    Should I reinstall my flash hider?

    I removed my FH and FSB because I was trimming it to be a low pro to put an extended rail on. I finished shaving the FSB and painted it. I then reinstalled it. When it came to putting the FH back on I tried putting a new crush washer on and threading the FH to see where it timed and it timed to 12 oclock hand tight, which means I would have to crank it around another 360 degrees to make it line up. Instead I used my old crush washer because it timed at 9 oclock by hand. I cleaned the thread so the FH and the muzzle with break cleaner and applied some Lubriplate 130A to the threads. I just used a small amount of Lubriplate 130A. I worked the FH to 12 oclock with the old crush washer and it is snug as can be.

    My questions are:
    -Should I have not reused the same crush washer?
    -Is a small amount of lubriplate 130A ok to put on muzzle threads to prevent galling?
    -Should I take everything off and redo it with the new crush washer and a different lube/grease on the threads?

    Thanks

    I did this once before and just used slip 2000 ewl on the threads with a new washer but the washer timed better by hand than this one.

    1. Is the FH timed correctly and tight? I use just a touch of rem oil on the threads and tighten/time it. I would leave it be if it's tight and timed

    I'd leave it alone, that's how I like to set mine up.

    Yep it is timed correctly. It is tight and I cant even begin to budge by trying to untwist by hand. I just want to make sure I wont have problems.

    So you think that using some breakfree degreaser and then adding a dab of lubriplate 130A is ok?

    The lubriplate is fine. I use aeroshell 33MS. Due to the heat and fouling the muzzle device and threads are exposed to at the muzzle, a high temp threadlocker like rocksett, resbond ts blue, or a high temp grease is preferred if you ever want to get it back off in the future.

    ok. is it cool that I just used a little or should I have gooped it up? I literally just dabbed some on my finger and smeared around the threads. Sorry, I just want to be clear so I do not have a hard time getting the FH off in the future. Thanks

    Should be fine if you're running unsuppressed.

    It's not ideal to re-use a crush washer. It can over expand and get stuck on the muzzle threads, making it difficult to remove in the future. Using the new crush washer would have been better even though it needed a full turn. Better still would be to use shims.

    At the moment, there's no reason to re-do the muzzle device

    Well I ended up taking off the FH again and putting a new crush washer on. I really had to clamp down on the barrel to get it to go around. I do not have a barrel vice which would have been extremely nice. Instead I rapped it in leather around the front of the barrel and clamped it down in the vice. I would tighten the new washer a bit and release some pressure and tighten it up again until it timed right. I really had to snug the barrel down. It kept wanting to rotate. Just proves that the proper tools help for the job. I thoIght I was going to break my vice or the damn barrel with the amount of pressure I had to clamp down with. I literally had to tighten the vice with my body weight. It eventually snugged up enough. Lesson learned.....I ordered a good barrel vice.
