From the manufacturer

Griffin Armament SR-Rigid M-Lok Rail 12.5in Black Large. 5in outside diameter silencers to be mounted inside the octagonal M-Lok rail. This provides suppressor aficionados a sleek and compact overall length to AR15 type firearms. Design objectives of this rail were to provide a suppressor compatible rail with increased rigidity and durability over similar weight and profile current market options. A custom extrusion provides significant internal reinforcements to reduce flex when loading the carbine on the rail. These reinforcements provide rigid mounting for IR laser aimers ensuring minimal POI shift when torque is applied to fore-grip type accessories or when loads are applied to the rail such as practical shooting off barricades or when loading bipods for rapid follow up shots. Internal practical testing showed substantial reductions in POI shift with laser aimers versus competing "slim rails" that lacked this notable product feature. M-Lok flats on each 45 degree surface allow for mounting of your favorite M-Lok accessories. A contiguous picatinny top rail ensures repeatable and accurate mounting for night vision and thermal systems.
