    Castle nut - buffer tube - C5-A

    Am I good with my desired end plate, buffer tube, castle nut... then a bit of C5-A on threads @35-40 ft-lbs? Then stake end plate properly.

    Yes, no, better way?

    I wouldn't use a copper based compound between 2 pieces of aluminum but what do I know.

    OK, thanks, I found some AeroShell 33MS and I meant 40 in/lbs. I'll go that route. I never have understood the whole situation with the copper content. So I will stick with that on the barrel nut and use AeroShell on the castle nut.

    The copper in Loctite C5-A is not as worrisome as the graphite that it also contains. I would use the AeroShell 33MS instead. Though Iraqgunz uses C5-A and has had no problems with it.

    The 40 +/- 2 in-lbs was a typo, the correct torque spec is 38-42 ft-lbs.

    Why not just use the Aeroshell on both?

    To reiterate;
    Torque is 38-42 FOOT POUNDS for the castle nut.

    I have been using Loctite C5-A for the better part of decade. I use it on my personal guns, and have over occasion pull them apart and swapped stuff around. I have yet to see it cause any issues at all.

    I thought you weren't supposed to use Loctite on any of it.

    Loctite makes more than just thread lockers. C5-A is anti seize.

    At your advice I've also used it on a few occasions now. No problems whatsoever.
