AR bolt carrier gas key

[50 shooter]

So I'm having problems with my AR at the range today, short story, I find that the gas key bolts are loose and the bolts weren't staked properly.

Is there a special tool or can I take a punch and stake them between the bolts and the key side or do they need to be staked from the sides of the key body towards the bolts?

Just want it to be correct as I'm really not happy about the whole issue, some lazy ass couldn't take the time to do his job correctly.

There are special AR staking tools ( http://www.brownells.com/gunsmith-t...5-m16-carrier-key-staking-tool-prod29337.aspx ), but you can use a regular punch and stake them yourself.

Before doing this, you should completely remove the key and thoroughly clean the mating surfaces of BC and key. Otherwise, there is a higher potential for the key to come loose again or gas to leak out between the parts.

Thanks for the help, I'll be ordering the tool.
