A gas M4 burns through magazines faster than most new GBBR owners expect, and the LM4D is no exception — sustained fire empties a magazine quickly, and refilling gas mid-game is slow. Carrying a set of spare magazines is what turns the LM4D from a range toy into a viable skirmish primary. This is the official KWA AGM spare, built to the same standard as the magazine supplied with the rifle.
The 40-round capacity is a useful balance — enough rounds to stay in a firefight without the bulk and weight of a true high-cap, and a realistic mid-cap feel that suits milsim play. The gas reservoir is sized to comfortably cycle the full BB load on a single fill in normal conditions.
Construction is full metal, matching the LM4D rifle's build quality. The metal body survives the drops and knocks of skirmish use far better than polymer-bodied mags, and the weight adds to the realistic handling of the rifle. The magazine works directly with the LM4D's NPAS-equipped gas system.
Compatible specifically with the KWA LM4D GBBR. Verify against your rifle before buying spares — KWA GBBR magazines are platform-specific and don't cross over to other M4 GBBR systems like the Marui MWS or VFC.
