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. This design choice simplifies the folding process but limits the ability to use traditional AK stocks without permanent modification.

Internally, the replica features a fire control group modeled after the Tokyo Marui AK design and includes an adjustable valve in the bolt carrier to regulate velocity. A notable feature is the hop-up adjustment, which is integrated into the barrel pin for access without tools. The disassembly process is straightforward, allowing for easy maintenance of the nozzle and inner barrel, though some factory screws are made of softer materials that can strip during maintenance. The internal components show consistent wear patterns over several thousand cycles, suggesting a functional level of durability for regular use.

Performance tests indicate that the replica operates with high gas efficiency, capable of firing multiple magazine loads on a single fill of propane. It maintains functionality in cooler temperatures, though the cycle rate slows as the thermometer drops. The recoil impulse provides a physical feedback that is both snappy and significant, while the accuracy at distances of one hundred feet remains consistent. Despite minor issues with magazine weight and the specific stock hinge design, the platform offers a unique option for users seeking a compact gas blowback replica with steel construction and out-of-the-box adjustability.
