Complete AEGs from APS that have the Silver Edge Gearbox are available at Evike.com. Matt gives us the highlights of this series... "The APS Silver Edge M4 Airsoft AEG Rifle Series comes from the factory decked out with a metal Keymod style rail system, a full metal receiver, retractable stock tube, APS Rhino flip-up sights, and APS' new Silver Edge gearbox.

The full metal receiver is coated with a matte black finish and features stamped trademarks for a realistic look and feel. The full length 20mm top rail is great for any type of optics you decide to use and the 10" Keymod style rail comes complete with 3 additional accessory rails for lights, lasers, vertical grip, and other tactical add-ons. A retractable crane stock finishes off the rear of the gun while an aggressive mock compensator finishes off the front.

The all new APS Silver Edge Gearbox utilizes a unique polishing technique to remove burrs and surface imperfections from the gearbox shell. This polishing leads to an incredibly smooth and even finish that will reduce friction and lower the gearbox load. These improvements lead to a more efficient gearbox that will use less power, generate less wear, and allow for the smoothest cycle possible for enhanced performance as well as greatly extending the life of your gearbox.

• Precision Silver Edge gearbox
