I have a set of used like new 30mm Badger Ord steel standard height rings and a set of used like new 34mm steel M40A3 height Badger rings used by the USMC on the M40A3 with the S&B PMII. The 34mm has the thicker six screw ring up front.
These both came with optics I purchased in the past and then decided to use LaRue QD mounts as I was not mounting to bolt guns.
30mm rings are $110 plus shipping.
34mm rings are $140 plus shipping.
Please email me at joshuasurowitz [at] gmail [dot] com if you are interested.
