Leupold DeltaPoint Pro riser

This is a super quick and dirty solution to saving $30+ USD, since Leupold's official riser is way more than you would expect for a slab of aluminium. This is also much lighter.

Requires some longer screws as they must pass through the riser and thread into the cross slot mount. I am unsure of the thread size, as I just looked around in my spare screws bin in the garage. Around 25mm in length is good for absolute co-witness. 28-30mm for 1/3 lower co-witness.
