Just got this in today, new in the box (post sample machine gun). It's called a TAC-9. It's a hybrid of an AR15 and a Tec-9, idk if thats a good combinationor a bad one. Has a tube upper, kind of like an AR lower, takes M16 FCG and takes Glock mags. Got a cheap folding stock for it. The gun looked interesting and was relatively inexpensive, thought it would be fun to try out. Hopefully it will run good.
