$1,899
Folks, it's an AR-15

O.K. ... It's an AR-15 with a pink purple trigger.

For the same amount of money, you and your partner could purchase two (Yes, Two) rifles from Target Sports then use the other $500 to purchase ammo or spend $200 for better furniture from Brownell's then buy some ammo.
