The Co-witness Ready Optic Mount (CROM) is a direct mount for attaching an RMR or Aimpoint Micro (H1, T1, H2, T2) to your Beretta 1301 Tactical Shotgun, Remington, or Mossberg shotgun. The CROM replaces the factory plastic rail and rear sight and directly mounts the optic to the shotgun’s 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 the factory front sight, allowing an emergency backup sighting system in case of optic failure. Made in the U.S.A Covers must be removed to work with the H2/T2.
Rob Haught Mod: Inspired by the preferred Ghost Ring setup of legendary shotgun instructor Rob Haught, this modified aperture allows for quicker sighting and a cleaner sight picture when using a red dot optic with the CROM. 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.
Notes: 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, we cannot necessarily guarantee a perfect co-witness. However, all testing has shown excellent usability with a variety of loads and guns.
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.

One of the *best* additions you can get for your 1301T. Makes aiming an afterthought and re-acquisition of targets a breeze. Being able to tack on one of BTO’s promo codes is just gravy.

Super easy to install. You’ll need a T15 Torx bit to remove the factory rail and rear sight. The ghost ring sits at the same height as the factory one did. If you want a red dot and BUIS, you’ll need this.

I’m thoroughly impressed with both the company and the product.
Mossberg 590 and Trijicon RMR Type 2.
Hardest part of the install is getting the factory ghost sights off the shotgun while everything else was easy as pie. It holds zero perfectly, and with the Rob Haught custom rear notch sight getting everything to line up and zeroed for two different shot types is simple. If you have a shotgun compatible with this mount it should be the only option you ever consider.
Props to Big Tex for including a constitution and prompt/updated shipping.

Couldn’t be happier. Everything lined up perfect. Love the fact that they included THE CONSTITUTION, in the package. Would definitely support them again. Holosun 507 on a 590A1.

Excellent addition to your Beretta 1301. The fit and finish are perfect! Instructions are clear and everything needed for the installation is included. I put a Holosun on top of mine and everything lines up perfect and was super easy to install. .
