A step by step instruction on how to effectively clean the gas system on a Browning Maxus. Tools: 1. Green Scotch-Brite Kitchen pad. 2. Gun Oil 3. Gun Cleaner 4. Cloth 5. Nylon Brush (optional) Note: Never use a steel brush on any of the gas components. 1. Please refer to How to disassemble your Browning Maxus in order to remove the gas system from the firearm. 2. To simplify cleaning the gas system, separate the gas piston from the piston sleeve by pulling them apart. Note: There is a small lip that holds the two pieces together, you will have to pull firmly to seperate. 3. Spray the magazine tube, gas piston and sleeve with gun solvent and brush them thoroughly with a nylon brush to remove any deposits. 4. Spray the inside of the gas piston. A green Scotch-Brite kitchen scrub pad works best for removal of heaving carbon fouling on the tube and inside of the gas piston. 5. Complete the cleaning of the gas system by applying a very light film of oil to all parts for protection and lubrication. Note: Do not place large quantities of oil in the action, excess oil can run back into the wood of the stock softening the wood and consequential loosening of the stock. 6. Reassemble the gas system by snapping the piston sleeve into the gas system. Slide the gas system back onto the magazine tube.
