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 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.

The new SR 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. 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 rails.

    Nice rail, good toolset and easy to install

    Published by Jeff Carpenter on 2nd Dec 2024

    I really like the barrel nut on this rail. Impossible to slip, easy to tighten up to 50ft/lbs and no timing involved. Rail is solid as a rock and shows up with everything you need. Liked it so much I went back and bough the low rail in brown. Very nice!

    SR M-LOK RAIL

    Published by Michael Hill Hill on 27th May 2024

    I typically use a slim rail for my builds and I prefer the superlative GB but, the Wilson Combat 18" barrel has a .875 gb journal and the superlative .875 has a .634 center to bottom spec which requires a larger if rail. This rail is more comfortable in the hand than most I use but, the 4 clamping bolts distort the gap on the rail. The barrel nut does make contact on all points in the rail but, I trust GA.

    SR-RIGID HANDGUARD - 15”

    Published by J P on 10th Jan 2023

    One of the best looking hand guards I’ve come across coating and finish wise. It’s nicer than others I have. Feels sturdy. Kind of wish this one came with the H900 barrel nut, but I’m sure 7075 Aluminum is plenty strong. I guess when assembled using proper torque you don’t have to worry about hand guard rotation? I’ve never had it happen, but others I’ve used have anti rotation features. Or is that just selling something you don’t actually need? Dunno. This is a smoove hand guard though.
