I have one set of brand new in package Talley Lightweight 30MM (MED) scope mounts. The Mediums are .500 in height I believe and would work with most 50mm abjectives or smaller. I am selling so I can get lows as my scope is 40mm objective and there was lots of room for lower rings (thanks guy behind counter who knows all!) These are one piece design and are made from aluminum. For Rem 700/40X and howa 1500. $40 shipped which I believe is about 10 bucks cheaper than what they cost normally. I take paypal as a gift or money order, Thanks
