Replacement Screw Kit for Micro Red Dot Sights (Incl. Redfield Ace)

Published on 05/31/2025•Product Idea Validation / New Product Ideas (Non-SaaS)

A small kit with a variety of common replacement screws (like M4 in different lengths such as 6mm, 8mm, and 10mm) that are compatible with the Shield RMSc footprint (which the Redfield Ace likely uses) and other popular micro red dot sights (like the Trijicon RMR or Docter/Noblex). The kit could also include a Torx driver bit (T8 or T10, which are commonly used for optic screws) and a small tube of non-permanent threadlocker.

This would solve a common and frustrating issue for optic owners, allowing them to quickly replace lost or damaged screws and get their sights working again. It saves them from the hassle and time of hunting down specific, tiny screws and provides a convenient all-in-one solution for common micro red dot mounting needs.

They will be 4mm screws, this from what I have found is a shield rmsc footprint for the optic. Something like these would probably work. https://preview.redd.it/ewcax2hgm04f1.jpeg?width=120

Do you need the screws that go into the slide. I'd strip the pistol and take the slide or redot to ace hardware and figure out what screw you need.

Too bad Redfield isn't made by Leupold anymore. They were exceptionally nice optics 2008-2021.
