Airsoftology // Classic Army M4 ECR5 Review

Jonathan from Airsoftology reviews the Classic Army M4 ECR5 AEG.

Jonathan takes a look at the Classic Army ECR5 (Enhanced Combat Rifle) to see if this M4 is all looks, or if it has what it takes under the hood to keep up with its tacticool exterior.

The Classic Army M4 ECR5 has a CNC machined rail system and full length railed upper receiver with flip front and rear battle sights, ergonomic grip, and adjustable modstock. This sleek machine has plenty of space on its monolithic profile rails to take rail mounted scopes, lights, lasers, forward grips, grenade launchers, or other accessories. It comes with a quick detach short vertical grip for better stability and comfort. The enhanced carbine modstock can also fit a 9.6V large crane stock battery. This gun comes with 2x 300rd high capacity magazines.

Internally, the gun has a 9mm bearing gearbox, wire cut steel 21:1 ratio gears, inline mosfet protected trigger contacts, stainless steel bore up cylinder, aluminum bore-up cylinder head, metal spring guide with bearing, 6.03mm tightbore barrel, silver low resistance trigger wiring, and a quick change spring system. The wiring utilizes a low heat deans plug and comes with an adapter for tamiya connector batteries. It will shoot 375-400 fps using 0.20g BBs and 800-900 rpm using a 9.6V battery. The quick change spring system allows for fast and easy spring changes without having to go into the gearbox.
