High Exposure 5,662 Posted September 16, 2021 Does anyone have an 870 that has a receiver that is factory tapped and/or pre-drilled for a top rail or optic? If so, I need a measurement from the front edge of the receiver to the center of the first hole. I am having my receiver (that is not pre-drilled) modified to accept an Aridus CROM and need that one measurement to get started. Thanks! Quote Share this post Link to post Share on other sites
