Hello and thank you for the add! I am not new to the AR line but I will soon be new to the big bore line. I have settled on the .450bm due to ammo availability and the fact you can walk into academy and grab some without having to order it. Anyway, the point of this post is to ask a question. I was researching and came across Moriarti Arms. Has anyone had any person experience with them?

The build I am looking at comes with a KAK barrel. From my research and person use of KAK products it seems like a good barrel choice. The second thing is what is the difference in performance between a 16 inch and an 18 inch barrel?

Thanks!
