Airsoft Chay goes over the Well Pro PP-19-01 Vityaz GBB. This GBB is constructed with a focus on external durability, utilizing steel for the receiver, dust cover, and various functional pins. This choice of materials results in a weight of approximately five pounds and nine ounces, providing a feel similar to its firearm counterpart. Whilst the polymer handguards are solid and comfortable, the folding stock design departs from the authentic Vityaz system by using an AK-12 style locking mechanism.

Airsoft Chay considers the Maruyama MP9 GBB as the best airsoft MP9, praising its realistic, high-quality polymer externals and well-designed steel internal components. Key positive features include its comfortable handling, modern controls, and an easy-to-access hop-up.
