Just what I needed

Pluses : price and completeness.Minuses: Screws themselves are the same screws provided with Holosun optics. They almost look like they are metal injection molded instead of cut from rod stock. Would absolutely trust on regular mounting, but might look at sideways if it’s on a pistol slide. If the slide had great recoil abatement, and the fit fit tightly, I’d probably still rock it on a pistol slide. If it’s just the screws securing it that would be a no.

Useful sized screws for mounting optics

The media could not be loaded. Disappointed. At $18 (time of review) and a lot of varying screws, I thought I would have at least one RDO combo that would work. Nope, even the size I needed did not fit right or was not long enough on three RDOs mounting the adapters to different slides and different RDOs to different adapters. I ended up using the screws left over from other optic mounts like I usually do. I'd rather look for specific screws to mount critical duty-type optics. I cannot recommend these as I could not find any to work with my applications.

Basically threw $20 at my problem and solved it. My kit had the m3.5 screws that I needed which aren't listed in the description as of writing this. The screws are well packaged and labeled. Seems to be a bit of a problem with the lack of standardized optic cuts and screw sizes so this is a welcome addition to my supplies and I'm glad to have it.
