Well I purchased a 16 inch CIV tactical upper back in September and was kinda skeptical at first but after talking to Dustin who sounded like a standup guy and knowledgeable on his builds I purchased a dissi upper and was surprised by the quality. I thought it was such a great purchase I decided to pick up one of his pistol uppers. I haven't tried this pistol upper mainly to just getting everything put together, but if runs like its bigger brother I know its gonna be quality. Thanks again Dustin. Sorry for the bad cellphone pic.
7.5in barrel with kx3 muzzle break with 9in rail, went with a BCM charging handle and BCG.
