If you're in the maket for a medium, tube-style red/green dot, this is the optic for you. I bought this optic feeling a little iffy about the quality of build but was quickly proven wrong when I obtained it in the mail. It's a sturdy and unique looking and is a great addition to any rifle. And if you don't like this one, get the smaller cqb version or the 4.2 inch version!
-great for the price
-sturdy metal construction
-cool little flip-up covers
-comes with a cantilever and a low profile mount
-finely adjustable, lockable turrets
No cons that i can think of. If you have a fifty dollar budget for a red/green dot sight then I would HIGHLY suggest this to any fellow airsofter. You really get a great bang for your buck!
