This is the 18" mossberg tactical AR. It's a fun little .22 with not much purpose but it's a good snake gun and I'll be bringing it back to Wyoming to get some wabbits (they're freaking huge up there).
Anyway, a lot of people don't like the idea of a .22 calibur AR. I didn't myself but as I said, it's still a fun weapon.
I like that it has an extra 2". May or may not be doing some threading. As you see in the video there's virtually no kick so that's good. Still a .22 and I'll be getting a .223 as soon as I find it but glad I got this one for free.
