I have never used any with mine. My bro has a couple of TAPCO mags that have worked great in his.
What I really want is an easy way to convert it to take AK mags. I have alot of those.
I use the factory sights on mine and its fairly accurate under 100 yards. I love my AR but my Mini 14s are lots of fun.
Both Minis that I have are older models but I have thought about buying a new model to try out.
