I went through the optics list (in the BHD procurement google spreadsheet) and summarized how to build them.
The red ones are what we need to purchase. Because of the strange height of the LMR mounts, the post needs to have none half-integer inch heights.
They need to be designed as the usual SS posts are not designed to be vac compatible (not because of the material but the design like screw hole venting).
We also need to check how many clean forks we have.
-> The components were ordered except for the custom posts.
