These are both fantastic shotguns. One does not replace the other. I’m fortunate to have both. The Magpul stock is mounted with a GG&G adapter. It works nicely. I think the Aridus adapter looks cleaner, but I couldn’t find it in stock at the time.
Thanks. I highly recommend installing the Beretta 1301 pro lifter. The difference is it keeps the lifter up and out of the way. Makes reloading super easy.
