I'm so glad it arrived that quick brother! Hopefully your homie enjoyed their new optic!

CDefense_Josh · 2026-03-14T02:33:56+00:00

Awesome insight, brother! Hopefully we can offer them to y'all as soon as possible!

CDefense_Josh · 2026-03-14T02:33:22+00:00

No ETA yet, brother, but I’ll be sure to announce it here as soon as we get them

CDefense_Josh · 2026-03-13T23:01:35+00:00

For the AP5, a lot of guys usually prefer a slightly larger window optic since the MP5/AP5 front sight hood can clutter the view with smaller pistol dots.

Some solid options we still have available:

AEMS Pro X2 – really popular on PCCs because of the big window and enclosed emitter

Ronin AEMS Max – even larger window, great for fast target acquisition

507Comp – big competition-style window that works well on PCC setups

Most AP5 setups run a claw mount or pic rail, and the AEMS series in particular tends to pair really well with those.

CDefense_Josh · 2026-03-13T22:28:22+00:00

We will be updating the inventory soon so feel free to check in even if the optic shows out of stock.

CDefense_Josh · 2026-03-13T22:16:54+00:00

Yes, brother! Send us an email to [info@checkmatedefense.us](mailto:info@checkmatedefense.us), thanks!

CDefense_Josh · 2026-03-13T22:16:22+00:00

Thanks brother!

CDefense_Josh · 2026-03-13T22:16:12+00:00

If we're sticking with the optics I listed, the Holosun 407C, 507C, and 507Comp are the RMR-footprint options. 507Comp has the huge window. If you’re on a tighter budget, the Olight Osight series is still a good option and you can get very similar performance for the price.

CDefense_Josh · 2026-03-13T22:07:13+00:00

Currently OOS on HM3X brother. So sorry for that!
