These accessories are designed to direct mount to handguards using the universal KeyMod system.
KeyMod™ The New Standard in Modularity
Round recoil feature works in all axes, tapered fit of
KeyMod™ nut ensures fore/aft tension bias.
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
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.
