Seriously thinking of adding this to my toy collection. I especially like the aspect that you can just build/purchase the upper and mate it with your AR lower. The fact that Remington, etc. makes factory rounds for this caliber and are readily available is a big plus for me. Performance of this caliber is great with an advantage over an AK. The part that seals the deal for me is the ability to shoot subsonic and I believe use a 9mm or 45 can. I just need to get a 9 inch upper and it would be perfect!
Wondering if you've had any experience with this caliber?
