Instruction manual for green gas-powered replica guns.

1. Keep your replica clean

After each game:

• Wipe the lock and the inside of the frame clean of dirt and green gas residue.

• Clean the barrel: wipe it with a cloth or stick with a little 100% silicone or isopropyl alcohol (IPA).

• Remove dust and sand with compressed air or a brush.

2. Lubrication – the most important part

What to use:

• 100% silicone (oil or spray) – for seals (O-rings), nozzles, magazines.

• Teflon or silicone grease – for bolt guides.

• DO NOT use automotive grease or mineral oils – they damage the rubber parts in the replica.

Where to lubricate (every 1–3 games):

• Magazine O-rings (on valves and inside).

• Blow-back unit nozzle O-ring.

• Bolt guides (thin layer!).

• Moving parts in the trigger mechanism (very sparingly).

3. Magazine service (key in GBB)

Magazines are the most common point of failure.

After each game:

• Clean the valves of dust and sand

• Put 1–2 drops of silicone into the gas inlet.

• Fill the magazines with gas with silicone at least once every few uses — it keeps the O-rings soft and tight

The gas used matters

• Green Gas – the most common and usually safe.

• Red Gas / Black Gas – not recommended for plastic replicas; they can damage them (too much pressure).

• In winter, you can use stronger gas, but only if the manufacturer allows it.

4. Regular technical inspection

Every 2–4 months (depending on how intensively you play):

• Disassemble the lock and check the condition of the nozzle and return spring.

• Check for cracks in the guides and on the outer barrel (a common problem in GBBs).

• Replace worn O-rings – they cost pennies and seal like new.

5. Common mistakes (avoid them!)

• Too much grease – slows down the lock and traps dirt.

• Lubricating metal, fast-moving parts with silicone – impairs performance.

• Firing with an empty tank – damages the valves.

• Leaving the magazine full for a long time – unnecessary pressure on the seals.

6. Storage:

• DO NOT leave magazines empty.

• Leave some gas (approx. 10–30% pressure).

This keeps the seals in good condition.

7. Storage of the replica

• Store at room temperature (gas does not tolerate extreme temperatures well).

• Avoid moisture – it can cause corrosion of steel components.

• Protect the lock and guides with a thin layer of grease if the replica is stored for a long time.
