ar15 build
 

Im doing my 1st ar build. I have a stag lower and im going to use a stag 16" barrel. How do i know which gas block to use. I am kind of unformiluar with this

I'd take this to the AR forum. That's about all we discuss up there is how to get doomaflickie A to mate with hickeymadoodle B and make the thing go bang.
