All useful and very helpful info guys.....thanks alot!!
I don't have an upper yet, but it'll be a flat top for sure...the bottom is a stag...I'm thinking of going the del-ton route, seems to be good quality with good price.
Where do you guys recommend purchasing sights, both reflex, and BUIS?
There's a ton of places online, so much that its almost discouraging looking at all the places....but then again, that's half the fun!! Lol
