Up next lock up good and bad...stay tuned WARNING camera work was done with cell phone and in my basement. Poor lighting, excessive motion and random shots of chicken legs and a few foot shots are to be expected! I did wear socks to spare the weak. https://www.youtube.com/watch?v=R_bW6Os3Iig another rough video another one: I could not get the rear guard on with one hand and just stopped the video. When your rear guard is in place see if you can slide a piece of paper between the barrel and the wood. should be free floating abd the paper should be able to slip around and through.
