I have a Ruger American rifle, I like it a lot, but it's a hair too long (length of pull). I removed the recoil pad which shortened it by about an inch, the length fits me pretty good but now I need a butt plate. I was thinking of a piece of .062" aluminum but it would be pretty slippery on my shoulder. This is a .223 Remington so I'm not concerned about recoil but want something that won't slip off my shoulder. Does anyone have a recommendation?
