I love this gun

I'm addicted I've been to the range 3x this week shot this gun yesterday omg I'm gonna purchase this really soon. Don't sleep on 5.56 ammo I love this place. I had a .22 now I'm ready for a nice hand gun and Ar.

My son is left handed so this gun is excellent since it works for left or right shooters. I plan to purchase another one soon.

My Favorite Rifle

I got this rifle as a recommendation and I'm so happy I listened. It has truly turned into my favorite rifle. Im amazed that the price is so low considering how awesome this firearm is. If you're thinking about it, stop, just go get it. You won't regret it.

Solid AR for the price

Picked this up at the recommendation of a friend, and it's a really awesome setup for the price. Sig really knocked it out of the park with this one in my opinion. 

Nice gun

The tread is a really nice AR that has tons of options for any shooter.
