I ordered a ssalt mount about two weeks ago from SWFA to mount a Burris tac30 on my AR. I arrived in due fashion and I began bolting everything together. I put 18 inlbs on the ring tops without a hitch. Since I already had the fat wrench set I tightened the cross bolts to 18 and was then going to tighten the wrench up to 45. The rear cross lug nut stripped at 18 inlbs, obviously it was a defective nut. No worries, I contacted SWFA and spoke with Skylar. Within minutes they had a new mount on the way to me and said sorry for the inconvenience. This is a great company and great people to boot. So again thank you to SWFA.
