![]() ![]() Is it cheaper to get the barrel cut/crowned/threaded again, or have the cap or body of your can replaced? Lapping the can to the barrel? Golden rule: Always fix the cheapest part. Even if you get it started smoothly a die has to be held square or it will remove material unevenly. You can screw up the threads and as we all know, a little bit, added to the possibility of stacked tolerances can lead to a LOT of expense and heartache with a baffle strike. Some folks will just run a die down the threads, but I would be VERY careful. You seem to be in the position of neither. You have two choices: Wait until you have your can in hand and get the smith to thread your muzzle for a nice fit, or the smith should thread it to fit most quality devices smoothly. Suppressor makers are often all over the spec on their threads (one 5/8-24 direct thread can from one maker may thread on with no wiggle, the next may wiggle enough to make you nervous). When we cut muzzle threads we have several test devices that we thread on and make sure they all fit. Is it just me or do the thread valleys on the barrel in question seem a bit shallow? They just dont seem very sharp. Also find out if your smith uses a thread gauge that is 5/8 x 24 class 3a, because if he doesn't then he wont be able to help you. I am willing to bet the smith didn't cut the Class 3a threads. Before you start pouring whatever crap on it and man handling the can on it, I would first find out what threads are the can, and what thread class your smith used. Most cans are 5/8 x 24 class 3a(Except Tac Ops Class3b). What we found was that the smith was using 5/8 x 24 Class 1a?!? threads, and was using a thread gauge of the same. That has happened to me and my friend a few times. 625 in diameter (the total diameter of the tops of the threads. I read the company's website info they advise the 5/8 x 24 threads need to be. I did not want to damage the threads on the can so I did not force it. My buddy's can (different brand) did the same thing. The can would thread on about halfway and stop. I took my rifle to the dealer to test fit the can.

Re: 5/8 x 24 thread - muzzle devices - need advice Would running a 5/8 x 24 die on my threads cut the tops down to size? My buddy said I could sand the tops down but that seems risky. What do I do? Any gunsmiths out there please chime in. The Ops inc brake he installed, 5/8 x 24 fits perfectly, but the yankee hill thread protector i bought, also 5/8 x 24 wont even thread on one turn. I certainly dont want to damage the can and or the threads on my rifle. His advice was to use "never seez" and work the muzzle device back and forth until it fit. I talked to the gunsmith who threaded my barrel, he was strongly recommended here on the hide. ![]() Sorry for the long story but.I need some advice, I bought a supressor and I'm waiting on the paperwork, I don't want to start a debate so I won't mention the brand, it is a direct thread. ![]()
