Having read a post about someone having difficulties cleaning the bore with the SKS cleaning rod being too short, it piqued my curiosity. I had seen the Russian SKS posters on the forum earlier depicting how to correctly assemble the cleaning gear, I thought I'd give it a try. Pictures below.
1. I found that you had to assemble the case/detent pin AND the cap onto the cleaning rod BEFORE putting on either the brush or the patch jag.
2. After inserting the cleaning tool into the bore, you lock the cap over the back of the sight/cleaning rod holder.
3. The cleaning tool JUST comes to the end of the rifling, as seen by the end of the patch. The patch stays on the jag and can be constantly used.
4. Running the cleaning rod back and forth with the desired cleaning tool attached, the rod is held captive in the bore by the cap until the cap is unlocked to either use a different tool or finish.
Having seen the directions on the poster, I found that it wasn't too complicated for even this old Jarhead, though without the pix, it might have been a tad difficult. No crayons
. This method has the plus of ensuring the crown isn't damaged. The down side is that the cleaning rod IS too short to be used the way MOST of us were taught in the Military, that is to clean from the chamber end so as to not touch the crown. Weapons like the Garand, M1 Carbine or M14 have to be cleaned from the muzzle end and some newer military rod kits come with a plastic rod guide to protect the crown, but they are a pain to use since they aren't captive.
I did find out that the standard USGI .30 cleaning rod has a VERY close thread pitch to the SKS cleaning rod and that you can use it as an extension. I hope this has been informative.
If this subject has been covered before, please excuse me since I didn't find it. Cheers, Bruce.
