Product Overview

Now shipping with our new custom Torx T20 fasteners!

Solo's™ - Single MLOK slot RailScales® for short rails commonly found on subguns, pistols, or filling in one slot to finish out your build. Offered in all 4 of our patented textures and utilizing only one screw and MLOK nut in the middle of the scale to maximize the texture field. CNC machined out of high-quality US-made Black FR4 or our brown terrain-colored TerraCore™ (commonly known as G10), our scales provide an unmatched barrier against heat transfer. These will also fit in and fill the slot of our XOS-Hwrap-around scale. Our MLOK rail panels are the thinnest G10 rail grip scales on the market. Our name says it all, as we innovated the machined scale concept and remain at its technology forefront. Sold Individually

G10 RailScales in MLOK - 1.5 Slot - New for 2023. Introducing our 1.5 MLOK Slot Solo's™. Like our 1 Slot Solo's™, these utilize only one hardware mounting location to allow for fine-tuning modular mounted texture and heat protection. Designed to be used with shorter MLOK rails commonly found on sub-guns, and pistols, or for filling those empty MLOK slot gaps to finish out your build.  

TerraCore™ complements our line of Terra Bronze™ anodized and FDE polymer components as well as third-party branded tan anodized or Cerakoted rail forends. Unlike coating or painting options, our TerraCore™ scales are colored throughout and remain so after CNC machining operations. Offered in the same patented textures and resilient heat protection options you've come to expect. We are excited to introduce TerraCore™ Solo's™ to our lineup.

    For what these do I think they are the best. They reduce heat on those smaller hand guards while giving you the best grip. My favorite are the mini dot.

    Got the dragon scales for the lonely Mlok slots on my MDRX Mantis 16" Handguard. Turns out that spot is where your fingers naturally land and these scales are grippy and solid. Don't know about other patterns but the dragon can be reversed for more or less grip when shouldering and pulling the rifle toward you.

    Slot solos

    The honeycomb slot solos that I purchased, look right on my rifle, and did a good job of filling in the gaps where needed, for heat protection. They seem to be indestructible.

    Single slot railscale

    Posted by Justin Dawn on May 15th 2022

    I irdered a couple single slot railscails in the diamong pattern. They shipped very quickly. There was an issue with usps so i called customer service. They responded showed concern and imediately put in a claim. I finally got the scales. Fit and finish was fantastic. The pattern looked great. The points were a little more aggressive than i liked, but that is personal preferance and no way justifies a lower rating. I just hit them with a 1000 grit sandpaper and are perfect for me now. I will not hesitate to order more. Great accessory.

    Solo Scales

    Posted by Hunter on Mar 27th 2022

    Perfect fit for the MPX-K (because the screws are in the middle) I bought 4 total. The 2 slot scales won’t fit on the right side because of the gas block (screws are closer to the edges causing it to hit) very high quality and won’t hesitate to buy more when I get another new firearm.
