The VKTR VK1PW Complete AR15 Upper in 5.56 with a 13.7" barrel represents the pinnacle of AR-15 engineering. This upper features VKTR's revolutionary patented low-profile piston system, offering a cleaner and more consistent shooting experience compared to traditional direct impingement systems. The thermal-fit receiver eliminates heat-related point of impact shifts, ensuring consistent accuracy. A precision-machined one-piece bolt carrier with an enhanced cam path provides shot-after-shot consistency. The 15-slot upper receiver rail creates a continuous 12 o'clock Picatinny mount, optimizing accessory space while reducing overall weight. With the pinned and welded SOLGW NOX muzzle device, this 13.7" upper achieves a 16" overall length, maintaining rifle classification while offering an ideal suppressor host platform.
