I have a AK74 (Bulgarian ARSENAL) Parts set, just waiting to have a receiver slapped on it, but I have a slight dilemma. I plan on doing a do-it-yourself kind of job because I am new, and what better way to understand a rifle than to put it together myself. Anyway, I have been looking around for flat receivers, and the like, and I noticed that NO-ONE sells AK74 flat-receivers. Am I missing something? Anyway, I wanted to know if the flat AK47 receivers can work with my AK74? I know that the ak47 7.62x39 and the ak74 5.45x39.5 rounds are different, so is the mag and round size going to creat a problem when I put a AK74 mag into one of these receiver magwells? If any of you have any experience with these flats, and if I need to make any modifications to these, please let me know whats up. Any help would be greatly appreciated!
