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

Great quality from HDPS! Works great and the singular cross pin secures the block perfectly to the upper receiver. Worked great for my USC to UMP conversion.

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