What makes America great is you can own, carry, and shoot a piston rifle and it doesn't matter a lick what I think.

Let me know when a piston AR wins a National match or is competitive in 3-gun. Until then I will stick to my 16" AR with it's NP3 bolt/carrier that I've never had a failure in.

I’m not knockin’ impingement rifles, I just prefer a cool bolt and no sh*t where it eats.
