New Gear: Kinetic Concealment’s CompRail System


Kinetic Concealment launched a new product called the CompRail System. The CompRail System is an optic mounting platform for pistols that uses the handgun accessory rail. The idea is to allow for the placement of a red dot style sight without the need for machining the slide.

Developed for the competition market, the CompRail System could also work for other shooters who are looking for an inexpensive way to add an optic. The platform seems very affordable at $25.95. A slide machined to take a RMR or similar optic will cost you much more.

Currently, the CompRail System is designed to work with:

  • 1911 style pistols with a rail
  • SIG SAUER P250
  • Smith & Wesson M&P (full size, all calibers)
  • Smith & Wesson M&P (compact, all calibers)
  • Beretta 92
  • Beretta 96

It is possible that the system will work with other guns such as the SIG P320. However, the company cautions that the unit attaches to the pistol with two hex head bolts, so sub compact pistols with a single rail slot will not work with the CompRail System.


Once attached to the gun, the unit gives you a 2.25″ length of Picatinny rail to mount your optic of choice. Kinetic Concealment states the system has been tested with calibers up to .45 ACP.

Kinetic Concealment got its start making hybrid holsters. Since then, the company has expanded its catalog to include other accessories such as lasers, lights, sights and knives.

    Hmm this could also be helpful for a hunting pistol

    • iksnilol

      Put a decent 4-14 scope on it and you’re set 🙂

    • Giolli Joker

      Tested up to .45ACP doesn’t sound promising if you want to use hunting calibers like 10Auto or .460 Rowland, though.

      • JustAHologram

        That why I said could not will be

  • Havok

    I’m not that big on the competition scene….but what holster options would work with this thing?

    • Xtorin O’hern

      most competition style holsters would

  • TheNotoriousIUD

    That looks promising.

  • Sasquatch

    No glock compatibility? Finaly a company realizes that there are other handguns.

    • Anonymoose

      It would probably work with those old G21s with the Pic rails.

      • TheNotoriousIUD

        Thats what im counting on.

    • Harry’s Holsters

      ALG ate up that market so KDG is going for this one.

      • Cuvie

        Kinetic Concealment has no relation to Kinetic Development Group

        • Harry’s Holsters

          Thanks for pointing that out. I need to read slower! haha

          • wetcorps

            To be fair, you could make a double entry table with words like Kinetic, Tactical, Operator, Dynamic and a few others and recreate most of the company names in the industry 🙂

          • Harry’s Holsters

            Got that right! I don’t understand why all these guys start brands that “blend in” so easily.

      • ??

        The 6 second mount is very well made and works very well. Now if only the rear pin mount could be eliminated or radiused or concaved. Carver, SJC, and others all have a similar concept and same problems. A big ass mounting point right next to your trigger finger. If you run a lot of rounds through any you will understand. ALG bought a hella expensive machine to make these, but failed to understand the true ergonomics of the end product. Dremel tool to the rescue.

        • Harry’s Holsters

          Never handled one I just know people seem to love or hate them. This is the first time I’ve seen this brought up and it makes complete sense. As someone with thick Glock knuckle I can relate.

          From a machining/strength standpoint is it viable to to reduce the profile in that area?

          • ??

            I would think so.

          • Sunshine_Shooter

            Since that mount is made of aluminum, going very thin right there could lead to higher failure rates at that point. If it was steel it would probably be fine, but the weight wouldn’t be worth it.

        • Bill

          No live eject, ejection or chamber-checking issues with all that junk over the ejection port?

          • BattleshipGrey

            With the Glock you should be able to see if the chamber is loaded by looking just forward of the extractor on the starboard side (either with a slide press or just looking at the slight gap to see the brass cartridge). That particular extractor also has a loaded chamber.

          • Sunshine_Shooter

            Think about when the slide moves under recoil. The ejection port may be crowded while in battery, but is free and clear when actually ejecting.

          • Bill

            Good point, I don’t factor in the amount of rearward movement. Thanks.

  • Anonymoose

    Should have tested it with .460 Rowland and .50GI, and also allowed you to still mount a light/laser underneath. Even so, it’s about time someone came up with something like this that doesn’t require you to drill holes in your frame or use a Glock.

  • DanGoodShot

    These are nothing new. Pistol rail mounted optic mounts have been around for quite a while. Heck, Amazon has had them for sale for atleast past 3 years. I believe the price is about the same too. I know the maco group has had one out for a while.

  • Greg Anderson

    I’m not a huge fan of kinetic concealment after taking a chance on their green laser/light combo. It’s very meh. A critic might say that the reliability of the laser/light combo has little to do with the performance of a red dot mount, but given that I found the material used in the mounting hardware to be quite soft, it’s a reasonable extension.

  • Oldtrader3

    Nope, not for me! Fugly and cumbersome!

  • noob

    Hmm. No additional 6 o’clock rail space under the rail for the light?

    If they had, you could mount a light and then use one of those holsters that grabs onto the light, so you don’t need a special custom job holster to accomodate the weird optic position.

    I wonder if there are patent protection issues preventing this?

  • Treyh007

    No Glock or XDM…… this would be good for a suppressor host as well! For $25 I might try one out but I’d like to know if they also fit the 2 pistols I mentioned?

    • Gary Kirk

      May be a front sight interference issue?? Might fit fine with the sights removed?

    • Sunshine_Shooter

      It attaches to a standard rail and has a lot of clearance between the mount and the M&P slide. I’ll be really surprised if it doesn’t fit 99% of the pistols on the market.

  • M1911

    Much too high above the bore axis for my taste. I’ll stick with my Glock MOS.

  • Mike

    Would be a cheap way to try out a mini red dot on a pistol without the expense of buying an optic ready pistol. I am thinking about buying a Glock 19 MOS

  • Gary Kirk

    Looks crooked..

  • Frank Grimes

    Concealment, huh?

  • Sunshine_Shooter

    The fab defense costs more than twice what the one above costs.

    • Redfoot

      Well…crap. Did not see the MSRP above. Makes it even more atractive then.

      • Sunshine_Shooter

        I know! If the mount can hold a decent zero when attached to a polymer rail, I’ll be very interested.

  • Creepermoss

    “New Product”, no. New product from this company, sure. I asked my uncle, and he still has the one he used for bullseye shooting back in the early 80s.
