I got mine when they were alot cheaper and I was impressed by this scope other than the extremely close eye relief, and the reticle that is nothing like the p4 on larger scopes I have used, made by NCSTAR. It made my m4 shoot one hole groups at 60yds. but mine has way to close eye relief, and if your AR-15 is a larger caliber than 5.56 you might get a closer look at the scope than you want.
Pros: Cheap for what you get.
Cons: Very short eye relief.
