MFI 5.5" Long Low Profile Scope Mount for Umarex / GSG5 HK MP5 .22 Cal. LR

Designed specifically to fit the Umarex HK MP5 .22 caliber long rifle (Pistol & Carbine)



MFI manufactures this item exclusively for HKPARTS.NET. You may contact them directly to purchase.

It is identical to the MFI standard 5.5" long scope mount that we make for the higher caliber weapons EXCEPT that the underside is machined differently to allow it to fit BOTH the GSG5 and Umarex HK MP5 pistol and carbine .22 caliber weapons.

This is the ONLY scope mount that fits the Umarex HK MP5 .22 cal weapons properly and without any modification.

You can reach HKPARTS.NET by: If you are looking for the Ultimate Low Profile Scope Mount for the 9mm, 40 S&W, 45 ACP, .223 or .308 weapons platforms you do NOT want to use this item. The CNC machining mentioned about causes the mount to be unstable and difficult to mount on anything except the GSG5 or Umarex platforms.

  1. Be sure the weapon is unloaded and the safety is on.

  2. Remove all 4 of the small bolts from the mount.

  3. Open / pull outward the bottom of the hook / lock point on all 4 points.

  4. Place the mount on top of the weapon's scope mounting points and press down. While pressure is applied press the mounting points back inward toward the receiver.

  5. Place the small bolts back into the 4 holes and down into the mounting points and tighten by hand to avoid cross threading. Alternate from bolt to bolt as you tighten to keep the mount level. Use a 5/64 allen key / hex wrench to finish tightening (do not over tighten). The mount is now installed. To remove simply reverse the aforementioned instructions.

  6. Never use Loctite or any other thread locking compound as it will take a torch to get the mount off or you will strip the bolt heads.

    The set screw is used to apply pressure down on to the top of the receiver to add stability to the extension area.

    Once attached to the weapon this mount should NOT be removed. It does NOT interfere with the iron sites or any other operation such as cleaning. On and Off removal will result in stripping the threads on the hooks.
