Nothing to it. I am retired and have more time than money, I just kept thinking until I got the idea. By the way, that early Contender was a pawn shop deal that had a stainless 10 inch .22 LR barrel and a two screw forearm even though the barrel had only one lug. Since I got the whole rig for $300 out the door, I had some room to tinker. I ordered a single screw forearm from Midway and then found a .221 Fireball barrel for $70 plus tax, so I had to figure if a round barrel forearm would work on an octagon barrel. It looks a little different, but everything works well.
