Product Details
This adapter lets you mount a 407K or 507K red dot sight onto your Glock 19, 17, or 45 MOS. It's a straightforward piece that handles the fitment so you don't have to overthink it. Just note it won't work with the 43X or 48 MOS models. If you're moving up to a red dot and already have one of those compatible Glocks, this is a solid, no-fuss way to get there.
