This was my first side charging upper and I can't say enough about it. I really like the ease of cycling the bolt once the complete unit is together. I had a hard time initially as I was trying to cycle the action with only the empty upper. Once together the action works very smoothly and easily. My only complaint is that the upper, which cycled the bolt easily, was difficult to use with my reaction bar to install the barrel. The inside of the receiver was very slightly undersized and had to be filed to get the rod to be inserted. Once assembled though this is a great upper and I love the side charging handle. Tolerances can be a real pain at times, but I'd rather have it tight than loose. Everything else about the upper was great and worked flawlessly. Fit and finish were perfect with the one minor exception of the inner fit on the rod. Again, the bolt fit ok so it might have just been my rod. I highly recommend this design and will definitely use it again on future 9mm/40 S&W builds.
