Introduction
The SKS, a legendary rifle famend for its ruggedness and historic significance, typically leaves one thing to be desired with regards to its set off. The manufacturing unit set off, whereas practical, can typically be gritty, heavy, and inconsistent. This will negatively impression accuracy and total capturing enjoyment. Welcome to the fourth installment of our *OP SKS Gunsmith* sequence, the place we delve into the artwork of enhancing your SKS rifle.

This information will stroll you thru the steps of refining your SKS set off, reworking it right into a smoother and extra dependable mechanism. Whether or not you are a seasoned shooter or a newcomer to gunsmithing, this information goals to offer you the information and sensible steps needed to attain a vastly improved set off pull. We’ll discover methods that assist alleviate grittiness, scale back pull weight, and create a extra constant set off break.
This mission will contain some fundamental gunsmithing abilities and requires a methodical method. It’s a fantastic mission for these trying to enhance the general capturing expertise of their SKS rifle. You’ll need some particular instruments to finish the duty, which we’ll element within the following sections. Prepare to remodel your SKS’s set off from a practical element to a precision-enhancing function!
Security First

Examine the Journal
Make sure the journal is empty. In case your SKS has a removable journal, take away it.
Dry Hearth
Level the muzzle in a secure path, and pull the set off to confirm the firing pin falls and the hammer is launched.
Secure Course
At all times level the muzzle of the rifle in a secure path all through the whole course of, ideally in direction of a stable backstop in an space the place any unintentional discharge won’t trigger hurt.

Ear Safety
Loud noises can injury your listening to. Put on earplugs or earmuffs.

Disassembly for the Set off Group
Whereas the precise steps might fluctuate relying on the mannequin and modifications, we are going to deal with normal steering to get you began. Earlier than we dive into the set off work, you’ll need to take away the set off group. This typically requires some disassembly of the rifle.
First, make sure the rifle is unloaded and secure, as beforehand described.
Start by eradicating the inventory. This sometimes includes eradicating the inventory bolt or screws situated on the receiver’s rear, simply behind the receiver cowl. You would possibly have to take out the buttplate screws as properly, if they aren’t on the identical meeting. Watch out to not strip the screw threads.
As soon as the inventory is off, you may have entry to the set off group. The SKS set off group is a self-contained unit normally held in place by a cross pin or set off group pin or two. Relying in your particular mannequin, the set off group pin could also be inserted from both facet. Utilizing a punch of acceptable diameter (a pin punch set is really helpful), gently faucet the pin out, supporting the other facet to stop it from bending. Don’t hammer too exhausting, you wish to keep away from injury to the receiver or the set off group.
The set off group can now be faraway from the receiver. Take your time, and take note of how the components match collectively. Many freshmen make the error of shedding monitor of all of the little items. You’ll want to arrange all of the components in a manner that you would be able to simply bear in mind the order through which they got here from.
The Gunsmithing Course of: Refining the Set off
With the set off group eliminated and safely secured, we are able to start engaged on the set off itself. The objective is to clean the motion, scale back any grittiness, and lighten the pull weight, if desired. Keep in mind that any modification to the interior components of your SKS set off carries a danger, and in case you are not snug with this work, it might be finest to take your SKS to knowledgeable gunsmith.
Inspection and Cleansing
Earlier than starting any modification, rigorously examine all of the set off group parts for put on, injury, or any indicators of rust.

Eradicating any particles, grease, or oil. Think about using an ultrasonic cleaner for more practical cleansing.
Sprucing the Friction Factors
The important thing to a clean set off pull is decreasing friction between the shifting components. Establish the important thing friction factors throughout the set off group. This sometimes consists of the next:
- Set off Sear: The half that engages the hammer.
- Hammer Sear: The half that engages the set off and holds the hammer in place.
- Hammer Pivot: The world the place the hammer rotates.
- Set off Pivot: The world the place the set off rotates.
Use a small quantity of sprucing compound (reminiscent of Flitz or an analogous steel polish) on a felt bob or cotton swab. Rigorously polish the friction surfaces, taking care to not take away an excessive amount of materials. Work slowly and methodically.
Set off Modification (Elective)
For decreasing the set off pull weight, you’ve got a few choices. *Disclaimer: Lowering the burden of your set off might enhance the danger of unintentional discharges. At all times check rigorously after finishing any modifications. In case you are not snug with any a part of this course of, take your SKS to knowledgeable gunsmith.*

You possibly can typically enhance the set off by rigorously and sparingly sprucing or stoning the set off sear and hammer sear engagement surfaces. *Warning*: This modification requires superior abilities, information of firearm mechanisms, and an understanding of how the sear and hammer work together. Sprucing or stoning the fallacious surfaces can render the set off unsafe.
Reassembly and Lubrication
When you’re happy with the sprucing and any modifications, reassemble the set off group. Apply a small quantity of high-quality gun lubricant to all of the shifting components, specializing in the friction factors you polished. Use a light-weight, non-gumming lubricant.
Check and Re-Set up
Rigorously check the set off group for clean perform. Cycle the motion and make sure the hammer reliably falls when the set off is pulled. Confirm that the hammer is securely held by the sear. For those who’ve lightened the set off pull, make sure the set off resets reliably.
Reinstall the set off group into the receiver.
Reassembly into the Rifle
After you’ve labored on the set off, the following step includes reassembling the set off group into the receiver after which placing every thing again collectively.
Begin by rigorously aligning the set off group and inserting the set off group pin, ensuring it’s correctly seated. Be sure that the set off continues to be functioning accurately.
Reinstall the inventory, guaranteeing all screws or bolts are tightened correctly.
Testing and Verification
With the rifle reassembled, it’s time to check your work.
Perform Check
Carry out a perform test to make sure that the hammer falls reliably and the set off resets. Cycle the bolt and dry-fire the rifle a number of occasions.
Set off Pull Weight
Measure the set off pull weight with a set off pull gauge. Evaluate the consequence to the unique set off pull weight and make sure that the specified changes have been made.
Accuracy
To find out the extent to which these modifications have an effect on accuracy, conduct a capturing check on the vary.
