I got this on the UTG L96 and with the sun shade on, its about a foot and 5 inches long. WARNING: YOU NEED HIGH PROFILE MOUNTS FOR THIS! OR ELSE THE FRONT OF THE SCOPE WILL BE TOUCHING THE BARREL! even with the leapers high profile mount on mine, there is very little clearance between the scope and the barrel, it looks really nice this way. having a 50mm objective, it allows a little more light in than the 40mm, so you can see a little better at night or in the dark. Leapers gives you a cleaning cloth and a card that includes the most used range estimations and a formula if you want to calculate it yourself. (assuming you know the size of your target at least)
easy to zero
zero-locking feature is nice (stupid friends like to piss me off and mess up my zero)
mil-dot range estimation (helpful if you know your gun's maximum range)
crystal clear lenses
worth every cent
adds considerable weight to the UTG MK96
eye relief is a little short
the front scope cover can hit the barrel if you adjust the focus too far to either side.
can be pricey for a scope, compared to other ones designed for airsoft purposes only.
