Suggestions on receiver to buy? With or without trunion holes? I am wanting a fixed stock. Possibly a 5.45mm gun instead of 7.62
Atlantic Firearms has receivers for around $60. They are currently out of stock but they will have more soon. With our Without trunnion holes doesn't matter. Typically with holes will cost more so save your money and go without. Either way, in the class, you will learn methods to drill trunnion holes.
What is important is you select the correct receiver for caliber AKM 7.62 or AK74 5.45. NO 5.56, not building those for number of reasons.
If you are wanting to build a side folder using the metal triangle stock or composite stock you will have to by the receiver for the side folder. Side folder trunnion and stock will cost about $200 more in parts. Magpul Zhukov, Tapco, and other aftermarket folding stocks are made for use with standard fixed stock receiver. Price and quality vary greatly.
Polish Tantals are not interchangeable and we are not building them in these classes as of yet.
If you have any questions or doubts please PM me before buying.
