6/3 Sight with 20” Barrel
Guys I’m brand new to iron sights on ARs so please keep in mind I need this dumbed down to a very basic level. I have a 20” barrel upper and I have a carry handle that a friend gave me. It is what he calls a “6/3”. I was reading a little and it seems like the 6/3 sight was meant for a 16” barrel and an 8/3 is what I need for a 20” barrel. Can anyone tell me if I can still use the 6/3 sight I was given or if I just need to get an 8/3 sight for my gun. Thanks!
