I am another who has several of both. I’ve noticed that I tend to take the ar’s to the range much more than the ak’s. I took an ak to the range this past weekend for the first time in a long time(years). So long that it took me a second or two to remember how to lock the mag in. But I had a ton of fun shooting it.
If I had to pick though, I would go with the ar. Ton’s of fun and I have never had a problem with them . Not to mention accessories are very easy to find. Common things like mags tend to be cheaper also.
Can’t go wrong with either. But after years of shooting both, I’ve become more of an ar guy.
