It has a 500 µm range, with 50 increments of 10 µm (while the original wheel has 15 µm increments). When used with the low nub, it can adjust bucking pressure from 0 to 500 µm, and with the high nub, it can adjust bucking pressure from 250 to 750 µm. The laser engraving on the wheel helps you return exactly to the same "click" setting. The reinforced feeder will increase the feeder’s service life (although it may leave some marks on the nozzle without affecting the normal operation of the parts). Compatible with: - “AEG” type hop-up for TAC-41 (SBA-HOP-30) - “GBB” type hop-up for TAC-41 (SBA-HOP-31).
