AR9mm complete pistol upper Karri's guns

[dok]

I ordered one of these and i have to say it was by far the best customer service ever, emails prompt and going above and beyond to make a customer happy. When i receive it later in the week, I'll give a range report. No tax and free shipping made it the lowest i could find.
