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.

Specs :
Very nice rail and easy to install. The barrel nut to wrench fit is pretty tight and the nut gets kind of scratched up but that probably doesn’t matter. I’ve used hand guards from at least 8 different brands and these are very good. Would have got 5 star if it came with a rail section.
This rail is top notch, the construction, fit, and finish are exceptional. This rail is easy to install and takes less than 10 minutes, it's lightweight, this rail is lighter than another suppressor rail I have e that is shorter in length. I just wish it came in a 14 to 14.5 in length so I can get the tucked look on my 14.5 rifle. I will be purchasing a lot more Items from Griffin.
Quality piece
Looks just the way i was hoped it would. Feels great..
I am very satisfied with this rail. Easy install, feels strong and looks good. I will likely buy another to spruce up an old rifle.
I pined and welded a suppressor to a barrel and wanted a rail that would fit over the suppressor without being too bulky and this griffin armament rail was perfect.
I have run suppressor ready handguards from 4 other manufacturers and haven't been happy with the feel or footprint any of them provided. I nearly gave up on the idea of having a handguard that could tuck away ant of the cans I run. This Griffin changed that. It fits perfectly, hugs my suppressor and feels comfortable shotting with my C-grip style. This is not the product ill be running on all of my suppressed rifles. Outfuckingstanding work Griffin!
I have a few different rails from a various manufacturers on my rifles, but this is my new favorite. It’s lightweight but feels tough, and installation was a breeze with the included barrel nut wrench. I wouldn’t hesitate to use this rail on any rifle I own and will recommend it to anyone. The 13.5 length is perfect for a 16” barrel by the way.
