    Griffin Armament introduces their new line of M-LOK rails, the SR-RIGID series.

    Griffin Armament is best known for their silencers. They’ve been putting out quality cans since their founding in 2006, and many of their models have enjoyed significant success. From their versatile Bushwacker 46, the user-configurable Optimus, their 30SD-K model, the modular Resistance 22 rimfire can, to their new GP-N A2-mountable can, and many more, Griffin usually has at least one suppressor, if not multiple options, capable of filling virtually any role for which you might need a can.

    In addition to their silencer line-up, they also make a variety of other firearms-related parts and accessories, like barrels, QD pistons, and backup iron sights, among others. Now with the following April 21st announcement, they’re releasing a new series of M-LOK rails called the SR-RIGID line, with the “SR” standing for Suppressor Ready. Read the announcement below.

    One intended benefit of the SR-RIGID rails is to combat shifting, when bracing or other pressure might threaten to flex your rail.

    NEW SR-RIGID™ M-LOK Rails (Suppressor Ready – RIGID)

    Griffin Armament® M-LOK compatible SR-RIGIDTM 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.

    “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.”
    -Evan Green, Business Manager at Griffin Armament

    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-RIGIDTM 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-RIGIDTM rails.

    Griffin's new rails are intended to fit suppressors of up to 1.5" diameter inside of them, for those who want a bit of extension on their rail space.

Do Griffin’s new SR-RIGID rails seem like they might benefit you? Have you ever run into any issues with other rails flexing as they describe? Have you tried using any other rails that were meant to allow a suppressor to recess under them, and how did that go? Will you be picking up one of these new SR-RIGID models, or giving them a pass? Let us know your thoughts in the comments below! See you at the range.
