CNC EON Hop-Up Chamber M4 / AR15 (V2) by Gate

The high-end CNC hop-up chamber GATE EON is an ideal upgrade for both AEG and HPA M4-based replicas where you want better long-range accuracy, tighter groupings, and consistent power. Its unique TDC (Top Down Centered) system ensures perfectly centered and even pressure on the hop-up nub, delivering a straight and stable BB trajectory every time. Precision CNC-machined from aluminum, it features an ergonomic rotary ring for precise pressure adjustment. The dimensional accuracy ensures consistent muzzle velocity without fluctuations and excellent air seal without the need for Teflon tape. The upgraded CNC POM C-clip barrel lock prevents rotation of the inner barrel and allows for a precise, secure fit. Fully compatible with the GATE PULSAR S HPA system and the GATE EON V2 gearbox. The chamber is designed to accept any type of nub (standard, Omega, M-nub, etc.) and offers a full adjustment range without deforming the bucking collar.
