Disassembled my Ultimate BP Xpress, packaged it up and its on its way to AZ to Arrowhead Sporting Goods (ASG) for the new ASG designed breech plug. No more issues with gas cut nipples, no more extensive manual labor and best of all, it'll handle BH209 without issue. No more over priced pellets. I strongly urge anyone with either the Ultimate Firearms Inc rifle, or the Remington Ultimate Muzzleloader, to have this conversion completed. The time and money saved will more than cover the installation down the road.
