Modify Accurate Hopup Chamber for M4/M16 Series Airsoft AEGs
by mike w. Date Added: December 31, 2012
This hop up has very good wheel adjustment and gears that make it easy to adjust in very small encrements. The draw back to this unit is it dose not fit in g&p guns with out modification. Good hopup but could be better if the little wings on the sides were thinner it would fit w/o mod.
