I’m looking for a shorter barrel for an old Browning BPS 20ga. My son is 13 and I’ve been taking him to shoot clays. He’s really enjoying skeet, 5 stand, and sporting clays (when we get to use a cart). Previously, we just used rentals from the range to see what he liked. I started looking for a good youth model auto, but had trouble finding anything because of the market conditions. My wife’s dad gave him a Browning 20ga pump. It’s older, but probably doesn’t have more than a box of shells through it. The problem is that it’s full size. I cut down the stock and added a recoil pad to fit his LOP but I need a shorter barrel. It has a 28” fixed choke. All I have seen are 28”, 26”, or 22”. I’d like to find a 24” vent rib with screw in chokes. Anybody got a good source?
