Very rigid, just like they claim
Fit and finish is perfect
Griffin Armament® Low-Pro rails are a slim, low profile, ultralight, yet rigid M-LOK rail. Design objectives of this rail were to provide a slim, ultralight rail, with increased rigidity 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. Understanding the importance of low light targeting, 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 (shooting off barricades, loaded bipods etc). Internal testing showed 70% less POI shift with laser aimers versus competing "slim rails". Carefully positioned slots in the rail allow for rapid cooling when running the carbine fast while maintaining rigidity.
The Low-Pro rail features a close tolerance, heavy-duty, 17-4 stainless steel H900 heat treated barrel nut, which can be installed with the included Griffin GI Armorers Wrench. The rail is very user friendly to install. The slip fitted clamp design doesn't requiring any shims or special timing methods. The clamp boss in the rear section of the rail is low profile and ergonomically pleasing for relaxed posture carry at static positions. Flat head T15 torx screws should be tightened to 25/in pounds. The barrel nut should be tightened to ~55ft/lbs.
M-LOK slots at the 3, 6, and 9 o'clock positions allow for mounting of your favorite M-LOK accessories.

Terra Brown 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 Terra Brown dye. 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.
