JG Airsoft R36 Plastic Hop-Up Chamber Unit w/ Bucking for R36/G36 AEGs

Your hop-up is the single most important accuracy component on an AEG, and the factory unit on a budget rifle is often the first thing to go. The JG R36 replacement chamber gives you a fresh start with a properly sealing hop-up assembly designed specifically for the G36 platform.

What you're replacing. Factory hop-up chambers on entry-level rifles often suffer from inconsistent pressure, poor air seal, or buckings that shift after a few hundred rounds. This unit replaces the entire assembly—the chamber body, bucking, and nub—so you're not trying to salvage worn parts. It's built from shatter-resistant ABS polymer, which is the standard material for hop-up bodies and matches what came from the factory on your JG R36.

What's in the box. You get a complete assembly: the hop-up chamber, a bucking pre-installed, a hop-up nub, and the bucking lock clip. That last piece is easy to overlook but essential—it keeps the bucking from rotating under nozzle pressure, which is what causes shot-to-shot inconsistency. Professional installation is recommended if you're not comfortable splitting your gearbox, as this requires accessing the inner barrel and hop-up assembly.

This is a direct replacement for the stock hop-up on JG R36/G36 AEGs. If your current unit is worn, leaking air, or holding adjustment poorly, this is the straightforward fix.
