Dave,
When you're doing the review (or whoever does the review), please make note that you really need to cut one of the end guards off the molding block and then use a fine saw to cut the sights off at the base. The 3D printing supports then can then easily be clipped off with some flush cutters. If you try removing the sights individually, they are so crowded on the block that you can't readily get clippers in there to cut them off. The material Gaspatch uses in their 3D printing is really tough, but these sights are really fine and can be broken without much effort. I know that because I tried cutting off the just the two I wanted and ended up breaking one and losing a couple more which broke off during my attempt to snip the others.
Based on pictures in the WNW Salmson USAS instruction manual, I cut off the sights on the kit Lewis guns, drilled holes in their places, and inserted small lengths of .4 mm brass tubing. The Gaspatch sights fit perfectly into the tubes on the right gun, and I left the tubes empty on the left gun as shown in the photo. Unfortunately, I don't have any pictures, and my storage for the assembled MGs (a medicine bottle) let them rattle enough that the front sight broke.
