SilverBack Airsoft MDR 7.62 prototype AEG & R7S on show at IWA.... now.
MDR 7.62 prototype is a "new" very special gearbox design....
and the R7S , has a tactical chassis for VSR-10 and clones , and is a early stage prototype.
Also a rumor of something else ...in a 50. size for the future.... that's possibly another evolution in system
After the surprisingly simple design of the Silver Back SRS... SB has proven to be that little company that could... and will be one innovative company I will watching closely in future.
