I like the HK claw mounts as well. and that HK 30mm mount that Biggerhammer has for sale is at a great price, those typically go for $250-350. can also get 1" inserts for the 30mm rings.
HK91 with HK 30mm claw mount, SS10x scope, this scope might be too big for the HK 30mm mount, might change it to a HK Arms mount and 30mm rings to get it up higher, will find out today at the range, its just a damn big scope, had no idea untill it showed up yesterday how big it really was ;)
HK93 with HK claw mount, Hensoldt 4x28. I swaped this from my 91 to 93 it was still zero'd horizontaly, just needed a little change in the elevation, pretty cool if ya ask me
I have the BT low mount on my HK94 with EoTech and like it alot for that. Heard the Leepers are actaully a very nice copy
