and get shooting!


  1. Strip the BCG down to base components.
  2. Stick the bolt into the carrier and turn it so gravity is trying to pull the bolt out.
  3. If the bolt falls out, the rings are pooched. If not, keep cracking!
