Double Bell Green Gas Hi-Capa 5.1 Gas Blowback Airsoft Pistol, Black

The Double Bell 782 is a Hi-Capa 5.1 gas blowback pistol built for players who want a realistic sidearm without the full-metal weight. It pairs a metal slide and outer barrel with a polymer lower frame, which keeps it light while still delivering the reciprocating slide action and recoil you expect from a GBB. It fits in a holster or thigh rig without bulk.

Velocity and where it works. Rated 300–340 FPS on 0.20g BBs. That's a standard sidearm envelope: it clears most outdoor pistol limits and sits comfortably inside typical indoor CQB caps. As with any GBB, actual velocity shifts with gas pressure and temperature—expect lower numbers in cold weather. Chrono with your own BBs before your first game.

The Hi-Capa platform. This follows Tokyo Marui Hi-Capa 5.1 internal dimensions, so the aftermarket support is deep. Inner barrels, buckings, recoil springs, and hop-up parts are all off-the-shelf. A common first upgrade path is a tightbore inner barrel and an upgraded bucking for better consistency, followed by a lighter recoil spring if you want faster slide recovery. You do not need to do any of this for the gun to function, but the upgrade ecosystem is genuinely one of the best in airsoft.

What you get and what you'll need. The box includes the pistol, a 25-round gas magazine (model 789J), a cleaning rod, and a spare loading nozzle. Green gas and BBs are not included. GBB magazines hold gas and BBs together, so each mag is a single shot capacity—plan on three to five mags for a typical game. The magazine itself is the gas reservoir, so you'll need a green gas canister and a quick-fill adapter.

Quirks to know. GBBs are sensitive to cold; below roughly 50°F (10°C), cycle rates drop and you may experience feeding issues. Some players run a magazine heater or swap to CO2 with a compatible adapter for cold-weather play. The polymer frame is lighter than an all-metal build, which helps with all-day carry, but it also means the gun feels less "hefty" on the draw. If you want full metal, look at a different platform.

What this is not for. This is a sidearm. It is not a primary rifle, and it is not a long-range solution. The 25-round capacity means frequent reloads in sustained firefights. If your game demands high capacity or long-distance accuracy, run an AEG as your primary and keep this as a backup.

Includes federally mandated blaze orange muzzle tip.
