Specs
My first 300 Blackout and I am SUPER HAPPY with the purchase because I already have a MCX Virtus 11.5" 556. So all I had to do was change the upper if I wanted to shoot the 300 BLK. The price was the cheapest that I found after tax and shipping. If there was a MCX Virtus 300 BLK 6.5 Upper, I would buy that as well.
