I built my first 3 gun rifle pretty much exactly like that one. The only differences were a S3G trigger, Miculek comp, micro gas block, and 1-4x scope on mine. I shot 5 or 6 matches last year with it, zero malfunctions. I shot well with it. I really like that handguard as well. I kept the rail on the bottom and put a ladder-style rail cover on it. I used it both as a gripping surface and as a sacrificial piece if a stage required resting on concrete or some other rough surface.
