my M4gery ejects at 2:00 most of the time .... but once in a while it does the 4:00 thing.
I like the 2:00 ejection... any way to make it that way consistantly?
And does anyone know the reason it does one or the other?

All of my AR's do this same thing, 90% of the brass is at 2:00, the rest at 4:00. I have no idea why but it has never bothered me.

Extractor loses grip of the spent case too early and it fails to hit the brass deflector...

I thought this was going to be a thread about nocturnal emmisions, and was going to suggest the general forum.

Reliably at 4:00 for me, though.

I thought it was about military aviation.

All mine throw at 2 O'clock consistantly. Try using an o-ring under your extracter see if that has an effect one way or the other.

A friend of mine built his own AR and it ejects at 2:00 with LC, but Wolf it kick them out at 4:00? Maybe it has to do with the higher pressure ammo?

Hmm... I always seem to find the brass at 5 o'clock, approx 6-8 feet away and fairly even with where I am standing.

The only time brass went to 2 o'clock was when I trimmed a couple of coils off the ejector spring. It tossed my brass in front of the firing line, making me wait until brass call, so a new, std length spring went back on.

I had a salty Marine ask my where my brass went right before the first match. I pointed at the ground just across the line at my 2 o'clock and he said "good, then we won't have any problems." I don't mind waiting a wee bit until brass call. I don't need my ass kicked by a retiree.

The story is in the Washingon Forum, go there if you are interested. I'll miss him terribly.


But getting back to the ejection. If you're ejecting at 2:00 you are getting a bit of overfunction. Brass should be landing between 4:00 & 5:00.

I have had brass eject in different directions depending on the type of ammo and what gun.

Once again, Armalite's Tech Notes to the rescue.

Read all about it here:

www.armalite.com/library/techNotes/tnote34.htm


Though this is written about the AR-10, it applies equally to the AR-15.

Hats off to Mark Westrom for publishing these.

thanks for the replys..... I want to try some wolf somtime just to see how it functions, since its a lower velosity ammo maybe it will eject back more in my rifle.

Well, the guy's a prick then.

Everyone knows ARs spit their brass to 4 - 5 o'clock. That's why everyone wears long pants.

I like being able to pick up my brass when I'm done shooting. I shoot pretty fast in slow fire, and with my brass going to 4 o'clock, I can pick it back up after I'm done in offhand without bothering anyone. When I shoot slow prone, I set my stool up as a case deflector and open the front flap, so that virtually all the cases end up in it. The few that bounce out fall right by my right elbow.

The standard HP mod to make your brass land at 2 is to trim your ejector spring. Depending on the spring, I'll trim between 1.5 and five coils.
