DeWalt model DCE560 cordless 10oz adhesive gun circa 2019. This unit looks near brand spankin' new, comes in its original box with all original parts as far as I can tell! Also included is a 20oz extension kit so you can get the big caulk. Runs on a 20V battery which is not included as sold. Retails at Homotion l'Ocean for just under $200, not including the sausage extender.
