I got my 10mm Mech Tech CCU last week. It seems to be a very sound unit. I took it to the range and it shot great. took about 4 shots to dial in the eotech. It took my 180gr golden saber out of 5.2 barrel from 1250fps to 1420fps out of the 16.25fps. It is a blast to shoot. it even feed my my converted Asian Military 45acp mags with no problems. Now the only problem it the amount of ammo it goes threw. Wanna kill these ads? We can help!
