Buddy of mine build a new AR and took it to the range. he was telling me his brass would hit off a triangle piece after it ejects. I thought he meant the forward assist, but no, it wasnt. http://www.cncguns.com/images/ar15_drawing_a3upper2.jpg shows a cad drawing with the piece in question. it's the part between the ejection port and the FA area. what is that piece for?

thanks guys!

It's called a "brass deflector".

Yep ––- I have several Ar's ––––- my old Colt M-16 604 "tribute" rifle with a slick sided upper, as well as my modern DPMS Sportical (also slick sided) both throw the brass 10' to the right and back.
everything else with a brass deflector puts the brass 6' to the right and front

Why the need? I dont know –––– maybe to help lefties out a little bit

yes, that is supposed to happen. Its sole purpose is so the brass hits it and goes foreward

on a positive note, you may be the first person to ever ask that

It's all good OP. If you don't ask questions, you won't learn. Welcome to the site.

Join date of 2008 and you didn't know what a brass deflector was? At least you came to ARFCOM, the source of all information worth knowing, to find out.

When I first got into AR's I knew nothing.

After u shoot a few rounds, youll get a cool little gold stripe on your deflector
