Hey all...

I was cleaning my rifle the other day and noticed the gas key was a little loose on the bolt. I tightened it up with an Allen wrench, and it seems to shoot fine.

Is there anything else I need to do? Should I put some thread locker on the screws or something? I just want to be safe.

Thanks!

You need to stake it or it will work its way loose pretty quickly

It this a Bushmaster, by chance?

Indeed it is! A known problem, I take it?

By "stake" what do you mean exactly?

You need to deform a tiny portion of the cap screw and the bolt carrier to that the scew won't work itself loose. If you can find a M16 manual, it will show you how to stake your gas key into the bolt carrier.

Staking is pushing some of the surrounding metal against the screw for a tighter fit. Take a look at the key around the edges of the screws and you should see some deformed metal. It can be done with specialized staking tools, done with a center punch, or you can use a flat-head screwdriver. I place a flat-head screw driver against the outside of the carrier key where the metal is thinnest, hold it at about a 45 degree angle and give it a few taps with a hammer so that some metal is bent in against the screw head.
