So you have one rifle with KeyMod and then M-LOK rolls around and you throw a handguard on the next rifle with that attachment system. The popularity of each mounting system is evident with the plethora of manufacturers adding each option to their product line up. After plunking down all of that cash on your new builds, you then have to buy the appropriate attachment accessories to make the magic happen with optics, weapon's lights, grips, etc. Strike industries has now introduced a Dual Interface rail section which offers the versatility to mount on either KeyMod or M-LOK attachment systems. It will be exciting to see manufacturers cut out the middle man and offer an interface for accessories providing a direct attach option with either system.
