Building your own custom .308 AR-10 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 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!
