H&K MP5, HK94, and SP5K Rear Sight Drum and Base
This is an HK German part that's a great upgrade for the SP5, SP5K, and SP89 or MP5K models. We highly suggest adding the following items to complete the rear sight set that's not included.
- Sight Bearing
- Sight Bearing Spring
- Windage Screw
- Oval Washer
- Locking Washer
- Clamping Screw
Please note: This is built using a new HK German MP5 drum with a like-new/new rear sight base. Each unit will come fully assembled, less the mounting hardware. This picture is an old stock photo and may not be the exact thing.
