Element H&K USP .45 Pistol Under Rail Mount Black
Fits my KSC USP Tactical (full-size frame) and M6 light. The tab is a 3-4 mm shorter than the pistol rail, so it may slide back and forth. Only the large screw may be installed, as the smaller nut is not recessed and interferes with rail accessories. The "trademarks" read "full-size flame", instead of fRame.
