What is the TAC-9?
Cooked up by the KWA development group, the TAC-9 is built for players who want style, customization and serious performance. Its look is inspired by retro tech, with clean, aggressive lines that stand out on the field.
Inside, a short-stroke piston gives a faster trigger response and a higher rate of fire with less wear on the internals, and the NS3 gas system delivers smooth, reliable power. Lefty? No problem: the selector, charging handle and magazine release are all ambidextrous.

How the TAC-9 works
The short-stroke piston
In a short-stroke system the piston travels a shorter distance each shot. That means a faster trigger response and a higher rate of fire, with less wear on your internals.
Combined with the NS3 gas system, the TAC-9 stays fast and efficient through long strings of fire.
The 1913 stock adapter
The rear of the TAC-9 uses a 1913-style stock plate. Rotate the stock or swap it for any 1913-compatible option to make the TAC-9 more compact or more stable.
Collapsed, the TAC-9 is 15.12 in long. Extended, it is 23.75 in.
Filling the TAC-9 magazine
Green gas is stored in the magazine. Each shot uses some of it to fire the BB and cycle the bolt.
- Hold the magazine upside down and the green gas can upside down and vertical.
- Press the can straight down onto the fill valve until the magazine stops taking gas.
- Pull down the follower and pour BBs through the front loading gate.
- Gas cools during long full-auto strings. Rotate magazines and let them warm up between games.
Hop-up, explained
Hop-up puts backspin on the BB so it lifts and flies flatter and farther. Too little and BBs drop early. Too much and they climb.
- Start with the hop-up at its lowest setting.
- Fire a few shots at a target at your usual distance.
- Add a little hop at a time until BBs fly flat before they drop.
- Back it off if BBs start to rise. Re-check whenever you change BB weight.
TAC-9 care and parts
- Put a drop of silicone oil on the magazine seals now and then to keep them sealing well.
- Store gas magazines in a cool, dry place and never in direct sunlight or a hot car.
- Check feed lips and seals before each game, and do not drop magazines on hard surfaces.
- Wipe the gun down after each game and keep the inner barrel and hop-up bucking clean.
- Use silicone oil only. Avoid petroleum lubricants on seals and rubber parts.
