Just got back from a mule deer hunt in Northern Arizona. My good friend was using a 6.8 Bushmaster upper with C products 5 round mags. We were stopped by an Arizona Game & Fish Officer and he wanted to inspect my friends mags to make sure they only would take 5 rounds. Well, he tried to push in a 6th round into the first 2 mags ~ no go. But on the third, he FORCED a 6th round into it! I'll bet the weapon wouldn't function with that mag in that condition! So, if you have to use 5 round mahs, make sure that they will only 5 rounds!
I think this guy was a jerk. A young officer, he told my friend NOT to use the mag. So, we went back to camp & put it up. I checked all of my C-Products mag 5 rounders, and they all passed. I was not using my 6.8 as I was given a McMillan custom bolt gun to use on this hunt. Boy, what a beauty it is! And in 270 Winchester to boot! I think it is a one off that they accidentally made instead of a 270 WSM. Helps to know Kelly McMillan!
