The Gun Rocks crew go over the CYMA USP AEP if it is a good backup for airsoft games. The Cyma CM125 electric airsoft pistol, a replica of the widely used USP, comes with semi/full-auto functionality and a 200 fps output and an efficient hop-up unit. Its design features include an easy battery change, safety mechanism, thumb dial hop-up adjustment, durable polymer construction, and realistic detailing.
