Re: burris extreme 30mm rings????
Just b/c they aren't. $200 doesn't mean they suck. Mounting surface is smooth " no tooling marks". I challenge anyone to snug tight just two opposite screws on each ring and try to twist optic by hand. "Here's a hint......IT WONT HAPPEN"
now tighten all six to spec, your glass ain't goin ANYWERE! I think for $40somthin you would be hard pressed to find anything better. And as far as the not low enough, I put a fixed 10 bushnell mil/mil/ on my barrett 99 and the small front obj. Was so close the cover wouldn't go on the front rail. It was almost perfect,so low infact,that I could not get low enough on cheek weld to get sight picture to clear up. Bottom line ...they work.I think if they will hold concussion/recoil of. 50,you'll be ok.
