[KM Planning] DMR Frame Set for Marui Electric Scorpion

All parts are machined from aluminum, and the thick frame structure provides increased rigidity and allows for bolt-on installation. The stock is made of high-quality Japanese wood.



The undergrip frame is equipped with a hole for battery replacement, so you can replace the battery by simply removing the stopper screw while the frame is attached.
A special tool for battery replacement is included, making it easy to open the cap.

You can attach a sling swivel to the bolt on the undergrip frame on either the left or right side. *Swivels are included.

Like the MAC10 frame lock mount, the sight frame has sight holes on both the front and rear mounts so that the iron sights can be viewed through.
Even if you are equipped with a scope or red dot sight, you can aim with the iron sights by looking just below.



The mounting rails, including the under-mount, are all Tokyo Marui's [Side Support Rail Set for G36C] .

"Caution when installing the mounting rail"

When installing the upper mounting rail, be sure to insert the included wrench vertically and tighten it lightly.
The screw thickness of the upper mounting part is thin, so if you tighten it horizontally with a high torque, the threads will be stripped.

The front attachment is made by removing the original hider, covering it with the attachment, and securing it with a silencer.
The screws on the gun are reverse threaded, so the parts required will vary depending on the type of thread on the silencer you are installing.
(The KM Kikaku silencer series is reversible, so it can be installed either way.)

KM Stout Silencer Series

The DMR set includes the KM Planning Custom Silencer Adapter (Forward/Reverse) [SAJ02].

A custom silencer adapter is required to install the front attachment.
To install a reverse thread type silencer, please prepare one separately.

"Caution when installing the mounting rail"

When installing the undermount rail, be sure to insert the included wrench vertically and tighten it lightly.
The undermount screw is thin, so if you tighten it horizontally with a high torque, the threads will be stripped.

To install, first remove the original hider, then insert the custom silencer adapter, then place the front attachment over it and tighten the silencer to secure it in place.


If you are installing a reverse-threaded silencer, use the KM Planning Custom Silencer Adapter Reverse to Reverse [SAJ03].

The custom-sized long barrel compatible with the Scorpion is the TN barrel for the Marui electric HK MP7A1. Use it in conjunction with a barrel vibration prevention spacer and centering spacer.

KM Planning 35 Stout Silencer Anti-vibration Insert

M14 positive thread, barrel outer diameter 8.5mm, barrel hold, metal type

M14 reverse thread, barrel outer diameter 8.5mm, barrel hold, metal type

〇Scorpion drum magazines can also be attached.

The front attachment is based on the KM Planning Stout silencer. Please use a silencer with an outer diameter of 35mm.

*When installing the front attachment, the under-rail of the front attachment cannot be used with the original under-rail. Please remove the original rail.



If you are using the genuine pin to secure it, spray lubricant on the pin, push it in halfway with a plastic hammer, and then secure it with a screwdriver.

Please note that the threads on the genuine pins are easily stripped.

Alternatively, it can be fixed with the included pin.



There is only one sling swivel on the underframe. We recommend using a SWAT sling compatible with all HK electric guns, as shown in the image.
