You can do a cheap staking job with a hammer, punch, and a vise.

Or you can buy a dedicated staking tool (this is the one (http://www.m-guns.com/tool_new.php?product=pmoacks), this will do too (http://www.m-guns.com/tool_new.php?product=moacks)) and do it right.

Or you can go to a gunsmith and pay a little for him to use the right staking tool (if he doesn't pull out a MOACKS, go somewhere else).

Or you can do what several of the manufacturers do, and simply torque it down the proper ammount and use locktite. Or you can not worry about it at all, and simply keep an eye on it as part of your regular maintainence and cleaning routine. Do whichever floats your boat. I have several BCGs that came staked. As well as some that did not. And one M16 bolt that I built myself, and didn't even know what staking was at the time. None of them have shown any signs of coming loose with use yet.

What he said. While it's not a bad idea to properly stake your BCG, I really think a bit too much hoopla is made of the whole thing. We have some shooters thinking that just because there isn't a clear, deep groove through their gas key bolts like they saw on a Colt BCG, their upper is just going to fly apart one day. :eek:

It's one more little detail that the top-tier manufacturers use to justify their prices. You have to decide whether it's worth it or not.

For a range toy or hunting rifle, it's not that big of a deal. Do it if you feel like it. For a duty weapon, it's probably a reasonable precaution to take.

ns209,
If i were you I'd keep in mind the availabilty of S&W Uppers. Some of their upper receivers are pretty hard to find. I spent awhile trying to find the M&P 15T upper to no avail (unless I wanted to pay a hefty premium)

Any 5.56 upper will work fine on any 5.56-compatible lower. There's no reason to get wrapped up in "matching" your lower. M&P uppers are good uppers though if that's the way you want to go. Colt, LMT and BCM are also top of the line.

As reidnez said, gas key staking is way down on the list of things to be worried about unless you're going into combat.

Just stake the dang thing and you will NEVER have to worry about it...
