1/16” pin punch
8oz ball peen hammer. (Nothing larger should be required!)
Set of needle files.
Shelf bracket (10-12” approx.)
Scribe or utility knife blade
2” x 4” scrap lumber.
Oil. (NOT WD40)
An occasional spare set of hands.
1) ALWAYS ASSUME THE GUN IS LOADED! Remove the magazine, check the action and verify the chamber is empty. Read through all of these steps before attempting this procedure. If you don’t understand something or don’t feel comfortable doing this mod to your gun, STOP! I would also recommend taking a careful look at the gas tube, gas block, receiver and barrel before during and after this procedure. You should know what it looks like before you start so you KNOW how to get it all back together. Take notes and/or pictures with your digital camera.
2) Completely field strip the gun including removing the gas regulator and gas piston.
3) Take your flashlight and carefully look into the gas tube where the gas piston resides. You should see a hole in the gas block. Inside that hole is the top of the barrel. There SHOULD be 2, 3 or 4 holes visible in the top of the barrel. If you can only see one hole, or one hole and part of another one or two, then this procedure is what you are looking for. Continue to the next step.

NOTE 1: If you can see 2, 3 or 4 unobstructed holes then this modification is probably NOT what you need to stop FTEs in your gun. I suggest you get a paperclip and bend it in such a way as to make a tool for cleaning the gas ports in the barrel. Using a flashlight check the barrel often to see if you are dislodging residue from the gas ports. If you are lucky this is all you need to solve your FTE problems. Swab the barrel, reassemble and test fire.
NOTE 2: I had a lengthy conversation with Clyde from RAAC regarding this issue and my modification. RAAC is VERY concerned about this issue and is doing everything in their power to make it right. If you are having FTE issues with your Saiga, contact RAAC and see about getting your non-converted gun warranted. After talking with Clyde it is my understanding that 2, 3 and 4 port guns have been produced. The 2 port guns are supposed to have slightly larger diameter ports. (I will confirm/verify this in a separate post.) In any case, your guns should properly cycle all ammo. If you have only one port, or one and ‘some’ ports showing, this simple modification will get your gun working properly without having to deal with warranty repairs.
4) Remove the front hand guard and any other accessories you may have attached to the gas tube and/or gas block and barrel. (The front hand guard is held in place with a single machine screw from the bottom. (Sling mount.) The hand guard is removed by pushing it forward. (Towards the end of the barrel.)
The next step involves removing the two retaining pins that hold the gas block into the barrel. These are the only pins that need to be removed. DO NOT remove the pin that holds the barrel to the receiver (Directly below the rear sight.) The upper retaining pin (Between the gas tube and the barrel) also retains the spring-loaded locking pin for the gas pressure regulator. Be careful when removing this pin as not to loose the retainer or spring.
