Moriarti's 20 inch AR-10 308 diamond and spiral bull upper assemblies are the biggest sellers and sought after DPMS profile upper assemblies.
For the past three years, Moriarti's biggest seller has been diamond and spiral fluted upper assemblies. Really scarce to get because of it's precision fluting, these barrels just give you so much precision and fun at the range.
Why these 308 20 inch DPMS profile barrels are scarce? Well, there are not many suppliers available for finished blanks. That's one. The second issue is the fluting - not many vendors know how to flute even if they promote it. One not only needs the machines but also know what to do with them - and diamond cut is the most difficult to do. Expensive run. Very precision based. If not done right, the barrel will come out looking, well, not right. 308 Barrel extensions - your next step. If something is off in that, then the barrel that you pay your top dollar for is not going to work.
AR-10 308 DPMS profile barrels - the heart of your AR10 rifle. It has earned a loyal following among firearms enthusiasts worldwide, and is sure to continue dominating the scene for years to come.
