I have a Mak90 that I have had in my safe since the 90s when I bought it at Roses Department Store for $199.95 and with all the hoopla and panic going on right now, I am taking a good look at it. It has the thumbhole stock that everyone hates, but what can a guy do, right? Anyway, what I need to know is how can I tell by just looking at it without removing the stock if it's a stamped or milled receiver and if it's a slant cut or straight cut receiver? Do any of you guys have any pics that I can compare mine with? thanks Wanna kill these ads? We can help!
