https://www.reddit.com/r/Nerf/comments/q412iw/rod_seal_longshot_experimentation_details_in/ Longshot rod seal (instead of pusher piston seal) breech pusher_01 was the one I used, that eventually snapped. pusher_02 and pusherreinforce should hopefully hold together a little better (oring seat a little more narrow also). Uses 3.5mm (28mm ID) o rings for lipless base, and 2.5mm (14mm ID) o ring for the rod seal at the breech
