Ace 1 Arms M16 MWS Gas Magazine (CNC-B)
Upgrade your gas blowback rifle's performance with the Ace 1 Arms M16 MWS Gas Magazine (CNC-B). Specifically engineered for the Tokyo Marui M4/M16 MWS GI platform, this premium magazine features an upgraded CNC-machined internal core housing (Version B) designed to maximize structural stiffness and eliminate gas leakage. With its heavy-duty external finish, low-resistance gas routers, and high-efficiency intake valves, it delivers a highly consistent muzzle velocity and crisp, reliable bolt cycling.
This magazine is not compatible with any CYMA MWS rifle as the magazine doesn't lock into the magwell.
When it comes to gas blowback rifles, your magazine isn't just an ammo holder—it is the engine that drives your system. The Ace 1 Arms M16 MWS Gas Magazine (CNC-B) is a premium, rugged power delivery system built specifically for the ultra-popular Tokyo Marui MWS M4/M16 GBBR series. Designed to outlast and outperform stock options, the "CNC-B" edition brings high-precision aerospace engineering straight to your tactical reload setups.
Precision CNC Internal Architecture & Leak Prevention
The defining characteristic of the CNC-B variant is its precision-machined internal gas reservoir block. Unlike standard cast-alloy reservoirs that can develop microscopic structural fissures or porous voids over time, this inner core is entirely CNC-routed from solid block stock. This structural rigidity eliminates shell flexing under high internal pressures, keeping your main gasket seals perfectly aligned even during rapid semi-automatic or full-auto strings on hot summer days.
Optimized Gas Router Gas Efficiency
Every aspect of the feed lip and exhaust valve geometry has been refined to interface flawlessly with the TM MWS hop-up chamber and nozzle assembly. The hardened polymer feed lips ensure smooth, jam-free BB feeding, while the custom-profiled rubber gas router creates an airtight seal against the cylinder nozzle. This tight seal ensures virtually zero wasted propellant, transferring 100% of the gas pressure straight into driving the heavy steel bolt backward for a sharper, more realistic recoil kick.
Key Technical Features:
-
Engineered for TM MWS System: Seamless mechanical drop-in compatibility with the Tokyo Marui MWS GBBR rifle series.
-
CNC-B Reinforcement Structure: Solid CNC-machined internal core blocks warping and stops structural gas leaks.
-
Realistic M16 GI Styling: Classic steel-grey tactical coating mimics standard military issue 30-round magazines.
-
High-Flow Output Valves: Delivers consistent volume per shot to maintain stable muzzle velocity (FPS).
-
Impact-Resistant Feed Lips: Durable composite feed lips withstand rugged tactical speed-reloads on hard surfaces.
Field & Maintenance Recommendations
The Ace 1 Arms MWS magazine is optimized for premium green gas or propane use. To maintain absolute airtight reliability, ensure the intake and exhaust valves receive a light drop of pure liquid silicone oil every 3–5 fill cycles. When storing your magazines long-term, always leave a small, residual amount of green gas inside the chamber to keep positive pressure against the rubber o-rings, preventing them from drying out or shrinking.
