USAirsoft got another compact AEG from Classic Army to review, the Classic Army AR4-SBR Light AEG Rifle. Mainly made of Nylon Fibre it has its own ECS system that you can program to fire a 3 or 5-round burst, motor protection, and low battery warning. It also has a quick spring change and comes with a 5-inch M-Lok Slot URX Rail. On paper it should be a good CQB game weapon, but according to USAirsoft it needs more work. Find out in the video below:
