HK sight jig

This is a remix of a jig for aligning the rear sight bracket on a HK receiver for welding. I've made it so that it is held together with 2 screws. I also make some changes to the shape of the jig.

After printing run a tap through the left jig to clean up the holes. Use 2 40mm m5 screws.

The Fusion 360 file is included.
