Quick Build Ballistic Advantage 300 Blackout AR-15 Kit with Complete Free-Floated Upper Receiver (QB-4BA) - FREE SHIPPING
Building your own custom 300 Blackout AR-15 Rifle is a snap when you have all of the right parts. It's even easier when someone has already done the legwork to source all of the components, made sure they are of the highest quality and fit, BUILDS AND TESTS THE UPPER RECEIVER and then put them all into a nice little package for you and it's a complete no-brainer when they do all of that and then offer it to you at a price you cannot beat if you tried putting it all together yourself AND THEN offering to ship it all to you FOR FREE!
Well that's exactly what we have done and you're going to love it!
Just add your stripped lower receiver and mag and you're ready to go.
