There can be many reasons why one might be looking for blueprints or technical drawings of any particular gun or gun part. It can be for learning and educational purposes or to compare if their parts are within specs and many other reasons. If the legislation of your state or country allows, you can even make parts yourself (sounds like a nice project) to replace them on your guns or make custom ones.
So, if you search for gun blueprints online, you’ll probably find almost complete sets of AR-15 and 1911 pistol drawings. However, it is pretty hard to find anything AK-47 or “combloc” guns related. So considering the growing popularity of the AK-47 platform in the USA, I thought it would be interesting to our readers if I share the set of AK parts’ blueprints that I have gathered over the years.
I have to make a clear disclaimer first. I am posting these drawings solely for educational purposes and neither I nor The Firearm Blog have no guarantee concerning the precision of the drawings. If you decide to use these blueprint for any application, you’ll be doing it at your own risk. Also, make sure that your actions comply with your local legislation and don’t violate the laws.
I am posting the drawings by the source they are taken from. Note that all dimensions are in millimeters.
1) From a Russian book
The following two drawings are from a Russian book called “The Manufacturing of Automatic Firearms”, Vol.2 by L.T. Kreknin (“Производство Автоматического Оружия” часть 2, Л.Т. Крекнин). The book is about the manufacturing methods and techniques of firearms and all the processes are described using AK-74 parts as examples.
AK-74 front sight block
AK-74 gas block. This is usually referred to as a 90-degree gas block, because the gas port is drilled at a 90° angle in relation to the bore axis as opposed to the AK-47 gas port which is drilled at a 45° angle.
In that book, there are many more blueprints of non-finished parts in different stages of the manufacturing process. For example below is the drawing of AK-74 front trunnion forging.
2) AKM/AKMS Armorer’s Manual
Next set of drawings is from Russian AKM/AKMS armorer’s manual (1968). These are mainly drawings of small parts which were considered possible to be made at armorer’s level to replace the original ones. So they dedicated a chapter (or rather an appendix) to the mentioned drawings in the armorer’s manual. Besides the drawings, there is a lot more information concerning armorer level maintenance. If you understand Russian you can download the manual by clicking here.
AKM/AKMS hammer/trigger axis pin. Note that the drawings have their military codes and also a short technical description. In this case, it says that the material used is “steel 30ХРА” (roughly equal to AISI 4130 steel). It also says that the pin must be hardened to Rockwell hardness 42 to 50 and it should be parkerized.
Extractor retaining pin
Safety selector stop plate
Front sight drum
Front sight post
Magazine catch spring
Magazine catch axis pin
Thread protector
Recoil spring front guide
Recoil spring retainer
AKM grip
Firing pin retaining pin. Made of Russian steel 50 (close to AISI 1050), hardened to Rockwell 37-44 and parkerized.
Rivets. The first row in the table gives the dimensions of the trigger guard rivets, the second row tells the specs of rear trigger guard rivet and in the third row it says “2.5x8mm rivets”. These rivets are made of “steel 25” (similar to AISI 1025).
In this drawing, there are two sizes of swell head rivets. The drawing also says that these rivets must be hardened to Rockwell hardness 30-37.
Rear trunnion rivet. Steel 50 (AISI 1050), parkerized.
AKM magazine rear lug dimensions
Here are also a couple of AK cleaning kit tool drawings:
Next three are actually armorer tool drawings (from the same 1968 AKM/AKMS armorer’s manual):
Magazine straightening tool. This tool is used to fix dented metal magazines.
Gas tube straightening fixture
Dust cover straightening fixture
3) Drawings from miscellaneous sources
The third and last set of blueprints was found in a number of different online sources. These are mainly from Russian and European gun forums and websites. I am not sure about the original source of any of the drawings, however, judging from their appearance, they look to be scanned copies of original technical drawings. These are images with relatively large dimensions, so the description of each image will link to the original size file.
AK-47/AKM magazine. This one is made of several sheets which are misaligned. It is a bit annoying but still readable.
And as a bonus here is a very large (11800×4300) cutaway image of an AK-47. Again, you can download the full-size file by clicking on the link in the caption.
So there it is – my collection of AK blueprints. If you have something to add, please post in the comments. Let’s gather all the drawings here.
I hope you enjoyed this post and if you did, please also let me know about it in the comments. If this kind of post is something interesting for our readers, then I’ll make another one with other “combloc” guns’ blueprints (Makarov, SKS, Mosin-Nagant etc.).
