- Alloy construction
- For MP5K / CM.041L AEGs
- Modification may be required
If your CM.041L receiver is looking a bit tired, this replacement will have it looking fresh again! The CYMA Metal Upper Receiver for CM.041L MP5K AEGs is a factory-original replacement part for the CYMA CM.041L MP5K AEG. It may fit other MP5K AEGs based on the original TM design, but will likely require modification, so have your tools handy.
Like the original CM.041L receiver, this alloy receiver features H&K claw mount lugs built in, allowing you to add a 20mm Picatinny rail mount and use optical sights. The set includes the upper receiver alone, so make sure you've got your trim parts from your original MP5K to complete the build.
