Optimizing 5.56 and .223 accuracy, with one chamber.
Trying to accurately plant 5.56 and .223 groupings with one AR-15 upper can be challenge, especially once you start working with shorter barrels. We've endeavored to fix that: Sporting a .223 Wylde chamber -- designed for optimizing both 5.56 NATO and .223 Remington loads -- housed inside a match 416R stainless barrel, this AR-15 kit's the ticket for shooting both rounds with confidence.
Also included is a custom-cut, upgraded, billet upper receiver with a side-charging handle for more ergonomic handling, paired with a mil-spec lower parts kit featuring a crisp, smooth trigger and mil-spec buffer assembly.
What’s Included
This is not a firearm. It includes an assembled upper receiver, bolt carrier group, charging handle, lower parts kit, and buffer system.
