LXV Designs show how one can assembly the Airsoft AT-4 tha they made with project files design available for 3D Printing... "An Airsoft launcher replica AT-4 with almost the same manipulation as the real counterpart. The only functionality that differs is the rear safety ring pull. It is made for a 40mm airsoft grenade by using an included adapter (adapter may not work on all grenades and you might need to model and print one for your specific grenade) This means it can launch anything including the well known Taginn rounds.

This is a basic assembly guide, please follow this alongside PDF guide that is provided within Project files."
