UDR-15 features newly designed skeletonizing with enhanced aesthetics. Equally at home on the field or in a competition, the UDR-15's high-efficiency gearbox provides superior performance in all settings. When APS set out to develop the Silver Edge gearbox, they wanted to bring to market an ultra-smooth, low amperage draw, ultra-reliable system with huge upgrade potential. The newest iteration of the Silver Edge gearbox named eSilver Edge takes everything that made the original great and improves upon it.
The newly developed advanced S.D.U (Super Dynamic Unit) chipset monitors the amperage drawn from shot to shot and will cut power to the gearbox if the current spikes too high before damage can be done to your gun.
To improve trigger performance, the eSilver Edge gearbox features a micro switch trigger that works together with the S.D.U. chipset for near-instantaneous trigger response (as fast as 0.02 seconds). When combined with a short stroked trigger, users can achieve an incredible semi-auto rate of fire.
