For Tactical shooting it is great. I have had for a month and love it. Easy to install and move between weapons. Only product I would replace it with on my SR556 is the MVF-515 from Crimson Trace that would stay on that weapon. Huge difference in price between this cost effective unit and the MVF. Would buy again if needed. Service from AMAZON was great.
