Just what I needed

Useful sized screws for mounting optics

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.

Like the title say, its got them all. This set has come in handy several time. A++

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.

If you know what this is, get two asap. Possibly the best value on Amazon. Hurry and snap it up.

Nice assortment of common sizes. Would have been nice to include 3-56 or 2.5mm as well for completion's sake although that is an obscure size for red dots here in the US so it's not a big deal. I imagine most people will be looking for one particular size but if you have a large collection of freedom dispensers and optics a set like this is always great to have around, specially if you move sights around between your toys often. Good product.

Clearly labeled, well organized, and a real saver for when you lose a screw
