Overview

Built for shooters who demand precision above all else, the WP360 .223 Wylde Upper is designed to deliver tighter groups and greater consistency than standard 5.56 NATO configurations. The .223 Wylde chamber offers the strength and reliability of 5.56 while maintaining the match-grade accuracy of .223 Remington, producing superior precision with either ammunition type. 

Featuring a forged 7075‑T6 aluminum upper machined to true Mil‑Spec standards and a 16" QPQ-treated barrel, this setup guarantees long-term durability, smooth cycling, and exceptional shot-to-shot consistency. The free-float 15" handguard enhances accuracy by eliminating barrel contact, while the included premium bolt carrier group, standard charging handle, and metal flip-up iron sights make this a complete, ready-to-run package. 

Fully assembled, range tested, and sighted in, it ships zeroed and ready for performance straight out of the box—all proudly made in the USA.
