Laylax announced recently about the new Wide Use EG Gear under their Prometheus brand. Here is a video showing more about it... "It is a gear set corresponding to the mechanical box for standard electric guns. It optimizes materials and processes more based on our existing product design know-how. Shapes and dimensions are also adjusted, and Tokyo Marui, KRYTAC, G&G, etc. are compatible with different shape mechanical boxes.

The number of latch teeth for preventing reverse rotation is set to 10, which contributes to the improvement of semi auto shooting response."
