Detailed Product Description

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. This anti-rotation variant features a tab at the rear of the rail that locks into Griffin MK2 Upper Receivers to prevent unwanted rotation of the handguard under stress.

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.

SR rails features a close tolerance, heavy-duty, 6061 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 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.

A shim is positioned between the clamp boss that locks into the barrel nut preventing pull-off of the rail. 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.

Anodized Color Note: While we strive for consistency in the color of these components, there are some inherent differences in final color outcome that are out of our control due to the anodizing process which depend on many process parameters such as material alloy (6061 (Rails, optic mounts) 7075 (upper/lower receivers, charging handles, receiver extensions), material heat/lot, material process (extrusion, forging, impact extrusion, etc), material condition raw or machined/cut, anodizing water process temperature, acid etch time, rinse speed and time, dye concentration, anodize time, current intensity, blasting media condition, blasting angle variation, etc. This is well known at this point among consumers in the industry with “fifty shades of FDE” colloquialisms describing the variations in color possible in anodizing of colors lighter than black. The product you receive may be a somewhat different color than what is pictured due to these aforementioned variables in the electro-chemical process. Additionally, small cosmetic imperfections usually hidden by the black anodizing process are more easily seen due to the lighter pigment of the different dyes. Because these issues are inherent to the process, slight cosmetic imperfections may not be pulled from inventory and marked as a blem. This is a risk of purchasing a non-black product and should be expected to a degree. We will not sacrifice the functional performance of our products, and any issue that affects performance will not be sold. Anodizing fortunately doesn’t have the level of increased cost premium associated with the intensive labor involved in painting rifles (something we simply don’t have the available labor pool locally to support, nor do we believe the customers want to pay the premium for), so color being possible in that atmosphere at no additional cost is a major process benefit of anodizing. If the above mentioned conditions are unacceptable to you, we encourage you to purchase black anodized parts.
