Thanks a lot for the responses guys! I figured it was an aftermarket, I was just curious where I might possibly find a sleeve for it. It's nice at the range, but not what I'm looking for for hunting. I may cut and re-crown, but for now I may just try and get a sleeve in case I decide to sell/trade the gun down the road. Some guys may find it a plus that it has the brake.
Anyone know where I can get a sleeve for it?....thanks for the b-day wishes by the way!
