    got in my stag upper a few days ago and got around to pulling it apart today. I know the castle nut on the buffer tube has not been done at all, but how does this look?

    I'd be fine with that staking job.

    I think Stag staking has gotten better recently, but I still like it done a little more than that.

    That is better than nothing though.

    I'll probably get flamed for this but.


    Some of my unit's older Colt's look about like that, maybe just slightly more.

    I wouldn't worry about it in the slightest. I might do a better job of it, if you were going to do the other one. That said, my castle nut isn't staked either, just torqued.

    I'm not sure about now,...but for a while ArmaLite was only using LockTight
    and torquing them. A friend in Georgia has a rifle that is done like that, it has 7k rounds fired without an issue.

    That staking is fine. You can see that the inside of the hole has been deformed to provide friction against the screw, which is the whole point. I like the staking my PMOAKS does better, but yours is fine.

    As far as staking the castle nut, get a spring-loaded center punch from a hardware store. They are usually about $8. Grind the tip down (I used a Dremel) so that it's rounded, and go to town staking the end plate into the castle nut indentations. Slow and steady is the key. With my center punch, I usually need 20-30 impacts to achieve one stake.

    Loctite does nothing because when it heats up it loses it's effect.

    Leave well enough alone, check it when you clean. That should hold up for quite some time. Last thing you want is to deform the rails that run alongside the key...

    Not good enough. I had to stake the bolt carriers on both of my previous Stag builds. the bolt itself should be pushed in a bit from the metal on the carrier.

    That depends on what Loctite we're talking about. Some grades are damn near permanent and made to be heat resistant.

    The tougest I am aware of is Red and it will come loose with heat. A friend of mines Armalite started malfunctioning at match. Checked his rifle out and found the gas key loose. I tightened it down and used red locktight to finish the match. Later I staked it with my MOAKS tool. But Armalite had not staked his carrier key at all.

    Don't they make a sleeve retainer for cylinder sleeves? If it will work in that application, I'd think it would work as a thread locker and wouldn't be affected by heat.

    Might be wrong on that though, as I don't do engine rebuilds.

    I have a compensator screwed onto a 1911 barrel that's held on with nothing but Loctite red, since 1988, through around 20k rounds, and it hasn't budged. It probably isn't subjected to the heat an AR carrier key gets, though.

    The thread locker to use for these sorts of applications is Rocksett. It's a ceramic-based locker that's good to 2000F+. It's what AAC suggests for their flash hiders, comps, and QD mounts. You have to de-grease thoroughly before using it, but it is very good stuff.

    Never heard of it before, but found it here: http://store.flexbar.com/merchant2/...duct_Code=15015&Category_Code=Adhesive-Cement

    Looks like great stuff!
