Airsoft Masterpiece Hop-Up Block for Hi-Capa

BRASS HOP-UP AIRSOFT MASTERPIECE FOR HI-CAPA

This hop-up block is made of brass which gives it greater resistance than the majority of hop-up blocks on the market. It is perfectly compatible with external barrels from Airsoft Masterpiece, Gunsmith Bros, 5KU or even Marui of course. Its serrated adjustment wheel allows very fine adjustment of the hop up. I recommend replacing the support bracket with a Marui in order to have a wheel that is even more sensitive to adjustments. For me the best hop up block on the market today.
