I have a pair of very lightly-used 1" PRW rings that I'd sell to you. They are either Med or High I believe (pretty sure they're MED). I used them on top of an ARMS #19 base (which I am also selling) for one of my ARs. When I get home tonight, I'll measure the amount of "rise" between what would be the top of the base and the bottom of the ring opening so we can determine if they are MED or High rings and if you want them. I'd send them to you for $25 shipped and I could work a package deal for them if you want the ARMS #19 too. I would also consider trading my #19 for your #38... Just let me know. Thanks.
