Description
The ACE 1 Arms HPA AR/M4 Airsoft Rifle takes the familiar AR/M4 layout and pairs it with a high pressure air setup. Trigger control is handled by an electronic trigger unit, and the rifle is built for semi-automatic fire only, so each shot is a separate trigger press rather than a burst or full-auto string.
Listed under the Mosfet category, the model’s control electronics are central to how it shoots. The ETU manages the firing sequence electronically rather than through a mechanical contact set, and it is the part of the specification a buyer will want to check first.
As an HPA model from ACE 1 Arms, it is designed to run from a high pressure air supply, so build the rest of your kit around that air feed.
