I have two ratings to give this, the Magnifier recives a 5 star. The Square sight is perfect for the Holosights! i love the magnifier, and it is just what everyone needs for field use!
Now for the base.... this recives a 3 star. it would have only recived 2, but since the base has the cool flip out feature it gains that extra star. Since you need the base to mount the damn thing i had to toy with it to make it work! The base is just too small! (half of a cm small) I have toyed with it long enough, i am running to my local ACE Hardware store to retrive a longer set screw. The mag will separate from the base as well, so once you get the base mounted, you only have to take off the mag! HUGE PLUS
square mag box
flip down to switch to CQB
rubber eye guard
i.e. takes way too much time to set
doesn't sit flush to RIS
Rating: [4 of 5 Stars!]
