Got a coyote hunt coming this weekend and I'm using my 223 AR with stainless heavy barrel. Don't really want to paint it but have a few extra feet of burlap from last years Halloween costume. Was thinking about just doing a simple cover of burlap from forearm out to muzzlebrake, and I don't think with the heavy barrel this would affect poi or accuracy, but just wanted to confirm. Any help or info would be appreciated.
