For the time being I'm installing a new NIKON Prostaff with BDC reticle I have laying in the safe until funds get a little better after the holidays. My question is has anyone got any experience with using one of these with there SCAR 17S?? I seen somewhere on here where the SCAR 17 can wreck optics from the inertia of the bolt slamming , Is there any truth to that also . Of coarse my dream optic is the Mark 6 but wife would use the SCAR on me if I bought one of those any time soon. Any help would be great .......Happy Holidays !!!!
