Yup I bought 3 Marlin 22lr barrels on eBay. The first one had pitting and I messaged the guy about it. So he sent me another one free... looks new . I couldn't do that to him so I sent him another $20 But I got two barrels for $40. Both the old Marlin 66 longer barrel version. I already rechamered the pitted one to 22WMR and polished out the pits. I figured it couldn't hurt to have the bore a bit bigger for 22WMR. I thought about drilling one out for a 38 S&W and trying my hand at rifling but that's a lot of work. Probably never get around to it. I with they could sell receivers on eBay. That would be fun.
