The ultimate long range AR-15 upper is finally here!
The 224 Valkyrie round was developed to bring unheard of accuracy and long range ballistic performance to the AR-15 platform. 
Barrel: The PSA 224 Valkyrie upper receiver was created with a 416R Stainless Steel barrel with a 1:7 twist rate for optimal accuracy over long distances.  Cycling reliability is achieved with a rifle length gas system, which is completed with a PSA Low-profile adjustable Gas Block.  The barrel is finished off with an A2 flash hider and a PSA 15" Lightweight M-Lok Rail.  
Upper Receiver: The forged 7075-T6 A3 AR upper is machined to MIL-SPECS and hard coat anodized. These uppers are made for us right here in the USA by a mil-spec manufacturer.
**These uppers may have cosmetic blemishes that do not affect function. This may include, but is not limited to, forging marks under the finish, scratches, dings, slight variation in the finish color coat.

I almost went for this but saw Primary Arms had the Radical Firearms in a similar / slightly better configuration, non blem and lower cost. Just saying if anyone is thinking about this you may want to compare with Primary Arms. The Radical also comes with the muzzle brake upgrade vs the A2 birdcage flash hider.

It's an option but it's not less expensive at $450. PSA has non blemished versions for $399 shipped.

Just got an email from Primary. Radical Firearms 224 Valkyrie uppers are on sale for $379-399. Reviews on these uppers are not too great though on accuracy and quality control.
