AGM 300rnd High-Cap Magazine for MP40/STEN AEGs

If you need large capacity magazines for your STEN or MP40 AEG, this is the choice! The AGM 300rnd High-Cap Magazine is compatible with AGM's STEN gun and MP40 AEGs, holding 300 BBs with a wheel-wound design. The external shell of the magazine is constructed from steel for an authentic feel and has reinforcement ribs on either side, matching the real thing perfectly. This magazine is a high-cap, meaning it holds an impressive 300 rounds and is ideal for those who want the maximum BBs to magazine ratio. To load the mag, open the fill port at the top, pour in your BBs and then tension the spring with the winding wheel on the bottom.
