900 Multi-Pump Air Rifle FAQs

How Do I Operate the 900?

1. Place the rifle on safety.
2. Pull back the bolt completely to seal the pump assembly.
3. Pump the rifle 1–10 times.
4. Load a BB or pellet (never load both at the same time).
5. Push the bolt forward.
6. Take off safety.
7. Aim and fire.

How Do I Use the Sights Correctly?

Align the front sight dot between the two dots on the rear sight. The target should be directly above the sight picture. Adjust the rear sight as needed, moving it in the direction your shots need to go. For example:

• If shooting too far left, adjust the sight to the right.
• If shooting too far high, adjust the sight downward.

How Do I Load and Shoot Pellets vs. BBs?

• Loading BBs:

  • Open the door on the left-hand side of the rifle.
  • Add ~50 BBs (do not overfill).
  • Tilt the rifle slightly upward when cocking to feed a BB to the magnetic tip of the bolt.

• Loading Pellets:

  • Ensure the BB magazine is empty or tilt the rifle downward to prevent a BB from loading.
  • Drop a pellet into the loading tray with the head facing forward. Push the bolt forward to seat it.
  • Use cross-locking tweezers if handling pellets is difficult.

What Should I Do If My Gun Isn’t Working or Is Faulty?

If your gun isn’t functioning, refer to the following:

• Faulty Seals:

  • If pumping doesn’t increase power, the seals may be faulty.
  • If air leaks out of the barrel or between pumps, the valve pin or intake check valve could be defective.
  • Do not attempt repairs yourself, it may void your warranty. Email [email protected] with your proof of purchase, and we’ll assist.

What Happens If I Over-Pump?

• Accidentally over-pumping once or twice is fine but consistently pumping more than 10 times can weaken the seals and shorten the gun’s lifespan. 
• If over-pumped, dry fire into a safe backstop until the remaining air is released.

What Should I Do If My 900 Isn’t Shooting Accurately?

• Use pellets, as they provide better accuracy than BBs.
• Clean the barrel but avoid oiling it unless storing the gun.
• Test various pellet brands, styles, and weights. Shoot groups of 10 to find the pellets that produce the smallest group size. Once identified, adjust your sights to center the groups on the bullseye.

What Should I Do If My 900 Is Leaking?

• Ensure the bolt is fully pulled back and the safety is on before pumping. Follow these steps:

  1. With the bolt in the open position and safety on, pull the pump handle down with steady pressure.
  2. Swing the handle forward until you hear it take in air, then return the handle to the starting position.

• Lubrication:

  • Use 10W, 20W, or 30W non-detergent automotive oil on the three pump lever hinges, foam wiper, and piston seal every 500 shots.
  • Avoid household or aerosol oils, as they may damage the rifle.

• Still Leaking?

  • Email [email protected] with a description of the issue, proof of purchase, and any other details. We’ll determine if it’s under warranty and how best to assist.

Can I Attach a Scope to the 900?

Yes, you can attach the 4×32 BDC rifle scope to the 900 Multi-Pump Air Rifle, but you’ll need to purchase dovetail rings separately. The 900 has an 11mm dovetail rail, so be sure your optic or scope rings are compatible with that type of rail. Large, heavy optics are not ideal for the 900.

How Do I lubricate / maintain my 900?

• Keep the exterior clean with a dry, clean cloth.
• Lightly oil the outer barrel shroud with something like Ballistol or Rem oil. Do not leave the exterior greasy! A very light film of oil is all it takes to protect.
• Clean the barrel with a patch soaked in Ballistol or Rem oil, follow with several dry patches. Push them through with a brass or aluminum rod, or use a patch puller. If you are storing your gun long term, run a lightly oiled patch through the barrel. Right before you resume use, run a couple of dry patches through.
• It is best to clean the barrel of the gun when it is brand new. The barrel usually doesn't need to be cleaned unless you notice a change in accuracy, or prefer to shoot through clean barrels. It often takes a few shots to establish consistent accuracy right after cleaning a barrel.
• Lubricate the pump pivot points and the pump foam wiper with a drop or two of non detergent motor oil. Most commonly available in 30wt and is usually found in the lawnmower section of hardware stores. Air tool oil is another good choice, but tends to be more expensive. Do not over oil, as this attracts more dirt. Wipe any excess oil over the surfaces of the pump linkage and pump tube to assist in rust protection. Again, a light film is all it takes to protect from rust.
