So my new 16" midlength ejects all brass in the 1-2 o'clock area. I thought it was going to be a piece of pierced primer that I found under the extractor. I stripped the bolt, cleaned everything, relubed, and it still ejects to the front.

Rifle - Sabre/Talon 16" mid, Bush A1 upper/bcg, RRA lower/6 pos stock.

Ammo- My reloads using 60Sie/H322 and 77Sie/N140

The rifle functions and shoots great. It just likes to kick the brass forward.

Any ideas?

And the problem is?

Not a problem really. I was more or less curious, as my other 3 rifles pile up brass at 5:00.

Long as it works....don't worry about it. I have one AR that drops 'em at 3:00 at my feet, the other two go about 5:00 a few feet away. My Garand will throw 'em up and forward and they dance off the front handguard about half the time. All of them work 100% so I don't care. You can fine tune ejection like mentioned above, but, if the all eject, why?

That's where my A1 throws them. Since I don't have a shell deflector, I ain't complaining.

Thanks for the help. I think I'll choose not to worry about it.

Just for giggles look at the forward assist/shell deflecter and see if it isn't bouncing off of it. My bud has an M4gery that is brand new and in the break in phase he was throwing brass forward. We noticed there were marks in the forward assist (technical term for raised section inserted here ____) and that the shells were actually bouncing off the "bump" so hard that they were being thrown forward. My diction here is lacking and I apologize but just check it out and see if it might be a possiblity.

I have had cases eject in diferent places depending on the ammo. Some front, some back, some in between. I haven't chronographed any of the ammo yet to pin down the differences to tell why the various rounds are so diferent.

?????? Yes, no, Maybe??????

But I'm with you that specify it means that the buffer is not stalling out at the rear of the stroke, and allowing the case to be pivot off the bolt face rearwards. Too fast of a rearward stroke with the buffer being rebounded off the back of the tube is what Tweak is pointing out. But with the cheap BB filled buffers still being sold, the cycle stroke could be correct, with the cheap buffer lacking any rear dead blow effect and causing the problem.

My 11.5/5.5 throws xm193 and wolf about 7' forward and pmc about 5' to the side. This Ar has a Colt 4 position stock assy. It seems like it kicks more since i dissassembled and reassembled the barrel recently. If i pull the buffer out will there be any markings to suggest overfunction? Any thought s on this appreciated. Oh, this is a slick side upper.

That’s what my sexual therapist says too.

first, let me ask, how many AR-15s do you own ?? shoot ??

i have 7 that i shoot regularly, they all eject the brass differently, the only one that throws brass forward is my newly converted piston 6721 upper !! it did that even before i had it converted.., my theory is the actual finished shape of the deflector & it's angle.

Tweaksaid: "cases bouncing off the brass deflector (either version of it) is not the definition of forward ejection. cases that bounce off the brass deflector show the rifle is working correctly."

Brass deflector? We don't need no stinking brass deflector! I like it when the brass hits me in the face.

Maybe that's why I get grumpy someitmes.

Most of mine bounce off the deflector and end up at 1 to 3 o'clock position, depending on the ammo.

My carbine tosses the empties at exactly 3:00 most of the time (about 10' away) and very rarely it will throw them forward a little. My 20" scoped AR throws them wherever it feels like. I find cases at 6:00, 5, 4, 4:30 anywhere from 2'-8' away. Both of them work perfectly, never a FTFeed or a FTE. I dont' see the problem if it works reliably. MJD

Tweak said: "all AR/M uppers have a brass deflector built in."

True now. I was thinking of the A1, and it was a late night attempt at humor.

My new middy build does the same thing! RRA barrel,Bushmaster A1 upper and BC, Armalite 4 position stock. It seems there is some similarities. I wonder if its due to the ejector?

Sounds like its an AR trying to be an HK. The roller lock series spits them out at about 2 o'clock. Maybe its begging for one of HK's AR mags??? Seriousy, I wouldn't worry about it...although most AR's keep them pretty far back.
