This SHS Sector Chip / Delayer pulls the tappet plate back slightly earlier in the firing cycle and holds it back slightly longer than a sector gear alone. If your AEG is not feeding properly because BBs are not getting a chance to be fed into the hopup, this may solve your problem. This occurs most often on guns with high rates of fire. (please note: packaging may be generic or labeled as 'Rocket Airsoft', but is made by SHS OEM). Color of the chip may vary (blue, red, etc).
