WWSD2020 - Project Launch & Mk3 Lower Announcement
The WWSD2020 project launches its Mk3 polymer lower, a refined evolution of previous monolithic designs. Developed in partnership with KE Arms and exclusively distributed by Brownells, the Mk3 features a flared magwell optimized for PMAGs and D60s, improved grip ergonomics, and M-LOK slots. This project aims to create a modern, lightweight AR-15 inspired by Eugene Stoner's original design principles.
