I was plinking with one of my ARs this weekend. It started short stroking, then wouldn't eject at all. I disassembled and found that my Gas key was loose on the bolt carrier. It was also damged because it hit the gas tube at a bad angle and mangled the opening of the key.

I have a new key and screws on order.

Question 1: This particular key did not have its screws "staked" like my bushy bolt carrier. I am assuming this led to the loosening. Does it need to be staked, and if so how is this done?

Question 2: Can I just use loctite on the screws instead of staking them? What color loctite should I use.

Thanks.

Staking. The military manual on M16s, also recommend staking.

I would think that locktite can hold up to any heat from a rifle as its used on cars. Engines run pretty hot as well.

Thanks for the responses. I fell kinda stupid for letting the thing work loose witout checking it.

It looks like staking should be easy, so I will go that route.

After further inspection, it appears as though there was an attempted staking but it only marked the key and did not deform the screws at all.
