Pinned barrel stock?

[Greatguns]

Looking at buying this to go ahead and restore SKS #4. Brain is a little foggy being sick so wanted to run this by you guys to confirm this is a pinned barrel stock.  Seller says right at 9" between back of stock cavity to back of crossbolt. Which I believe is correct, IIRC.

Here is a picture of what I use for reference, yours looks like it is for screwed-in barrel:

I recognize that GB seller, he had the 24 million SKS complete rifle that he took apart and tried selling those pieces instead of the complete rifle awhile back posted in the Auctions section.

This guy is in Pittsburg, KS if that help in the ID of him.

Thanks for the pics.

[Shoot The Refurbs]

Yup, same seller. 

[owenj492]

Greatguns, that stock is for screwed-in barrel, I dug out my pinned-barrel SKS and took a picture of the stock area that is made for the pinned-barrel SKS:

I disassembled the rifle and took this picture for you:

[owenj492]

Yup, same seller. 

Yup, I saved his GB name to a text file for future reference so as to avoid buying from him, just my own standard to follow especially after his response after I contacted him about selling the pieces of the rifle.

I wonder if there were some stocks relieved originally for a threaded barrel, but before the crossbolt holes were machined out, they shifted to pinned barrels. Thus the cross bolt is set back for the pinned barrel but the RSB area was relieved for a threaded barrel.
I did measure from the back of the FCG catch to the back edge of the crossbolt on my one pinned barrel and it came right at 9" which is what the guy told me the gap was from the back of the action cavity to the crossbolt. So it was throwing me off.

Thanks for the pic BTW

Great photos Owen.

I'll use those as my standard reference from here on out.

I tried putting pinned-barrel SKS in a threaded barrel stock and there is a very small space at the cross-bolt causing the barreled receiver to move back and forth just a little bit, the pinned barrel stocks I found were on ebay, after I requested pictures to confirm.

[Greatguns]

Okay, my old fuddled brain is starting to work now. Here is what I am remembering.

1. Pinned barreled actions will "fit" into threaded stocks, but not the other way around.
2. Reason being, the crossbolt on a pinned barrel has to ride on the receiver itself. Whereas, on a threaded barrel the crossbolt rides on the locking collar which sets it 1/8"-3/16" further forward.
3. Given that, besides the relief cuts in the wood, the actual most important aspect of whether a stock is made for a pinned barrel or not is the dimension from the back of the action cavity to the back of the crossbolt.
4. SO, while the relief cuts in a stock specifically for a pinned barrel are a dead give away, they are not the only factor in play.

I need to check my DP because IIRC, the crossbolt was tight to the receiver relief cut, but the RSB inletting was straight.

[owenj492]

So I dug out my other pinned-barrel SKS and took this picture, notice how the area looks like it is for a screwed-in barrel but also notice the cross-bolt placement, it is forward a little bit unlike the cross-bolt in a screwed-in barrel stock....it is all about where that cross-bolt is placed.

[Greatguns]

Owen, if you don't mind, would you measure from the back edge of the crossbolt to the back of the inletting where the action drops down into?(where the tripper group latch slides down through.)

It should be about 8 7/8" whereas a threaded barrel should be about 9" +/- 1/16"

EDIT, I had my numbers off. I went and took down my long collar letter gun and it is right at 9" so, I adjusted my number above accordingly. Sorry, but the being sick is really messing with my brain this week.

Something else I noticed, the dimension from the crossbolt to the cutaway for the casing ejection area. In your first pic it is also the 1/8"-ish shorter. Tried to layer it highlighted and reupload it, but I couldn't figure it out.

Anyway, so by your latest pic we are seeing that not all pinned barrel stocks are step cut like in the first image and the distance definitely comes into play.

This also means, ultimately, that yes the stock I am looking at is indeed for a threaded barrel. Oh well.

Thanks again Owen

[Greatguns]

Hey Owen, I made another observation for the "straight line inletted stock"(that's what I'm calling them anyway). If you look at yours in you last pics with the tape, do you notice how it is 90 degree cut where the receiver ends and the barrel begins? I think that is a tell tale sign as well. The one in my OP is rounded to accomodate the collar. I found another stock on GB that is like yours and the dimension is correct.

Good stuff, gentleman.

Agreed, I also found this picture in my SKS folder to share, shows the difference where the barrel meets the receiver:

Yep, pics paint a thousand words
