The MAKO group lets you add two Picatinny rails to your regular AR handguard. Made with an offset this piece bolts to the holes in your handguard to provide 2 rails. No need to get a complete new handguard if you just want to add a light or laser to your weapon and this could even mount an offset Red Dot Optic as a backup to your main sight.
