http://www.talonarms.com/talonarms/index.php?main_page=product_info&cPath=320&products_id=795 This is Talon Arms write-up of the upper with specs - This falls into the "Your stupid if you don't buy this" category. I could not imagine how well this could have turned out before the first one was built. This is the ideal set up for medium range sniper weapon system in 6.8 SPC.
A Vltor VIS with shell deflector and forward assist (mid-length) was used as the host for the WOA 18" barrel. The advantage to the VIS is the single piece construction of the upper receiver and the free float rail system. This is the most rigid platform available for use with our high performance, professional match grade barrels. That rigidity and single piece construction means that the VIS is the perfect receiver to use when accuracy is the primary goal. The Picatinny rail system has plenty of space available for any tactical accessories you may need; such as a bipod, lights, lasers, and IR illuminators. The continuous top rail is ideal for use with high-powered scopes where longer eye relief is required. A riser rail is not required because the scope rings can be mounted as far forward as you require with no risk of twisting or bending your scope body. Leupold Mark 4 super high rings are recommended.
A stainless steel White Oak Accuracy barrel was selected because of the outstanding reputation for accuracy and quality. We offer both a lighter weight 16" barrel and the 18" heavy barrel and opted to build with the 18" version to maximize velocity and minimize barrel flex. The barrel is fluted to reduce weight and increase barrel surface area to aid in cooling. A Duracoat ACU Grey finish was applied to the barrel to reduce the glare of the stainless finish and better blend in to the variable surroundings that might be encountered in an urban or suburban area. A matched bolt and JP stainless steel tactical bolt carrier are also included. The flash hider supplied is the Smith Vortex.
