Federal Concepts Upper/Lower Receiver Cover for AR/M4

Our receiver covers:

• Protect the internal components of your replica from unwanted bumps, dust and/or debris.
• Unwanted removal of the Bolt Carrier Group or Charging handle from the upper receiver.
• Protect any bag from any oils or lubes, contained inside the replica.
• Marking Matrix for easy identification. Grab a paint pen and mark up the tinny squares with your desired information.

The upper receiver cover is a snap on design, ensuring no pins are required (usually ending up lost or broken, over time). Will require some wearing in when first acquiring one. Our receiver covers are perfect for storing multiple builds or when transporting in a bag where the replica needs to be broken down to fit.

Compatibility: Compatible with factory receivers for TM MWS, GHK M4, VFC M4, Vipertech M4, Systema M4, GBLS DAS GDR15. Also compatible with Milspec AR-15 receivers.
(WE M4 receivers are compatible with our VFC M4 receiver covers. For the upper receiver cover, they require minor sanding of the two tabs located on the rear pin hole.)
(Aftermarket receivers for any of these models have not been tested and not guaranteed to be compatible)

WARNING: These covers are 3D printed using FDM technology. Although we check each one during inventory, there may be cases where they might not fit due to slight tolerancing issues.

If during use, you notice any issue with your product, don't hesitate to contact us!
Some filing may be required to fit your specific receiver.
