am sure this has been asked elsewhere but, here goes. want to install a side baffle,ports on top,blank on bottom brake on a rem sendero 338 rum with factory ss bbl .830'sh @ muzzle. one company in the n.w. kinda gave me the finger and one in a central state won't blend the rear of the brake to match muzzle dia. where and who do i look for to preform this small task? i see alot of sticks w/ brakes that have no shoulder where brake meets barrel. any refferals? thanks in advance, laura
