The adjustable SOPMOD buttstock and textured pistol grip support comfortable shooting positions, and the full-length top rail and M-LOK handguard offer ample space for optics, lights, and other accessories. Built with LMT Defense’s attention to detail and engineering expertise, this SBR reflects the company’s reputation for durable, duty-ready rifles.
