3.1. Initial Inspection
Upon unpacking, carefully inspect all components for any signs of damage. Ensure all included items are present as listed in Section 2. If any parts are missing or damaged, contact Lancer Tactical customer support immediately.
3.2. Scope Mounting
- Identify the 21.2 mm Picatinny rail located on top of the air gun receiver.
- Attach the scope rings to the Picatinny rail, ensuring they are securely fastened.
- Place the scope into the rings, ensuring proper eye relief and reticle alignment.

Figure 3.1: The Picatinny rail allows for easy mounting of the included scope or other optics.
3.3. Filling the Air Tank (PCP)
The T-REX is a Pre-Charged Pneumatic (PCP) air gun and requires an external air source (e.g., high-pressure hand pump, scuba tank, or compressor) to fill its 230CC air tank. Always use clean, dry compressed air. Do not use oxygen or any other gas.
- Ensure the air gun is unloaded and on 'SAFE'.
- Locate the fill port, typically covered by a dust cap, at the front of the air tank.
- Connect the provided fill probe to your air source hose.
- Insert the fill probe firmly into the air gun's fill port.
- Slowly open the valve on your air source to begin filling. Monitor the pressure gauge on the air gun or fill station. Do not exceed the maximum fill pressure (typically indicated on the air gun or in specifications).
- Once the desired pressure is reached, close the air source valve and slowly bleed the pressure from the hose before disconnecting the fill probe.
- Replace the dust cap on the fill port.

4. Operating Instructions
4.1. Loading Pellets
The T-REX PCP Air Gun uses .22 caliber (5.5mm) pellets. Always use high-quality, consistent pellets for best accuracy.
- Ensure the air gun is on 'SAFE' and pointed in a safe direction.
- Operate the bolt action to open the breech.
- Carefully insert a single .22 caliber pellet into the breech, ensuring the skirt of the pellet is fully seated.
- Close the bolt action firmly. The air gun is now loaded and cocked.
4.2. Safety Operation
The air gun is equipped with a manual safety mechanism. The safety lever is typically located near the trigger guard.
- 'SAFE' Position: When the safety is engaged, the trigger mechanism is blocked, preventing accidental discharge. The safety resistance can be adjusted from 1-6 Lbf.
- 'FIRE' Position: Disengage the safety only when you are ready to shoot and your target is acquired.
4.3. Firing the Air Gun
- With the air gun loaded and cocked, assume a stable shooting position.
- Aim at your target, ensuring proper sight alignment and picture.
- Disengage the safety (move to 'FIRE' position).
- Place your finger on the trigger and slowly apply pressure until the shot breaks. The trigger pull is adjustable between 2-5 Lbf.
- After firing, keep the air gun pointed in a safe direction until you are ready for the next shot or to unload.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your T-REX PCP Air Gun.
5.1. Barrel Cleaning
Clean the barrel periodically, especially after extended shooting sessions or if accuracy degrades.
- Ensure the air gun is unloaded and degassed (air tank empty).
- Use a cleaning rod with a patch holder and appropriate .22 caliber cleaning patches.
- Apply a small amount of air gun barrel cleaning solution to a patch.
- Push the patch through the barrel from the breech end (if possible) to the muzzle. Avoid pulling dirty patches back through the breech.
- Repeat with clean, dry patches until they come out clean.
5.2. General Care and Storage
- Wipe down the exterior of the air gun with a clean, dry cloth after each use to remove dirt, moisture, and fingerprints.
- Periodically apply a thin coat of silicone oil to metal parts to prevent corrosion. Avoid petroleum-based oils on seals.
- Store the air gun in a cool, dry place, ideally in a gun case, away from direct sunlight and extreme temperatures.
- For long-term storage, it is recommended to store PCP air guns with some pressure in the tank (e.g., 500-1000 PSI) to maintain seal integrity, but never fully empty or fully charged.
