If you can’t aim your target, check your rifle scope. This article will tell you how to repair the Gamo rifle scope in 5 steps. Get the tutorial right now!
The rifle scope limits the vertical and horizontal offset. Therefore, the mark must be in the so-called operating range of regulation.
If the mark is outside the operating range of regulation, then the spring does not work normally. After firing, the mark may move, which leads to a deterioration in the middle point of impact.
So, you need to know how to repair the Gamo rifle scope to get your weapon working again soon. Keep tracking our effective step-by-step tutorials!

How To Repair Gamo Rifle Scope?
In general terms, this article will help you understand the structure of optical sights, learn how to disassemble them, and carry out the simplest repair work.
DIY Sight Repair Procedure
Gamo Air Gun Scope LC4X32
The time has come to study the fastening of the base units of the optical sight. Please note that this is a fragile device, so you need to disassemble it with utmost care.
It starts to mess around after about one and a half thousand shots. To tighten the mounting screws to prevent future problems, watch out for horizontal guidance.
You will find that a sealant is attached to the lenses. According to our instructions, having disassembled the scope, you reach the ring nut holding the crosspiece.
Further, the procedure is as follows:
- Expressing the cassette (do not lose the pressure spring);
- Unscrewing the front nut, lens, and guide screws (2 pcs.);
- Removing the adjustment lenses from the inner cylinder. You must do this carefully, without giving the cylinder a vertical position;
- Remembering the location of the lenses;
If you can not unscrew the retaining ring at the trim lens, you will have to lubricate the thread with a sealant. After waiting for drying, assemble the entire structure in reverse order.
You will inevitably encounter a pressure spring in repair actions, which you need to save and ensure its functionality.
A little advice: you can unscrew the nuts with sharp-pointed tweezers. You should place unscrewed screws and nuts on a sealant.
You must push the repaired structure together with the spring back into the pipe. It is a rather laborious process. One end of the spring should end with teeth, and the other should be completely smooth.
If there is chipping, you must sand at the second end of the spring. Try to install the spring in the central part of the sight, between the holes for the adjustment drums. Push the pipe into the cassette with the assembled lenses while holding the spring through the holes.

Step 1: Dismantling The Optical Sight
Before disassembling the scope, ensure you have the necessary tools and accessories.
You will need:
- repair kit (set of flat screwdrivers);
- inexpensive transparent sealant (no solvents);
- cotton swabs;
- a clean cotton cloth;
- jars (for storing small bolts);
How to process?
- First, you have to unscrew the lenses (back/front).
- Screw the adjusting drums in until they stop.
- Unscrew them together with the pressure washers.
- Unscrew the push and lock bolts.
- Gently extrude the cassette containing the adjustment lens.
Localize the lens-reversing system in the remaining segment of the tube. Then unscrew it.
Assemble the structure in reverse order. Pay attention to the smudged lenses.
Should not touch lenses with fingers. If you have touched them, wipe them with one-way movements.

Step 2: Sight Lubrication
Not all parts and assemblies of an optical sight need lubrication. And even more precisely – only rings need it. Getting grease on the lens surface is highly undesirable.
For the lubrication procedure, you will need:
- alignment control rods;
- abrasive lapping paste;
- tool (torque screwdrivers, keys, and levels);
- locking device for threaded connections.
The manufacturer uses aluminum, steel, and titanium rings to mount the sight. After lubricating them, set the scope so that the nuts are on the other side of the receiver port and bolt handle.
Step 3: Optical Sight Illumination Repair

The basis of the reticle glow is an LED lamp. It does not receive energy directly from the battery but through the stabilizer. With the check of the stabilizer, you need to start the repair activity.
Having disassembled the microscopic power supply, take a closer look at the ballast resistor (capacitor). If the resistor is burnt out, you must replace it.
Sometimes the diodes in the rectifier also burn out. You should also check them. A third potential problem is low impedance current limiting resistors.

Step 4: Eliminating The Displacement Of The Aiming Mark
Manufacturers use a luminous aiming mark with brightness control in modern optics. The backlight of the stamp should turn off automatically after a certain time.
It saves battery power as many shooters forget to disconnect the battery. In general, aiming marks are of the following types:
You need to adjust the mark by turning the drum and focusing on the number of clicks. The offset scale varies depending on the scope model and manufacturer.
Having found a displacement of the mark, it is worth investigating the scope’s mount. Have you done everything correctly? Correct mounting guarantees a long service life for your aiming system. It is not worth saving by purchasing cheap mounts. It is self-deception, leading to a loss of accuracy.
Step 5: Telescopic Sight Alignment

“Zeroing” the sight (alignment) is the process of converting the mechanical and optical axes. The need for adjustment arises after purchasing a new sight.
The shooter is not yet sure of the correct range set by the correction drums. To reduce repair work frequency, protect your scope from bad weather: heat, humidity, and direct sunlight.
Cover the lenses with caps, avoid mechanical damage, and contact with the lenses of harmful substances (lubricants, alcohol solutions). Check the internal mountings periodically every 1000-1500 shots.

The frequently asked questions below will help you understand more about rifle scopes.
What Is Inside A Scope?
- A bigger objective lens in the front lets light into the scope body.
- An ocular lens at the back focuses that light on the shooter’s eye.
- The ocular, magnification, focus, and objective lenses go from the eyepiece to the scope’s back end.
How Do Rifle Scopes Work?
The objective lens is positioned in front of the user in the tube. This lens feeds light to the erector lens, flips the picture, sends it to the magnifying lens, and magnifies the image as the name says. Light flows from there to the ocular lens, which is closest to the user’s eye.
How Much Does A New Gamo Rifle Scope Cost?
A new Gamo rifle scope like Gamo Air Gun Scope LC4X32 costs under $50.
We hope the above guide has helped you know how to repair Gamo rifle scope. Just work gently on it to avoid breaking components and remember their order to reassemble them correctly. Good luck!
