Several things
The #6-32 and the #8-40 positive stop screws worked perfectly. The 90 scribe is very sharp, and apparently very hard. The nylon bench block is very well made, and performs as one would expect. I have not had occasion to use the lead shims or the bore mop, buut they appear to be of good quality.

Hard to Find Plug
Needed to plug some holes on my Ben M4 where the picrail used to be. Nice that these plugs have a lip so that even if they came loose they wouldn't work their way into the action and damage something.

Plug screws
I had to abandon my old reliable aperture sight on my Marlin39A in favor of a scope. I was unable to locate the factory screws (carefully stashed away a few decades ago). These replacements fit perfectly. Now the originals can come out of hiding.

Plugging up some holes
I’ve converted several pistols to optics so wanted to remove the iron sights. Ditto with some rifles that I have installed scopes to replace the iron sights. These plugs made my firearms trimmer and sleeker.
