About the NcSTAR VISM Keymod Picatinny Rail Segment - Medium

This aluminum rail segment allows you to add a picatinny rail compatible tactical accessory to your Keymod forend.

So you just got your newest gun which has Keymod and you want to start adding some accessories to it but now you're short on money. Did you have another gun you upgraded from with some cool attachments you could move over? If so, these keymod picatinny rail segments are just for you! It seems kind of backwards to want to go back to picatinny style rails after this but some legacy attachments that you got that were pretty cool and still very much functional are still totally viable options for you to use. Got a neat grip? A light? A bipod? A laser maybe? Or even if you don't have one, the item you ARE looking to add has an integral picatinny mount. If you own any of these attachments, all of these costed you money at some point and you can breath a second life into them.

If the terms are completely new to you let us go back a few steps to clarify what some of them mean. The MIL-STD-1913 rail or Picatinny rail as it is more commonly known is a mounting platform for accessories that allows your rifle to be modular. These look like little ladders and are found on the forend of all tactical style guns these days. The picatinny rail has been long established and is the most common mounting platform for accessories. In the recent years, some manufacturers have come up with their own idea to streamline the modular accessory market. One idea was Keymod, which replaces the picatinny rails with key shaped holes machined into the forend. The idea is the gun now is very sleek and has a slimmer profile, and you would add accessories just where you need them and not end up with an excess of unused rail space which nets a heavier overall weight on your forend. The design and specifications for Keymod are open source so any other manufacturer can make guns and accessories Keymod ready. 

How keymod works is you have an attachment that will have two round lugs with bolts attached to them. The lugs are the same diameter as the large part of the keyhole. You will mate the accessory to the mounting surface then slide the accessory forward so the lugs are now supported by the narrow part of the keyhole. You will then tighten the two bolts until the lugs grab onto the rail system. On the inside of the keyhole is some additional machining done of the rail so that the lugs are guided and have a place to secure to. This ensures the best and most secure fit so that your accessories do not come off when put under recoil.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
