The clamp geometry in the rear section of the rail is low profile and ergonomically pleasing even for long durations of extended carry at static security positions. The new slip fit clamp design is extremely user friendly and does not require any shims or special timing methods. The barrel nut can be easily installed to 35-85 ft/lbs using the included Griffin Armorers wrench. The new SR-Rigid rails feature a close tolerance, heavy-duty, 7075 aluminum, T6, type 3 hard coat anodized finish. Internal practical testing showed substantial reductions in POI shift with laser aimers versus competing slim rails that lacked this notable product feature. 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.

These rails offer more accuracy (less flex) than their competition which means more lethality under hours of darkness. Reducing flex with our ID reinforcement spars reduces POI shift related to rail mounted lasers and night vision clip-ons. A custom extrusion provides significant internal reinforcements to reduce flex when loading the carbine on the rail.Įvan Green, Business Manager at Griffin Armament states: We understand the importance of low light targeting with IR lasers and other low light targeting systems. This provides suppressor aficionados a sleek, and compact overall length to AR15 type firearms.ĭesign objectives of this rail were to provide a suppressor compatible rail, with increased rigidity and durability over similar weight and profile current market options. Griffin Armament MLOK compatible SR-Rigid Rails (Suppressor Ready - Rigid) allow up to 1.5 inch outside diameter silencers to be mounted inside the octagonal MLOK rail.
