Our take: Adam Arms has been providing excellent retro-fitted gas piston systems for the AR-15/M-16 rifle in order to convert them into modern day platforms that will continue to be relevant for many more decades to come. It is because of that ingenuity that Madbull is proud to announce the airsoft version of the Adam Arms Gas Block Kit system. Each kit comes with the famous Adam Arms gas block, interchangeable gas tubes and 10-inch gas tube for mid length system. Each gas tube features a built in spring guide, and the gas block is built with a RIS rail for attachments. To mimic the real steel version, this airsoft kit comes with a switch block so the user can simulate adjusting the amount of pressure that’s routed backwards to cycle the bolt. Obviously, this feature serves no function for airsoft, but it’s a unique feature that displays Madbull’s attention to detail.
