So, in the next month I'm buying an AK-47. I've had one in the past, a WASR Underfolder. I know WASRs are lower end, but I never had an issue, I only sold it cause I didn't care for the folding stock. I've been thinking i'm going to buy a fixed stock WASR, but my cousin offered to sell me his Lancaster Arms for $500. My first question is, how many parts are interchangable between the two, and how reliable are the Lancasters? My second question is about magazines. What are the best (most reliable), steel mags?I don't like plastic...I have lots ammo, and want to get lots of mags to load up. Thanks.
