KeyMod™ The New Standard in Modularity


  • Round recoil feature works in all axes, tapered fit of KeyMod™ nut ensures fore/aft tension bias.

  • Tapered/chamfered surfaces act to place load on part to ensure that there is no slip under recoil and part will return to the same position (V-Block design) each time it is installed. Without these tampered/chamfered surfaces accessories will be much more prone to movement under recoil and counter recoil.

  • Chamfered and a controlled depth feature allows for mounting hardware to sit much lower profile inside the handguard, this allows running suppressors inside of handguards (where applicable) or accessories under the gas block on slim-fitting handguards.

  • The through-hole is sized to clear a sling swivel, this means that sling attachment points are as low-profile as possible.

  • Readily available gages and inspection criteria, and use of standard angle cutters make it an affordable option for machining/manufacturing.

  • Widespread adoption leading to a robust and growing accessory list from most every major tactical accessories manufacturer.

  • Design is public domain. This was done on purpose so as to create a standard anyone is free to work with, just like the Picatinny (MIL-STD 1913) system. The free use of the standardized Picatinny system is what has allowed the small arms accessory market to expand to produce much effective tools. Any means and methods of attachment not yet patented are free for anyone to develop without potential royalties.
