    Best option out there

    Posted by Will on Jan 29th 2022

    I’ve tried a number of different rail covers on my rifles, always hesitant to spend the money for Railscales. Having finally done so, I should’ve the first time. Fit, finish, feel, and thin profile are Incredible. Railscales are far and away the best rail cover product on the market, I will be buying more

    Absolutely amazing

    Just got my first set of Rail Scales. The Terra Dragon. Let me tell you… these are ingenious and amazing. I’ve tried endless rail grip products. These feel tactical, yet refined. They grip amazing, even if caked with mud. Not to mention they are the best looking option out there. All my rifles are getting upgraded to Rail Scales! Don’t hesitate...

    Love it, made my smooth rail have grip texture. Use it like accelerstion cuts (stippling) on a glock for repetitive hand placement.

    Terra Core Honeycomb

    Posted by Paul L. on Oct 21st 2021

    After many orders I figured it was finally time to leave a review. I now have Railscales on every one of my guns and simply put they are perfect - the attention to detail, the fit, the finish - everything about them. I just got the new Terra Core in Honeycomb for my Radian Model 1 and they did not disappoint. This new color is awesome! Matches the Radian Brown perfectly! If you are on the fence about making an order from Railscales, just do it! You will not regret it!!

    Terracore Scales in mini dot

    Posted by Greg on Oct 12th 2021

    If you’re here, you likely want to know if these rail covers will do a good job in adding traction and heat protection . I mean, you already know how badass they look, but how do they FEEL/FUNCTION? Well my dear boy, I’ll tell you. I shoot primarily suppressed, and at a certain point with a bare rail, this usually means I need gloves to keep going. These not only offer excellent protection from a hot rail, but they also provide tactile feedback for your grip and where on the rail your hand is are resting. This is especially helpful when running drills that require removal of the support hand. All of my rifles have rail scales on them, and I wouldn’t have I any other way.
