If anyone is looking for a 10" Stainless 1/8 300BO, I have a bunch of barrel kits in stock. Only for 450Bushmaster.net folks, $225 shipped for the barrel, CA gas block and pistol tube. $90 below what they would retail for if we sold this kit on the website.
I of course have complete 300BO uppers too if you are not a builder. http://www.carbonarms.us/AR-15-Uppers-a ... upper.html
Just drop me a PM if you need a barrel.
