​THE PMM MLOK Rail Extension (MRE) Works extremely well with a variety of MLOK style mounting System accessories as well as illumination devices and IR/Laser combo’s. Below are some specific images highlighting the types of configuration a shooter can use, as well as the mounts for each set up.

The Arisaka Defense Offset Picatinny Mount, Is in PMM’s experience the most versatile 45* offset mount available. The Picatinny Portion on the mount can be configured to mount in a variety of offset heights which allows the shooter to move the centerline of the Required accessory close to the bore of the rifle. and is reversible for both left and right handed shooters. Additionally if you are running a Surefire or Arisaka Light you can mount the flashlight directly to the 45* base plate.
