It's beast. Got it from Smith & Wesson
M&P15 PC
Cost is $2,095 including tax and shipping was free. Bullets are heavy. I shot two in the sky and neighbor came at me yelling. Shoots very loud.
It also lets you choose the cover so I chose black complete to make it look real.
I also got this one
the M&P15 - MOE - Black
Both are heavy like crazy. About 45 pounds I would say
