The Co-witness Ready Optic Mount (CROM) is a direct mount for
attaching an Aimpoint Micro (H1, T1, H2, T2) to your Remington shotgun.
Using the existing drilled and tapped pattern found on many factory
Remington 870s, 1100s, 11-87s, and the VersaMax, the mount eliminates
the need for a picatinny rail by directly mounting the optic to the
receiver. This allows the optic to sit much lower, providing a
consistent and proper cheek weld.
The CROM utilizes an XS rear ghost ring that is adjustable for both
windage and elevation. This gives you the ability to co-witness the rear
ghost ring and an appropriately sized front sight with the red dot,
allowing an emergency backup sighting system in case of optic failure.
Front sights from XS, Wilson Combat, Vang Comp, etc that are designed to
work with ghost rings will be compatible with the CROM’s rear aperture.
Front sights with a height over bore (top of the inside of the barrel
to the top of the front sight) ranging from 0.67" to 0.75"should be
able to achieve a usable co-witness.
This particular model sports the preferred Ghost Ring setup of legendary shotgun instructor Rob Haught. The top half of the XS Sights aperture is milled off, resulting in an open U notch. The aperture is then deburred, sanded, and parkerized. This modified aperture allows for quicker sighting and a cleaner sight picture when using a red dot optic with the CROM.
If your Remington shotgun is not drilled and tapped using the Remington pattern, consult a qualified gunsmith.
Covers must be removed to work with the H2/T2.
Note: The zero of a shotgun is very dependent on the specific
barrel and ammunition used. While the XS rear sight allows for a wide
range of adjustment, it is possible you may need a taller or shorter
front sight depending on where your specific gun and ammo hits. We
cannot guarantee that every shooter will be able to achieve a perfect
co-witness with their exact setup, we can only offer guidlines based on
what we have seen in testing.
