Ok, So the BOBRO is really one sweet mount. It mounts solid with 0 movement and hols zero from Lonewolf's sweet review, but since I got mine used could anyone give me a tip on mounting a scope in it? The bolts are crazy on this mount. You actually thread a bolt head on to upside down threaded studs so it is completely backwards from traditional mounts. Once I got my scope lined up perfect in the rings and leveled, It was a huge pain in the ass to try and tighten the rings and keep the scope level since the locking mechanism interferes with the allen wrench. The only way I could get the scope in was to remove the locking mechanism and tighten the scope into the rings, then place this back on the locking part of the mount and hope it was level, if not I had to take it back off and readjust. I wish they had just left the bolts on top.
