Polymer Rail Mounted Levels

Use our economical polymer rail mounted levels to ensure your rifle isn’t canted when shooting long range.  Just a few degrees of cant will cause considerable shot dispersion at longer ranges!  If the scope is canted by only 2½ degrees, the bullet will impact .05 mils for every 100 meters in the direction of the cant. This means with only a 2½ degree cant and shot of of 1000 meters would be an impact of .5 mils. A small change can make a big difference and our polymer rail mounted levels are an economic way to solve this issue.

    Great product. I bought mine in carbon fiber. It fits great under my scope and is clearly visible when I’m on the gun.

    I bought 3 for different rifles. Tikka and Cooper worked perfect. The VX6 on the C.A. Ridgeline would interfere with ejection or bolt handle depending on where I mounted it. So I just purchased a scoped mounted level from MKM. I’m sure it will be awesome like everything else I have ordered from them. One note, don’t over tighten the rail mount levels. I did on first one and cracked it. My fault. I always over tighten things. Great product . I highly recommend !

    Cheesy looking. I guess I should’ve spent the extra $$ and got the aluminum. No way will I put this on my AR. It would break off on day 1.

      Hi Billy,

      Quite certain it won’t break off, we’ve sold thousands of these! That being said, our aluminum ones are quite stout, and reasonably priced. Our product photos are accurate of these. Not sure what you expected to receive, beyond what is pictured?

    I picked up an FDE rail mounted level over a year ago. Super easy to install and adds negligible amount of weight to the overall set up of my rifle. It’s a simple addition to help improve accuracy when shooting long distances by reducing the instance of canting the rifle. Glad I added it to my set up!

    Something is messed up. It does not sit level with the rail defeating the purpose. I didn’t even tighten it down and it doesn’t sit flush.

      The polymer levels are built with a slight cant that is meant to be level under slight torque as the material is not as rigid as our billet levels.

      Tighten it down and it should become level! Email [email protected] if you have any questions.
