Firearm Maintenance: SKS Cleaning, Part 2/4


Continuing with the Brownells SKS Maintenance
series with Disassembly covered in the Previous video now we’re ready For cleaning
In part one we referenced the Importance of properly cleaning Your SKS when you’ve been
using Corrosive ammo So before cleaning a quick Explanation is
in order Corrosive ammunition is referring To the preservative
chemicals Used in the primers of almost all Military surplus ammunition fired Through
these rifles When ignited these chemicals Deposit potassium
chloride or Sodium chloride These harmless alkalis when Exposed to hydrogen
and oxygen In the ambient humidity form an Acid resulting in the rusting and Pitting
of the metal surfaces Therefore the best way to clean The piston
bolt and its Components is to drop them into A tub of water for a couple of Minutes to
dissolve any salts Followed by a brushing Ensure the gas port is not clogged And that
the piston extension can Move freely in its recess
Remove the parts and dry them Thoroughly using a rag or a blow Dryer if you have one
Note if you’re uneasy about using Water on your rifle water based Solvents like Ed’s
Red or Shooter’s Choice Aqua Clean may be a Better alternative
With these parts now cleaned and Dried use a brush to remove Carbon buildup from the
piston Extension and its spring Once that is complete spray out The gas cylinder
Check that the piston will slide Freely through it
If not you will need to clean it out Further with your brush
Next use a nylon brush to clean The recoil spring assembly Magazine assembly and trigger
Mechanism You may also need to use a cotton Swab to
reach some areas Once the caked on carbon is Removed spray
the mechanisms Out with a spray cleaner like TCE And dry them with a cloth
Now we’ll move to the bolt and Carrier If using non-corrosive ammo you Can spray
the parts and give them A good brushing Make sure that the rail cuts on The carrier
and the recoil spring Recess are free of debris The firing pin must move freely in The bolt
so be sure to check this It may require cotton swabs to Clean out the
firing pin channel Then wipe the bolt and carrier off Before moving on to inspect the
Firing pin extractor and extractor Spring Excessive carbon on these parts Can impede
their function so Clean and dry them well Note if you are using corrosive Ammo you’ll
have to clean the Stripped bolt to remove the Buildup by dropping it in water to Soak
for a couple of minutes and Drying it thoroughly Lastly we’ll clean the bore and Chamber
You will need a cleaning rod the Correct caliber bore brush jag Patches and a suitable solvent
Again if you’ve been firing Corrosive ammo you’d first need To run a bit of water down
the Bore to rinse out any salts and Give it a few passes with a brush Before proceeding
to the normal Cleaning process that we’ll cover Now
To start run a solvent-soaked Patch through the bore and allow It to sit for the recommended
Amount of time by the Manufacturer Next we’ll switch to a bore brush And run
it back and forth through The bore to scrub out any fouling Making sure to make ten to
Fifteen complete strokes Then we’ll switch back to our jag And follow
up with a few solvent Soaked patches to wipe out the Bore
Run a clean dry patch through to Check your progress
If the patch still shows signs of Fouling you’ll want to repeat the Procedure until
all of the fouling is Removed With that the gun is now Completely cleaned
and ready for Lubrication and we’ll be going Over that in part 3
