Straight Sigma Triggers from Prometheus for M4 AEGs are available at Airsoft Atlanta now... "The new Prometheus Straight Sigma Trigger made for standard M4 AEG airsoft guns. Red, Gold, Silver, and Black colors available. The straight trigger that matches stylish hand guards and frames, sharp design. It consists of two parts, a base part and a trigger pad, easy to incorporate, and easy to exchange to other colors once installed (removes with a small allen set screw). This trigger only works on M4 AEGs. Compatible with all "standard" M4/M16 guns from most major airsoft companies (Tokyo Marui compatible).

By optimizing the contact with the fingers by dropping the corner larger than our 'M16 custom trigger', it became possible to correspond to sniper as well. Also, by setting the total length longer than the usual trigger, it makes it easier to carry out continuous fire with a finger on the trigger guard.

The straight trigger has a good feeling for match style shooters. A better trigger response for CQB and faster game play.

Very high quality, polished metal, and made in Japan from Prometheus."
