Hi folks! Bought this looker a little bit ago direct from Anino Lokal Philippines. This box is made of Aluminum/brass/copper. These guys have been a pleasure to deal with for the purchase. So, everytime I get new hardware(mechs/atties) I always do a full breakdown with pics and descriptions. **To add to that, a stellar practice with any full mechanical is to always break it down and inspect it before ever putting batteries in and firing. So here we go again......... How it came: First looks of the exterior: Fits well in the hand and is solid. Ultem button with smooth medium throw Brass 510 plate with a copper 510. Negative copper battery contacts/brass plate and negative rods that connect to the brass top plate. Look inside from the base to copper positive contacts. 510 housing and full copper positive switch connections. REAL LIFE exploded view! Switch.
