Bought to use with an AK style mount for my ak74 and have had no regrets. Very quick and easy to set up/adjust. Covers I received were not clear and have to be flipped-up or removed during play but no a big deal.
Easy to install and set-up
Good function and visibility
Good price (at the time)
Paid not quite half the listed price at time of purchase (about $28), and looks like that's gone up.
Covers were solid, instead of clear as shown in this picture.
