KWA PTS RM4 CQB ERG Electric Recoil Airsoft Rifle – Magpul Edition for M4 Platforms

Built for serious CQB operators and dedicated field players alike, the KWA PTS RM4 CQB ERG delivers performance, durability, and a highly immersive shooting experience. Powered by KWA’s proprietary 3GX gearbox and outfitted with the patented Kinetic Feedback System (KFS), this electric recoil gun gives you the kick of a gas blowback rifle with the consistency of an AEG. Every trigger pull is clean and crisp, thanks to the mechanical/electric cutoff system that mimics real firearm function—perfect for players who want their gear to feel authentic and responsive.

Externally, this rifle is a head-turner. It features a full metal flat-top alloy upper receiver paired with a high-strength Magpul PTS polymer lower. Magpul’s signature MOE furniture—hand guard, pistol grip, stock, and rear MBUS sight—not only trims down unnecessary weight but also enhances ergonomics and maneuverability during intense play. Whether you're clearing rooms or holding corners, the lightweight profile and recoil realism make this rifle a CQB favorite.

Internally, KWA spares no detail. From the precision 2G bucking to the 6.05mm tight bore barrel, every shot counts. The RM4 also supports both 30 and 60-round firing modes, giving you the ability to train realistically or go full game-mode. Whether you're a weekend warrior or a hardcore MILSIM player, the RM4 CQB is a versatile beast designed to outperform on every level.
