This BCG is a perfect match with any Tokyo Marui MWS M4 variant, it is on the lighter side, so you will loose recoil when adjusting the FPS lower. The general ROF will increase and adjusting the FPS higher will slightly boost the overall lessened recoil. The "FDE" coating does stand out nicely compared to the stock TM BCG in my opinion. I have to give credit where it is do, this AG BC and its adjustable Gen 2 MPA nozzle are very reliable and you will gain approximately 1 juole of adjustment. I have to recommend both these parts if you an avid TM GBBR M4 user.
