Here is an add for an MSG 90 clone made by Dan Hoodenpyl with the link below
Hk Msg90a1 (Complete)
Douglas Air Guaged match barrel
70,000 psi yeild reciever rails
Throw lever Msg90 mount
4,000.00 and No wait (Wow)
OK the "No wait" part... I would only believe that if I were standing there... My roomate waited almost 5 months for an MSG 90 scope mount that was supposedly "in stock and ready to ship." I waited 5 months for a part for a Galil I NEVER GOT... If you dealing with this cat (an I am not saying his work is badbecause he takes forever and you NEVER get to see it! ! !) just don't do it unless you are there in person and he has the item in HAND.
Edit I just found this. Hummm maybe not even if you are there in person...
