so i am real close to adding more holes, but i am still confused how much the puck is supposed to acct for manufacturing variances. at least im assuming thats what it partially does. i reused the gas tube after removing the "crimp" in it. attached tonys shorty piston, turned barrel down, and ready to start fitting parts. how do i know if my gas tube is too long, not letting piston go far enought into gas block, and getting stuff outta wack? i assume that out-of-wackness contributes to some shotguns differing recoil impulse? sbs/perm/shortened gas build thanks!!!
