What would be your preference. I own a few ak-47's and a few ar-15's. I've already got a bunch of cheap to shoot surplus 5.45 ammo with no gun to shoot it in. I'm leaning towards the upper for a couple of reasons. I think it's a more accurate platform then the ak, and I actually think it will be easier to clean and maintain. Of course the downsides are reliability and it appears mags can be a challenge to get for both platforms. Love to get some other peoples opinions. Wanna kill these ads? We can help!
