I bought «KOBRA» collimator sight EKP-8-21 in may 2009 for my semiautomatic Bekas-Auto 12/76 with standard dovetail mount. The sight is coming with protective case, screwdriver and lens cloth. The mounting base is included, so you don’t have to buy it. Later I’ll share the information about the sight and test results. From now I can say that after 100 shots (20 of which was 357 Magnum) the sight is just fine, mounting seat is intact, the sight didn’t slide back and aiming speed and convenience proved to be much better so as the twilight firing.
