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.
Package include:
- Cleaning rod
- Low-Cap Magazine
- Replica
- Allen key
- BBs speedloader
Blow Back Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting. | Yes |

| Muzzle velocity [FPS] It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second). 1 FPS = 0,3 m/s 1 J = 99 m/s 1 J = 326,7 FPS | 320 |
| Fire mode | Full-auto Semi-auto |
| Hop-Up Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy). | Yes |
