If you want to “Co-Witness” iron sights with a red dot optic you will typically need “suppressor height sights” to be able to see the front and rear sights through the glass of the optic.
Additionally, if you are shooting with a suppressor, you will need the taller sights to be able to acquire a sight picture over the length of the suppressor itself.
Ameriglo offers three different height sights for both Co-Witness with red dot optics and, of course, suppressors. This option is also a tritium night sight that “glows in the dark” for up to 10 years - no batteries required. The white dot outline is also very effective for daytime sight acquisition.
XL - .308 Tall from the top of the slide (most popular for most optics)
(provides a clean ⅓ CO-Witness)
3XL - .369 Tall from the top of the slide (used for optics with a thick base - ie, Delta Point Pro)
5XL - .424 Tall from the top of the slide (typically best for longer suppressors.
