Other than the muzzle loader forearm, I use only one for all my Encore barrels. I use a 12ga Flextech forend and apply spacers(those magic pieces of shotshells) as I switch from 12ga.... down to Katadin...on down to standard contour. Actually, I have two pieces of leather belt cut for the thickest application, but they work fine for me. Yes, if you look close, there is a little gap, but I know my barrel is free-floated, it doesn't bother me in the least and you can't even see it from your house
