Hey guys has anyone done this before as today I went to put a bird-cage on my AR and it needed indexing approximately 180 degrees. I initially installed the crush washer the correct way and begun tightening, loosening, tightening, loosening the FH...
An hour in a half later I finally managed to index the middle port on the A2 FH but by crikey I had to torque that thing down, like I was muscling that thing on so hard I thought I was gonna break something... I'm hoping like hell I didn't ruin the barrel lol I must of torqued the FH 90-100ft/lbs...
So:
- Will having the FH on so tight effect accuracy when barrel heats up over prolonged use? No doubt the rifle will probably shoot a bit differently now...
- Does any of this sound right? I wanna stress that I was trying to crush the washer, not stretch the threads on muzzle but no doubt that would of happened. Hence why I thought the tightening & loosening technique would of worked. Just didn't realize how frickin hard it was to do.
- Has someone else done this & did you have a similar experience?
Any help is much appreciated!
