Following the popularity of their Beretta 1301 Co-Witness Optic Mount, Aridus Industries has turned their attention back to the Remington 870 and has announced pre-orders for their CROM (Co-Witnessing Ready Optic Mount).
I got a chance to play with the CROM when we tested it on my Vang Comp 870. Click here to read the review on the Vang Comp 870.
The CROM allows the use of Aimpoint T1 or similar optics to be mounted on your drilled and tapped Remington 870s. The CROM is designed to work on the Remington 870 Tactical Express models which have tall front sights and a picatinny rail. You replace the factory picatinny rail for the CROM and now you have an optic that co-witnesses the irons.
The CROM comes with an XS rear peep sight that is fully adjustable for windage and elevation.
Right now the CROM is on sale for those who pre-order. Click here for more info.
