The design is nothing major or earth shattering, it’s just something I thought was needed for the industry. My goal is for the industry to make this system a standard; working in parallel with the Picatinny rail; not replacing it. I’m not taking credit for coming up with this “keyhole” design, because I found out a year and a half ago that Accuracy International was working on a similar program. Also, it’s hard to take credit for a design that’s been around for 100+ years, i.e. warehouse shelving, scaffolding, etc.. Plus, with close examination of the A.I. key slot design, there are a number of improvements that the KeyMod covered and improved upon.
The main difference is in the mounting and re-zeroing capabilities of the component. In addition, A.I.’s design was never taken into consideration for counter-recoil but recoil only.
With this official introduction, I’m releasing the prints (shown below) to the firearm industry, so fellow companies can develop their own rail systems/platforms utilizing the KeyMod configuration. I added a sample component print (4-inch rail section) showing the mating interface to the outside of the platform surface. I also included a picture of the accessory nut that interfaces/ indexes to the chamfered surface on the backside of the platform. Please note the nut has a counter bore, so the mating screw can be distorted at the tip. The thread distortion will stop the screw from backing out, making the accessory a self contained, self centering, “drop and slide” mounting component. As you can imagine, there are a number of companies that are already developing and/or manufacturing components that mount directly to the slots. For example, Noveske and I are making our own rail panels, to work with “our” platform requirements. Other items being developed are VFGs, handstops, bipods, light, sight and sling mounts. The possibilities are endless.
In all, I see this design as being a viable solution to limit the use of the aging “cheese grater” Picatinny Rail and/or multiple mounting points, which require threads, Helicoils and thread inserts. It is time to move on and I think the industry is ready for it. Vltor.com.
