The short Picatinny section is perfect for low-profile iron sights or a co-witness mount, and M-LOK allows accessory placement without adding bulk. As with any upper-end component, check barrel nut torque specs and headspace clearances during installation or have a qualified gunsmith install if you’re unsure. RISE Armament+1

Tactical / duty rigs: Multiple QD points and robust M-LOK support make this handguard a reliable choice for lights, lasers, and sling setups used in patrol or defensive carry rigs. deserttacticalsolutions.com

Care & Maintenance
Wipe down with a soft cloth after use, and clean M-LOK slots and Picatinny surfaces of carbon and grit before mounting accessories. The Cerakote finish increases corrosion resistance but avoid abrasive cleaners that can wear coatings. Periodically check torque on the barrel nut and accessory screws for safe, repeatable function.
