Just an added thought, as I've seen a good amount of new Altamont 10/22 stocks in various forms, on GB for sale, as another source if you go down that road. I literally wanted the longer barrel on my DSP, because I wanted to utilize a receiver mounted peep sight with a Lyman "globe style" front sight. I forget the rear sight maker, but it was bolt on to the rear scope mount holes - bought the correct height Lyman sight, but the dovetail width on it, is wider than the barrel base. Awaiting my brother in law, a machinist, to shave the sides of the Lyman front sight, the match the Ruger base, before install. I have others to shoot, but it's taken nearly 5 yrs to get to this point for me, obviously not a high priority! Cheers, Bill
