CLICK HERE! To look at the new LOW-PRO-RIGID™ rails!







Griffin Armament® M-LOK compatible New LOW-PRO-RIGID™ rails have been re-engineered to offer a user friendly installation while continuing to provide a slim, low profile, ultralight, yet rigid handguard that past users have loved.

Design objectives of this rail were to provide a slim, ultralight rail, with increased rigidity and durability over similar weight and profile current market options. A custom extrusion provides significant internal reinforcement to reduce flex when gripping the carbine firmly in the shoulder pocket.

Evan Green, Business Manager, of Griffin Armament states, “We understanding the importance of low light targeting with IR lasers.  Reducing flex with our ID reinforcement spars reduces POI shift related to rail mounted lasers. These rails offer more accuracy (less flex) than their competition which means more lethality under hours of darkness.”

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 70% less POI shift with laser aimers versus competing "slim rails" that lacked this notable product feature.

The new LOW-PRO-RIGID™ rail features a close tolerance, heavy-duty, 17-4 stainless steel H900 heat treated barrel nut, which can be easily installed to the specified 55 ft/lbs with 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 slots at the 3, 6, and 9 o'clock positions allow for mounting of your favorite M-LOK accessories.

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® LOW-PRO-RIGID™ rails.

I'll check with the inventory manager and marketing management.

A marketing person was able to remote in from home and fix it.  It was website related- the inventory build was created.

We're going to be updating the pages with appropriate weight information today. Weights haven't changed very much, but thank you for the question.

The media department weighed the rails and these are the numbers:

OAL    OUNCE WEIGHT WITH BARREL NUT

8.6"      7.8
10.5"    9.0
13.5"    10.8
15"       11.9

The rails are exceptionally rigid.  The pattern of the offset slots is itself a 60% improvement in rigidity before you get to the internal ribs, and the 17-4 nut and pinch design really promotes rigidity.

The wrench supports a 1/2" drive needle torque wrench, the GI barrel nut, so it's like getting a combination GI wrench with the purchase.   The tool has the 3/4" open wrench for the muzzle device, the 5/8" open wrench for the A1/A2 buttstock or XM177 moderator, the castle nut for this barrel nut or the CAR stock and many suppressor components in our line, the bottle opener, a geometry for removing a taper mount from a suppressor if it wasn't torqued properly on installation, a bladed screwdriver (sight tool), and a 1/4" bit driver hex for whatever other tools you might need to use in a pinch.

The price will probably be a little lower than the 8.6" model.  (EDITED) The 7.5's are being programmed and should be in production soon.  The line started with 4 SKU's and the other 3 are coming.

Hey guys, just added the installation tutorial for the new LOW-PRO-RIGID™ rails to the original post. The tutorial demonstrates the simplified installation process. Enjoy!

Thankyou we try really hard.  We have some neat stuff in the pipeline.  The releases will be coming.

This silencer was just released for example.  Media is working on releases as fast as they can produce the content.
