The Propane Adapter made completely of metal and has a silicone oil port to make lubricating the gas easier. The metal construction is more durable than plastic because as the gas flows through the adapter it chills the adapter making it more susceptible to breaking off or cracking.
This adapter features a miniature silicon container attached to the side of the valve, so now you will now be able to charge your GBB magazines whilst lubricating them with silicon all at the same time. A specially designed chamber is designed to allow the silicon to mix with the propane gas when not in use, whilst at the same time preventing the silicon from leaking out of the valve
Please Note: The nozzle of this adapter is not compatible with magazines with extra large base plates. It will not reach the fill nozzle on guns such as the WE Hi-Capa. Also, propane is heavier than air, do not use indoors. Propane is poisonous if large amounts are inhaled, and extremely flammable.
