I bought it lightly used late last year, and used it to check the accuracy of a specific rifle. I am done with that project, and it has sat on the bench. It had one of the C-clips from the forward tensioner fly away during the install, but it did not effect the function of the mount. (You just have to be careful when putting it together. So, I have all of the parts, minus one c-clip. Retails at Brownells for $184.00. $110 plus actual shipping. E-mail works best: billofoz AT gmail DOT com
