Trying to build an AK based pistol and need to figure out which bolt/bolt carrier would work better for my purpose. So I have a few questions about the differences between them.
1.) On AK-74's that use a 5.45 bolt with a smaller diameter stem (the part that slides in to the hole in the bolt carrier) than those on 7.62 AKM bolts what is the diameter of the smaller stem? Also, what is the diameter of the hole for the firing pin on the 5.45 bolts?
2.) Are there any 5.56 bolts that are made for use with 22mm trunnions and 5.45 bolt carriers or are they all meant for use with 23mm trunnions and 7.62x39 bolt carriers?
3.) Are the bolt carriers for Saigas interchangeable with regular AK's or did Saiga make some changes to the bolt carrier to cause them to be incompatible with regular AK's? I know there are some differences with some of the Saiga bolts but I don't know if the bolt carrier itself is interchangeable with AK's from other countries.
Any help that you guys can provide would be greatly appreciated. Thanks.
