Hopefully he didnt torque it down over 30ftlbs. Once you go over that mark it constricts the muzzle and your accuracy goes to hell.

Typically i set my wrench for 30lbs and torque until its lined up or hits 30ftlbs. Since thats a non directional brake, meaning it doesnt compensate for bullet torque it should be lined up.

Kinda why i prefer to diy one simple jobs like this.

Judging by the fact I can't get it off, I'd say he went over the 30ft lbs mark.

Took it the original place that installed the Dynacomp and showed a guy. He said it won't cause any problems. I told him it should be aligned. He told me they can do it but it would take a few days. I decided to take it to another gun store that has an armorer. Everyone employee took one look at it and said it wasn't right. I left it with them and the armorer will call me and let me know what's up. I'm thinking of having the barrel chopped and the muzzle brake pinned. Anyone have any experience with that?

Are you in a ban state? If not I'd leave the barrel 16" and not pin the muzzle device. Why go to all that trouble for 1.5", index it and torque it properly.

I can't get it off. No I am not in a ban state. I'll just have the armorer fix it. This is my first build. I don't wanna break anything.

I'm not going to. I'm just gonna have the armorer index the Dynacomp properly.

I wrote a bit on aligning muzzle devices a bit ago ... It's pretty easy. I'll post it here when I find it.

A threaded barrel with a thread pitch of 5/8 - 24 has a 5/8" inch threaded diameter and 24 threads per inch of threaded barrel.

Every 360 degree turn of a device advances the device 1/24th of an inch.

1/24 = 0.04166666666 inch

0.04166666666/ 360 = 0.00011574074

Every degree turned advances the device 0.00011574074 inch

So if my device, torqued down to spec is advanced 45 degrees ahead of being timed, I would have to create a shim that is 0.00520833333 inch.
