How the M11A1 works
Open bolt, high rate of fire
The M11A1 fires from an open-bolt system and KWA lists its full-auto rate of fire at 28+ rounds per second.
Long full-auto strings use gas quickly and cool the magazine. Carry spare magazines and let them warm up between games.
Which magazines to use
The M11A1 takes the M11A1 NS2 48-round magazine. One is included.
Filling a gas SMG magazine
Green gas is stored in the magazine, and 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 magazine fill valve until it stops taking gas.
- Load BBs, insert the magazine and you are ready.
- Gas cools as you shoot. Let magazines warm up between strings and keep them out of direct sunlight.
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.
M11A1 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.
