Building your own rifle can be a hassle, we understand. You source parts from various companies to find the capabilities you want and then bemoan that the individual part you wanted is overpriced, but you would get a really good deal if you only added on six or seven other parts you don't need.
We're keeping this simple: You get an upper with a barrel without having to worry about quality control and performance at a great price.
Aero Precision is a renowned manufacturer of AR-15 parts. Their machining and tolerances are second to none without the inflated brand name costs that you may find with other high-quality manufacturers.
XX-Treme Barrels are built to last and made from 4150 CrMo steel, they offer exceptional barrel life and you will never have to worry about burs or a decrease in performance from heavy use. SOCOM tapering improves rigidity and thermal dissipation, allowing you to run your chosen build all day long.
*** Includes Prepped Upper Receiver, Barrel, Gas Block, and Gas Tube all unassembled ***
