"This is truly a great scope. I bought it a few months ago for my JG S-System M4, and it's helped me absolutely dominate the field. The 2X zoom is ideal for medium- to high- powered guns, because you can take guys out at long range, while retaining the ability to quickly identify and eliminate targets at close quarters. Also, after spending about twenty minutes adjusting the position of the red dot, I haven't had to touch it again. The seven intensities are perfect for both day and night battles, and the lens covers are a nice bonus. This thing gets lit up all the time, and I still haven't seen any scratches or cracks on the front. HIGHLY recommend."
