Some tips from the 6mm Badger on how owners of gas blowback rifles can clean them properly... "In this video, I show how I clean and maintain my Tokyo Marui Mk18 MWS gas blowback rifle after a game day.
This video follows the same style as my previous GBB pistol cleaning guide, but this time for a full AR platform GBBR — and most of what I do here will apply to any gas blowback rifle in the MWS or standard AR-style format.
After using the rifle in Southern California’s dusty conditions, it needed a good post-game strip down. I disassemble the MWS, clean it with cotton swabs and Q-tips, apply silicone lubricant to all key parts, and reassemble it for peak performance.
Proper GBBR care is the key to keeping your rifle consistent, snappy, and gas-efficient. Let me know how you clean yours and if you do anything differently!"
