crazyNCman got the A Plus Devil Hop-Up Bucking to install for an AEG test after doing an airsoft retailer review. He looked into its claims of increase in range and accuracy but it seems that he wasn't really impressed with it. He'd rather stick with the R-Hop which are made for AEGs and also recommends that you do likewise. No actual test footage shown, so you might have to do your own to confirm his findings.
