This Airsoft3D adapter converts MP5 claw mount to Picatinny mount or Weaver mount. Basically, this adapter allows you to mount MP5 claw mount accessories--scopes, sights, etc.--and MP5 claw mount risers to Picatinny rails and Weaver rails. NATO accessory rail is almost identical to Picatinny rail, therefore, this adapter will work with NATO accessory rail as well.
In general, you will need two of these adapters to mount a MP5 accessory to your Picatinny rail. Therefore, you will likely need to order two of these adapters. Note that your Picatinny rails must match the official Picatinny specification for a pair of this adapter to work. If you have a Weaver rail, or other non-standard Picatinny rail, these adapters may require customization and expert installation. The Picatinny specification is located on Wikipedia here:
You will need a #6-32x1-1/4" screw and a #6-32 nut to fasten each of these MP5 claw mount adapter to the Picatinny rail. The screw and nut are not include, but can be easily sourced from your local hardware store (e.g. Home Depot, Lowes, etc.).
Airsoft equipment used for illustration of this Mount MP5 Scope to Picatinny Rail adapter are not included.
WARNING: Although you can use these mount adapters on your real firearm, we have never tested them on a real firearms before. We do not know if the firearm heat/recoil will or will not damage these adapters or the accessory you will fasten to it. Use it with real firearms at your own risk.
