Product Description
This piece is designed to fit over the inner barrel and be used when using o-rings to push your hop up up against the gearbox. Sometimes, with different outer barrel setups, you may need tons of o-rings to get it to sit snugly against the gearbox. For example, when I changed my outer barrel it went from 4 o-rings to probably 20. Therefore, I created this plastic spacer and I was able to take out the squishyness of the o-rings and reduce it to 1 o-ring.

The inner diameter is 9mm. This fits fine for my barrel that measured 8.5mm. Please make sure your barrel is smaller than 9mm before buying.

If you need a custom size, please message me and I can create it.
