I own both the 5.56 nato and 7.62 nato. They are great rifles and probably my favorites. Good luck on your quest good sir. I picked one up a few years ago from a member on here. Both are awesome handy little get it done rifles.
I own one great shooter. 10mm is a little scarce at the moment to get into. But if you have others is a awesome gun and handles the recoil really well. Grip is a little aggressive but I like it.
