    Parts List/what you need to provide or purchase above:

    • UMP Lower housing w/ mag release and buffer plate ( or complete UMP lower. *US made lowers not recommended )
    • UMP rear hinge stub/cut-off
    • UMP stock
    • Stock axle pin
    • UMP locking/takedown pin

    Color/Finish: Some parts may or may not match other parts of the same or other manufacturers. ( Especially tan/FDE/RAL8000 ) It’s a well known fact that anodizing is very picky/hard to match. Most manufacturers do not guarantee color or color match, even among their own parts or batches. It’s too inconsistent to make that guarantee. The polymers are also this way. The same holds true with our products, both originals and reproductions.
