Classic Airsoft reviews the CYMA Colt XM177E2 AEG which comes equipped with a MOSFET. The AEG features a full metal version 2 gearbox with a MOSFET trigger and quick-change spring. The integrated carry handle has an A1 style rear sight adjustment, and the functioning bolt catch holds the dummy bolt open for easy hop-up adjustment. The buffer tube is an XM177 style with 2 positions, and the flash hider is styled like a moderator. This is wired to the handguard, which can accommodate a battery.
