Brass Deflector

Hi Friends,
I am new to the AR-15 world, bought a Rock River Arms NM4 for competition. Took it out to the range to try it out and it sure flings brass quite a ways. Bought a Brass Deflector and it's on it's way. Just wondering if there any negatives about using a brass deflector on an AR-15 that I should know about.
Thanks in advance.

What do you want it to do?

The only time I used one was in Army Basic Training. I am left handed and they gave me one. I don't think it was needed and I don't use one on any of my own ARs. When I was going through basic we had brand new M16A2s that have a brass deflector built in on the upper receiver. The basic class before us I assume used A1s that don't have the bump so for lefties the deflector was probably needed to keep brass coming back at their nose.

The ones I used in the army snapped into the hole on the carry handle. If you have a flat top It would need to mount on the rail I assume.

how to shorten the throw

when i shot ar's i cut 3 coils off of the ejector spring. most of the thrown cases shot from the prone position could be reached without moving off of the mat. works for m1a and garand also.

An easy and cheap method we use on the range is to pull the brass strip out of a stripper clip. Bend each end in the opposite direction to look like one arm of a swastika and insert the one end between the ejection port and the ejection port cover. Put on right, it will look like a little brass "L" sticking out in front of the ejection port. Now when the brass ejects against it, it will deflect it enough to not hit the shooter next to you. Like I said, it's simple, easily replaced, disposable and best of all, free!

Jon, it's what I want it NOT to do: shower my fellow shooters with hot brass. Seems like a good idea but I am always conscious about the "law of unanticipated consequences".

Get the brass catcher that attaches to the port, looks like a little fishing net. Eliminates flying brass and makes cleanup a breeze! Also a boon if you reload.

I use a brass deflector on my match AR for the same reason. I've used a plastic type and a thin metal one. What I've noticed is about 10% of the time the case deflects back into the ejection port, causing a jam. Now I use the deflector for the standing position only. I suppose I could try and tweak the deflector to see if I can change the deflection angle, but it's easier to just not use it during a match.
