Specna Arms SA-J20 VAPOR GBB Submachine Gun - Black

The Specna Arms SA-J20 VAPOR is a gas-powered GBB submachine gun developed in cooperation with Well Pro. The model is based on the Russian PPK-20 submachine gun, designed as a compact and easily controllable platform especially suited for close-range engagements. Its compact dimensions, realistic blowback operation, and metal-heavy construction make it an excellent choice for CQB gameplay.

The construction combines aluminum, steel, and reinforced polymer, providing both realistic handling and solid durability during active use. Aluminum components include the outer barrel, charging handle, bolt, magazine housing, and ambidextrous fire selectors. Steel is used in critical structural components such as the receiver, muzzle device, top cover, recoil spring guide, and reinforced front section of the hop-up housing.

The polymer M-LOK handguard features RIS rails on the top and bottom for mounting accessories such as lights, lasers, optics, or vertical grips. The adjustable telescopic stock allows the replica to be adapted for different users and play styles. Compact dimensions make the platform particularly effective in CQB environments and tight spaces.

The rifle features a functional blowback system that delivers noticeable recoil and enhances shooting realism. A factory-installed NPAS system allows the user to fine-tune power output to suit different needs. Ambidextrous fire selectors also improve usability for left-handed players.
