Ill check it out. he will have plugs and muffs on for target but hunting is a whole differant matter and running a break then can cause issues.
1Biggun, if you're putting a muzzle brake on your sons barrel to bring it up to 16", consider making a Levang type comp. They work pretty well to direct the muzzle blast down range on my 223 coyote gun. For a youngster it would be nice not to have all the muzzle blast frpm that short of a barrel which can make some people start flinching. I also don't think a custom levang style brake would be that hard to make either.
