I am a newbie and I wanted to remove the front sight of my LMT 14.5" barrel and replaced it with something better. But in order for me to do that, do I first have to remove the flash hider before I can remove the sights? Would I ruin or destroy the thread of the barrel? How are these flash hiders attached? Welded or using Loctite? How would I remove it? Any suggestion is greatly appreciated. Thanks in advance.

If you have a steady hand and a Dremel, you could cut the FSB real thin around the barrel and break it off.

There are clamp on sight bases such as the Yankee Hill. That's what I'm considering doing to one of mine.

If they're post ban, they either have to be silver soldered on, or blind pinned, correct?

Silver Solder melts at over 1100, iirc, so you need a MAPP gas torch to get there. Maybe not good for the barrel, according to some folks.

Blind pinned, I don't know what you can do for that.

WHat is permed on it, and who did it? Ive removed Hundreds of permed brakes/hiders.(i work for an AR-15 Cutom shop) Every Manufacturer, as well as every smith does it a little different. I would recomoend NOT heating it up and trying to turn it, as this will more than likely rip all the threads off your muzzle, and being a 14.5 BBL, the only way to fix would be go shorter which equals SBR. Most factory perms have one/two hardened pins placed in small divots, in the barrel thread, and are then welded over, blasted, and reparked. Usually you can see the weld spots, they appear darker ( BM welds theirs Top and bottom, ARmalite Welds on a 45 degree angle with a 1/8 pin inside, Most small smiths weld on bottom. Take to a GOOD smith and have him grind / mill the hardened pins that are protruding into the barrel out. THEN unscrew FH then when you done with your new parts installation, have a new muzzle device re permanently attached. I have seen too many times people trying to remove their own FH's and MB's and dremel / drill right into the barrel ruining the end of the barrel, Trust me its much easier to take it to a pro, and have it done rightthe first time, then to attempt it yourself and end up spending more $$$ to get it fixed AFTER you fuck it up.
Anyway thats my $0.02
