Picture shows what appeared when attempting to reconfigure left to right hand cocking. Following Page 7 of Owner's Manual (pictured), quickly realized Parts # 60 (Pinching Screw) and #107 (Axis) were missing, having been replaced by a steel pin. Correspondence, and pictures, to AGT, revealed an un-approved design, origin unknown, suggested contact with Krales. Krales, following correspondence and pictures, said return, via non-reimbursable shipping costs, regardless of findings, for inspection. Declined this offer. Oleg, from AGT, after discussion with colleagues, kindly agreed to provide missing parts, at no charge, if I paid postage ($10). Offer accepted. Gun functioned normally, accurate and holding air, would not have realized any problem if not switching cocking lever. Unknown long-term durability of steel pin configuration, suggest U2 owners, not switching cocking arm from factory setting, should inspect. WM
