Check w/ Parsons Optical. Gil Parsons is licensed by Lyman to build, repair, etc, the Lyman Targetspot scopes. A few yrs ago, he also made a Lyman-clone BPCR scope. Very impressive scope.

I have 2 Parsons scopes & Can vouch for his quality of work. Those scopes w/the newer Malcolm mounts along w/ the newer MVA scopes & improved Malcolm mounts are NRA approved by silhouette.
Or you could get a scope from
RHO Instruments
http://www.lautard.com/RHO/@ time, I had an RHO, but sold it as it was a PITA to adjust for the wind. I dont know how his improved mounts works as I have seen one.
