i went to walmart to grab ammo today...they actually didnt have any 22-250 ammo but had weaver quad lock mounts and bases. looked like good quality...they were medium. put them on(was cussing about being quad lock at that time. they pretty much have 4 rings (8 allen screws) instead of the typical rings. but i like them. seem nice and sturdy. the mediums are probably a shade high..could most likely get away with low, but the scope is close to sitting on the barrel..so lows may been too low

thanx for all the replies.
