Solid aluminum, very sturdy. Coloring closely matches the hk finish. Pricey, but a required part for the USC/UMP conversion. Fast shipping as usual!!

This block for your UMP conversion is engineered with tight tolerences and in my case required zero fitting.

Very well made and good instructions. Worth the hefty price believe it or not. Take your time tapping the pin, small taps only!
