This is an ar308 speedloader which uses a milspec ar15 mag catch, so the mag will be securely locked in place before sending the rounds into the mag. Includes a newly designed pusher tool. All needed files and instructions are located in the attached zip file. Will accommodate up to 25 round in the pusher tray at a time. Tested with hexmag ar308/sr-25 magazines, but should work with any mag designed to fit these platforms.
