My gas key came loose and Bushmaster was gracious enough to send me a new gas key (free of charge) along with screws. Bushmaster insisted that staking the key is a simple procedure and thay even I could do it and that I needn't was cash on shipping to the part to them.

I have a table vice and some wood blocks to hold the bolt carrier in place. I also have a mallet. I do not have a chisel, however.

Please direct me as to what type and size of chisel would be most appropriate for the procedure.

Thanks.

okay... when I searched the first time I did not see it.

Alas, it still doesn't really answer my question-- which is, what is the preferred staking tool.

Thanks anyway.

Preferred tool is a dedicated machine, but the field-expedient preference is apparently a center punch.

I just haven't been able to find a center punch that's tapered sharp enough yet.

Use a flathead screwdriver, put it at roughly a 45 degree angle, and strike sharply. You don't need to move much metal. Do it from opposite sides.

A screwdriver will work as well as anything else, and while I have the proper staking tool, you can't tell the difference after both have been used.

It's not a critical operation. Don't over think it.
