A PU scope and a POSP are are completely different.The POSP scopes are based on the original PSO-1 scope which was designed for the Dragunov and usually have either an SVD or AK type integral mount (a SVD version sits lower than the AK version and has they have a different clamping arrangement due to a different side rail optic mount and the difference in eye relief, a SVD scope sits further forward on the rail.).POSP mounts are available for Mosins and there are POSP variants for Weaver type mounts available.Sixshot6 wrote:
How do you tell an original russian PU from the POSP modern variants if I may ask?
PU scope, mount is two piece, scope seperate from mount POSP/PSO-1 type, mount integral with scope body, SVD mount POSP with AK mount, mount still integral with scope body PU scopes have steel bodies and steel mounts and aren't filled with nitrogen (genuine ones anyway) whereas the POSP/PSO-1 scopes have magnesium alloy bodies and are nitrogen purged to prevent fogging.
