I hate to be the one to break this but it's not an original concept. While the work performed is stellar, Docter optics have been mating to pistols' rear sight dovetails for some time.
Needless to say a Docter red dot is sufficiently strong enough to withstand the recoil forces generated by a real gun, which likely explains why you pay $500+ for one. That Firepoint appears to be a copy of the Docter, and hopefully is cheaper because I would be none too happy about a BB shattering the lens of a $500 red dot.
Do you plan to offer this as a service? I can see people wanting this done professionally and who better to perform the work?
