Just wanted to throw this out for all you fellow addicts a enthusiasts, who if like me are constantly cleaning your own guns, persistent about changing springs, and asinine about my gun being cleaned everywhere. Lol.. For those of you who struggle from time to time removing your FPS, this little tool is an absolute must have. Its made by SDM is only $20, and worth every last penny. Trust me if you use it once you'll use it 100 times. TWF, you may actually need this for your V-Bob lol. FPS isn't tight but lets just say it needs to be straight when you install it lol.
