The Newly improved G3 gearbox developed under collaboration between Matrix and S&T offers the same features found in the G2 series such as a microswitch trigger, improved steel gears, full steel teeth piston, and aluminum cylinder. New to the G3 series gearboxes is an improved QD spring system which makes it even easier to swap to different strength springs without disassembly. The inline MOSFET features over discharge protection and the electric trigger features a magnetic sensor for improved responsiveness.

Patterned after the original ArmaLite AR-15, Colt rifles have been in the hands of the US Military as well as many civilian enthusiasts since the adoption of the M16 combat rifle. Through years of hard use and first hand feedback to improve and evolve the weapon platform, the Colt M4 and M16 has risen to be one of the most popular and trusted combat rifles around the world.

"Cybergun Licensed Colt Sportsline M4 AEG Rifle w/ G3 Micro-Switch Gearbox (Model: Black / Keymod 10")

Works well. Put a 11.1v LiPo and a 6.03 TBB on it and it'll beam the BBs across the field. Works flawlessly. Good range. Shooting with .30s, I'm hitting around 350-360fps. Accurate. Added a new motor and this thing just works.

"(MODEL: M4 SBR W/ 8" QUADRAIL / TAN) - Great entry level weapon for air softers. External parts are pretty solid with the quality of material. Internal components may be on the cheaper side but still durable enough to last some time before attempting upgrades. Would recommend getting as a first timer or as a second back up weapon.
