Yooper John's SKS - Battle rifle of many nations

SECTION  14:  In this section I will try to show the differences between the same part from different arsenals, years and countries. The only purpose of this page is to help make the collector aware that differences do occur and about anything could be possible. These are ALL from my personal observations and not from any books.

SKS RECEIVER DIFFERENCES

The various pictures below show the actual receivers and receiver covers from various makes and models of SKS's.  The commercial SKS model D and M could have either ones configuration depending on when they were converted or made. In some pictures you can also note the different type/size of the rear sight assembly.  Currently these are the only differences I have noticed. Some are only cosmetic, some have different stampings, some are shaped slightly different and some are just plain different.  NOTE:  Russian 1952 year SKS's seem to be the transition SKS as far as part changes go. Russia 1950 pictures applies to only the 1949-1952 (some 1952) Russian SKS.

Notice the cut out area on the early receivers (white arrow)

Note differences as illustrated above.

Russia 1950 applies to only the 1949-1952 (some 1952) Russian SKS.

The Russian 1955 is common to all makers other than late Chinese from approximately 1967 on. 

 

Note differences as illustrated above.

The Magazine catch appears to be fairly similar in all versions except for the modified 

SKS/AK models "D" and "M".

********* Note that your M or D could be of either variety depending on when it was made.  The ones below represent the ones that I have examined.

 

 

Notice the welded up area on the modified magazine catch on the SKS "M" model.

This SKS "D" model lacks any mechanism found in other catches NOTE the lack of parts or

area to put the parts in.  This Model "D" was made for and not modified for the AK style magazine. This is the later style

that used newly manufactured receivers.

 

 

 

The Trigger housing catch appears to be fairly similar in all versions.

Russia 1950 applies to only the 1949-1952 (some 1952) Russian SKS.

The Russian 1955 is common to all makers other than late Chinese from approximately 1967 on. 

 

This is what the Sheet Metal Receiver looks like in the stock

 

 

Different views of the front portion of the Stamped Sheet Metal Receiver.

 

 

Different views of the rear portion of the Stamped Sheet Metal Receiver.

Note area circled showing pins for the receiver cover, see below.

 

 

Different views of the bottom and side of the Stamped Sheet Metal Receiver.

The SKS below looks pretty normal, But it's NOT!  This one has a CAST Receiver.  Pictures compliments of OLDCARJUNKIE.

 

  

Notice the pin on the top left side of receiver.

 

 

Notice the pin on the top right side of receiver.

 

Check out the barrel attachment, short barrel lug and the rear sight lug.

 

Bottom view showing the 2 pins in the front of the receiver.

Top view showing the 2 receiver pins and D marked rear sight.

 

Side view showing the receiver, barrel lug and rear sight.

Top is regular milled receiver using a horizontally pinned barrel.

Bottom  is Cast receiver using 2 vertical pins attaching barrel.

Bottom view of the receivers.  Top is milled and bottom is cast...................what a difference!

 

View showing the machining done to the milled (top) compared to the cast (bottom) receiver.

Cast on the left and Milled on the right.

The Pictures below come from Ray Pizzino.  His gun "appears" to have a cast receiver and a very late bolt carrier.

       

Note porous appearance of the receiver.                                                                    Late D sight and note the stripper clip guide.

 

       

Note the bolt carrier finish and machining.  This gun has a screwed barrel lug!!  You would think it would be pinned, it is like the one above (oldcarjunkie).

Note the variations in the cut areas of the above SKS's using the AK magazines. Your M or D could be any of these.

 

 

View of the stock insert used for AK style magazines, NOTE the 2 variations shown above.

 

 

Note the area where the front magazine tang is positioned in order to hold the magazine in place on the receiver.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This "M" model used a military receiver where all markings were removed by milling the top half of the left side of the receiver and applying new markings.

 

 

 

        

    Note the differences in machining of the surfaces and grooves cut into the late Chinese cover.

Note:  This is NOT a stamped sheet metal cover!!  It was a late cover on a sheet metal receiver.

Some covers are even more crudely made in order to try and reduce manufacturing costs.
