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

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

Griffin Armament® M-LOK compatible SR rails (Suppressor Ready) allow up to 1.5” outside diameter silencers to be mounted inside the octagonal M-LOK rail. This provides suppressor aficionados with a sleek, compact overall length for AR15-type firearms. The design objectives of this rail were to provide a suppressor-compatible rail with increased rigidity and durability compared to similar-weight, profiled 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 foregrip-type accessories, when loads are applied to the rail (such as during 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 compared with competing “slim rails” that lacked this key feature.

The new SR rails feature 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 requires no shims or special timing methods. The clamp geometry in the rear section of the rail is low-profile and ergonomically pleasing, even for extended carry at static security positions. Flathead T15 Torx screws should be tightened to 25/in pounds. M-LOK flats on each 45-degree surface allow you to mount your favorite M-LOK accessories. A contiguous Picatinny top rail ensures repeatable, accurate mounting of 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 rails.
