The new M4A PRO hop-up block is ideal for upgrading your AEG M4 airsoft replica. It features very good build quality and has a precise hop-up adjustment system. In fact, it is designed with a numbered, notched wheel, allowing you, for example, to adjust your trajectory according to the weight of pellets used once you have found your correct setting.
.
Furthermore, this hop-up block is dust-tight thanks to vinyl side panels blocking access to the machined holes. There's also a wedging system in line with the nozzle and barrel via 3 O-ring seals and 3 springs at the top, bottom and middle of the block for perfect centring.
The M4A PRO MAXX MODEL hop-up block embeds a ball retention rocker system to retain the bbs when the magazine is removed from the replica. This system automatically releases when a new magazine is inserted for optimal operation.
