Specna Arms PPK-20 SA-J20 VAPOR GBB submachine gun
The GBB gas submachine gun from Specna Arms, developed in collaboration with Well Pro, is a compact and rugged design ideal for CQB competition. The compact size, robust materials and realistic blow-back system make the model perfect both as a primary weapon in tight spaces and as a backup replica for a sniper or support shooter.
The construction is based on a combination of aluminium, steel and durable polymer, resulting in high durability and a realistic feel in use.
The SA-J20 VAPOR features made from aluminium:
- outer barrel
- dummy gas tube
- slide
- fire selector on both sides
- reloading handle
- magazine housing
steel was used to make:
- the discharge device
- barrel
- locking chamber cover
- fire selector levers
- magazine release
- barrel lock and hinge
- QD mount
- pins and screws
- reinforced barrel front (housing of the hop-up chamber)
- bipartite return spring guide
- return spring.
Made of polymer:
- handguard with M-LOK mount and RIS rail (at 12 o'clock and 6 o'clock)
- an adjustable (9 positions) buttstock finished with a rubber boot
- ergonomic, comfortable pistol grip
The model comes factory-equipped with an NPAS, allowing precise power adjustment and potentially affecting the blow-back recoil.
The model will suit players looking for a compact replica in the AK/PPK-20 system in Well Pro specification.
RIS rails on the handguard will allow expansion with additional accessories such as a torch, laser, red dot sight or vertical grip. The barrel equipped with a double-sided fire selector is a nod to left-handed players.
Moreover, an attentive user will notice the 6P73 and 9x19 calibre markings on the barrel, which will be appreciated by lovers of realism.
The smoothly functioning blow-back system gives a lot of satisfaction when shooting single or continuous fire. At the same time, it enhances realism by generating a clear recoil, which significantly increases the pleasure of use. The compact dimensions will allow operation in tight spaces.
