Factory-original chamber for reliable cycling

The VFC M4 OEM GBB Hop-Up Chamber is a genuine factory replacement designed to restore proper sealing, feeding, and cycling reliability in VFC and Cybergun M4 series gas blowback rifles. Manufactured in Taiwan to VFC’s production standards, this lightweight nylon chamber maintains the strength needed for consistent operation while keeping mass extremely low to reduce strain on the bolt and nozzle assembly. Because the chamber directly influences BB alignment and gas sealing, replacing a worn unit immediately resolves issues such as misfeeds, erratic FPS, or inconsistent cycling—returning your rifle to factory-intended performance.

Designed for classic and modern AR/M4 GBB platforms

Built for AR and M4 series rifles, this chamber is compatible with a wide range of classic models including the M733, M727, M16A2, XM177E2, and the VFC SR16E3 (part number 07 14). Its precise tolerances make it ideal for restoring older replicas, tuning vintage builds, or maintaining long-owned rifles that have begun to show signs of wear. Whether used in gas or CO2 powered systems, the chamber provides reliable feeding and sealing performance across different setups, giving players flexibility throughout the year.

Lightweight durability with factory-spec alignment

Weighing just 0.01 kg and measuring 30 mm in length, the nylon construction offers an ideal balance of durability and low weight. The chamber ensures smooth BB guidance, consistent pressure sealing, and dependable cycling behavior—core factors that affect accuracy, range, and shot-to-shot consistency. For players looking for authentic VFC internal parts, OEM chamber replacements, or components that maintain realistic GBBR operation, this chamber delivers a precise, ready-to-install solution built to factory specifications.
