I hae a set of like new low Warne Maxima 30mm rings that I would sell. I used them very little and almost exclusively shooting on a bench and they are in perfect conditon. I used them with a Ken Farrell 20 MOA base on a Model 700 Sendero chambered in 300 RUM with a Leupold VX-3 8.5 - 25 x 50 and they performed flawlessly. I now have a 10 - 50 x 60 Sightron III on the gun and do not need the rings. If interested let me know and I'll quote you a very reasonable price.
I have a set of Mark 4 Steel Rings in 30mm, I would need to recheck the height on them. They are unlapped and I can't recall using them on anything. PM or post if interested.
I've got a 1pc. Nightforce 20MOA Rem. 700 long action rail and some 1in. tall, or medium as some like to call them, Nightforce Ultralite rings for sale. Both are LNIB.
