Rock solid hop, every shot
The Rocket ProWin style hop up chamber, made by SHS, is a one piece CNC aluminium upgrade for M4 and M16 airsoft AEGs. Where a stock plastic chamber can flex and let the hop setting drift, this rigid alloy unit stays put, giving you a stable, repeatable hop for tighter, more predictable shots.
Precise rotary adjustment
A rotary wheel adjuster replaces the fiddly stock lever, letting you dial in the hop with fine, controlled increments. Once set it stays set, so the hop will not wander mid game and leave your BBs flying high or dropping short.
Better seal, better range
The precision machined body improves the air seal between the nozzle, bucking and barrel, so more of your gas or spring energy goes into the BB. The result is better range and consistency across a wider spread of BB weights.
A worthwhile workshop job
This chamber fits M4, M16, SR-16, M4-RIS and other compatible Version 2 AEGs. Because fitting means re-seating the barrel and bucking, we recommend it is installed by an experienced technician. Our team can handle it through our airsoft repair and servicing, and you can find more parts in our airsoft accessories.
