Overview
The SOLGW Sage Dynamics L89 is a collaboration rifle developed with trainer Aaron Cowan of Sage Dynamics. New for 2026 in a 12.5-inch length, it uses a 12.5-inch P3 chrome-lined barrel developed for the MK1, paired with the 11.75-inch 7-sided M-LOK L89 rail with integrated QD sockets. It includes SOLGW's Liberty 2-Stage (L2S) trigger tuned for a crisp 4.5-pound break, and ships suppressor-ready with a HUX flash hider compatible with HUXWRX Flow 556K and 6K suppressors (5/8x24 threading). The rifle wears a Cerakote gray finish with FDE accessories and the Sage Dynamics logo engraved on the magazine well and bolt carrier group. Available as an SBR, pistol, or 'Other' (brace/foregrip, 26-inch-plus) configuration.
