Safety Tips to Keep in Mind While Cleaning

It may seem irrelevant or glaringly obvious, but always unload the gun before you begin cleaning it. Obey the 10 Commandments of Firearm Safety at all times and treat all firearms as if loaded.

Never point your rifle at another human being, including yourself and keep the gun under lock and key when not in use to prevent children from getting in contact with it.

Remember not to prod or pry off any part of the firearm. Gentle tapping is permissible.

To begin, make sure the safety is on as pulling the trigger could cause injury to the trigger group and point down range.

You then pull the magazine release tab on the underside and remove the contents or magazine.

Pull the bolt carrying charging handle all the way back and inspect the chamber by sight and touch. Close the fixed magazine.

Step 1: Preparation

Gather Your Tools

Cleaning the SKS thoroughly will take about 10-15 minutes so to speed up the process, it is best to gather your tools beforehand.

Find a clear space or high table away from children and pets, and find a sheet or newspapers to protect the chosen surface from grease marks and chemical stains.

This step has the additional advantage of protecting your gun from scratches.

Clean the Gun Surface

Some rough toweling and a superficial wipedown of the exterior of the gun is a good way to keep your own hands clean before the actual disassembly.

A recommended product for this process is the WD-40 which does not affect wood on the SKS.

Step 2: Disassembly

Removing the Receiver

The first time you´ll try to assemble a rifle by yourself, it will be quite tight.

Make sure the bolt is in a closed position and then proceed by turning the lever near the receiver cover counterclockwise.

Pull outward to remove the receiver and also take out the bolt, spring and bolt carrier. Clean with WD-40.

Removing the Trigger Group and Magazine

Prop the muzzle of the barrel on the floor and work on the indentation behind the trigger guard with a screwdriver till you hear a click or the trigger housing rises slightly.

Lift the trigger group swiftly out of the rifle and clean thoroughly with the WD-40 to remove grime and grease.

You can remove the magazine in the same way, by pulling it downward.

Remove the Barrel and Receiver From the Stock

Note that you must remove the magazine before the rifle stock. You can remove the barrel and the receiver from the stock by pulling upward on the receiver till you reach a 10-degree angle. At this point, you push the rifle front forward.

Once done, you can rotate the lever on the right side block clockwise to remove the gas tube and piston.

Lift and wiggle the gas tube assembly upward from the rear without applying excess force.

Remove the gas piston from the tube and clean. The operating rod can be removed by rotating the same lever at the 1 o'clock position, but you need to be careful as the rod is spring loaded and will launch itself once released.

Step 3: Cleaning

I’ve mentioned the use of WD-40 to clean the gun components, but if unavailable, you can substitute it with a suitable oil-based cleaner.

However, users have reported a water-ammonia mix to be an effective cleaning solution as well.

Clean the Barrel

Use a Phosphor bronze brush to scrub the barrel from the receiver end. If you start from the muzzle, you risk damaging the crown so you should avoid it.

Run the brush through the barrel 3 to 4 times and switch to a cleaner dampened swab tip for a more thorough cleansing. Do this and replace the swab tip till it comes out completely clean.

For the final cleaning, use a cleaning jag to go over the chamber and then use 2 dry patches, the second of which should come out clean.

Using Q tips and a toothbrush, clean the bolt carrier, the bolt and the cuts after which we can move on to the trigger group.

Clean the Trigger Group

Use the toothbrush bore cleaner and Q tips to remove any sign or grease and dirt. Apply 1-2 drops of oil to the spring where the hammer pivots and trigger connects.

Clean your recoil spring assembly and spring blocks in a similar manner.

Finally, take a clean patch and rub down all metal surfaces of the gun before reassembly.

Step 4: Reassembly

The reassembly is a simple process. You only have to put the parts back together in the exact reverse order you removed them.

Keep in mind, however, that the large screw going through the mid portion of the wooden stock is not to be tampered with.

Install Trigger Group

To reinstall the trigger group, set the rifle upside down on a flat bench with the safety on, position the group and straight arm push down until you hear it click into place. You can tap the trigger group lightly if it gets stuck in place.

Reset the Bolt

Turn the weapon over to insert the bolt, bolt face towards the chamber and the locking cuts upward, into the receiver.

Insert the bolt carrier into the receiver engaging the locking cuts on the bolt and the receiver rails. Now, install the recoil spring assembly into the cut in the bolt carrier with the locking clip forward.

Reinstall the Magazine

Push the front of the magazine in first and make sure it catches onto the bottom lip of the receiver.

Reinstall your receiver cover and push it all in. When seated properly, push the retaining pin and rotate it 90 degrees to lock it into place.
