Hi all. I had some removable weapon mounts in an aftermarket bumper on my 2010, and used it at work with the cadets on some field exercises and range days. It was an absolute blast, and I'm looking to do the same thing to the new 2017. Nothing huge- just 5.56 and 7.62 belt feds or a Barrett on the soft mount, mostly using blanks. No M2s or anything too stout. 1. Does anyone actually use the BoxLink attachment points for anything, and might they be of use for a project like this? 2. If not, I'd rather not replace the factory rear bumper, but I'm not opposed to putting in bed rails or some other structure like a roll bar setup or rack. I would like to not have anything permanent installed that would get in the way of using the bed for normal chores. Any thoughts or suggestions? Thanks!
