Looking for some pointers. I have a midlength upper I bought last spring that I want to put a flash hider on. It was built with a contoured, threaded and chrome lined barrel. Because of the ban I had it shipped with a thread protector pinned on. I am going to try to grind around this pin and try to get it out. The builder told me there is probably some loctite in there as well. The pin is clearly visible in the 6 O'clock position. My plan is to take out material around the pin and leave as much of the pin in the middle as I can. Then grab the pin with some channel locks and beat that thread protector with a hammer until I can get the pin out. If you know a better way I would live to hear about it? Is there any thing I can do to soften up any loctite that may be on the threads ( I do not know what color it is yet)? Any advice is appreciated. JR |

Change of plans. Grinding around the pin was not possible so I just tried to work it and the surrounging material down until I could get the nub out. I could see the outline of the pin all that way down. Never did get a nub. I stopped when a little hole with a line running across it started to appear. That would be a thread. I am down to depth. Not knowing what type of loctite is in there. I have applied quite a bit of torque the the muzzle cap. no budge. What can I try next? JR |
Smack the pin side of the muzzle hard against a block of wood. The pin stub may fly out. This is how I removed a blind pinned and welded nuzzle brake.  The pin stub is lying between the muzzle and the remnant of the brake. |
how's your zero now HM?
It changed a couple of clicks after I put the A2 FH on it. The muzzle of the rifle is fine, the only sign of trauma is the hole for the blind pin which had no effect on the atachment of the flash hider. The muzzle brake is now a fishing sinker. |
You might also drip a couple of drops of acetone on it after you warm it up, this should let it penetrate. Just don't put acetone on it if it is red hot as acetone has a low flash point. |
P.S. Worry more about getting the acetone around the pin stub. Thats gotta go first. If you get it gone, the rest will come. I would stick the muzzle in boiling water and then submerge it in acetone. |

HM Soaking upside down in Acetone was the key. After 20 min of that it was good and cold from the acetone. I dried it off and feathered the torch into the muzzle for about 20 seconds. It must have shrunk the barrel inside the cap just enough because it came right off. Thanks for the help. Hello No-ban JR |
