Help w/ Bolt gas rings

Post by DaveM » Sun Jan 22, 2017 2:30 pm

One of the bolt gas rings broke and bent. I've ordered a pack of 3 new ones.

1. What's the easiest way to replace them?

2. Do I simply replace the broken one or do I replace all 3 at the same time?

Thanks, Dave

Why not replace 'em while you're in there?

I switched to JP Enterprises Enhanced (one piece) gas ring and it works fine - No worry about "lining up" the conventional style gas rings and they are suppose to last a lot longer

I'm still in the "learning stage" on the AR platform. I only have 4 of them. [smilie=033.gif]

There is a particular way to install which wasn't mentioned in the video. "Gas rings are produced via stamp cutting. This means that the top side edges will be round, while the bottom side edges are sharp instead.

When the gas rings are mounted to the bolt channel via your finger nail, you have to make sure that the stack of rings are all installed with the bottom sharp edges towards the tail of the bolt. This puts smooth edge against sharp edge, with the sharp edge facing the tail of the bolt to give a better seal from the gas being driven against them at unlock.
Note, depending on how sharp/bur'd the rings are brand new, it may not be a bad idea to take a light stone to the burs so they they will not catch on something.

Some times assemblers will get in a rush, and install sharp edge toward sharp edge, and this will cause the rings to bind up against each other to cause the damage you see.

As for gas rings, they are cheap enough, so pick up a few sets to cover you down the road as well. "
