Griffin Armament Low Pro Rigid M-LOK Suppressor-Ready Rail Review

About Griffin Armament Low Pro Rigid M-LOK Suppressor-Ready Rail

Griffin Armament® M-LOK compatible SR-RIGID™ rails (Suppressor Ready – Rigid) allow up to 1.5” 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. Evan Green, Business Manager at Griffin Armament states, “We understand the importance of low light targeting with IR lasers and other low light targeting systems. Reducing flex with our ID reinforcement spars reduces POI shift related to rail mounted lasers and night vision clip-ons. These rails offer more accuracy (less flex) than their competition which means more lethality under hours of darkness.” 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. The new SR-RIGID™ rails features a close tolerance, heavy-duty, 7075 aluminum, T-6, type 3 hard coat anodized finish. The barrel nut can be easily installed to 35-85 ft/lbs using the included Griffin Armorers Wrench.  The new slip fit clamp design is extremely user friendly and does not require any shims or special timing methods. 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. Flat head T15 torx screws should be tightened to 25/in pounds. The included 45 degree picatinny QD sling swivel can be installed on the top picatinny rail to the desired position of the end user.  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. If you are looking for a high quality, feature rich, American made rail system for your AR15 type firearm look no further than Griffin Armament® SR-RIGID™ rails.
