    That is a good read and goes to show how a poorly assembled AR can quickly become trouble. You'd expect it from a badly done "homebrew" but BM should know how to stake by now. Now I have a slightly different story, my buddy's BM castle nut and receiver extension were loctited in and we almost never broke it loose to put on a new RE and stock. What a pain that was!

    Yeah it was red loctite and it was a Carbon 15 so we didn't think it was a good idea to apply heat! :D

    I noticed in the above linked thread its OP listed more issues with low end brands. I thought it would be interesting to drop in one quote.

    Wonder who the guy with a pair of 14.5" middies is? :D


    The snapped hammer pin really points out why it's so important to use quality parts. That single part deactivated the whole rifle - a part that probably didn't cost a nickel less than a milspec pin. And that's the whole point many of us make when recommending paying a little more for quality.

    The same goes w/ staking and torquing properly. It's laziness that shouldn't be supported.

    I would be like a bridge builder using the wrong grade concrete when the correct grade costs the same and is as readily available.

    Added: I find it dissapointing that more people haven't read the linked thread. It's the old story of, those who should, don't and those that don't need to, do.

    Indeed an interesting read. But I plan to keep my DPMS regardless.

    Thank you for bringing up the loctite issue. Yes a lot of the major, good quality manufacturers are now using Blue Loctite (Thread Locker) on their Magazine Tubes and Castle Nuts. I have a rule that keeps me out of trouble and hopefully my students. That is if you do not see a Military Stake on the End Plate Adapter by the Castle Nut. Assume that it may have Thread Locker on it. All of the DEA contract rifles and Rock River Arms Rifles do have thread locker and some others. It is not a problem if you practice heating every Castle Nut that does not have a military stake. You must get them fairly hot and then break them loose with a car stock wrench.
    Also never take for granted that a rifle that you think the manufacturer does not use any thread locker, that it does not have thread locker. It very well could have! Because many are now starting to use it and it is possible the stock could have came loose at one time or another and the armorer used some on it. I use a little Butane Torch made by Ronson which can be purchased at Lowes, Walmart, Menards, Home Depot and other places for under $30.00 to heat Castle Nuts. (Lock Rings) They come with several tips and a can of refill fuel.
    Takes a regular Ronson Cigarette Lighter Refill Canister to refill them that you can buy at any store.
    By the way if you do not heat the Castle Nuts to remove them and they have thread locker it will strip the threads off the Extension Tube when the tube turns.

    Thanks for pointing that out Sniper03! After experiencing it with my buddy's AR I sure wouldn't want it on any gun I bought. Really a shame they do it because proper staking wouldn't take more time or cost more money (except the worker may have to be slightly more skilled).
