AR15 ejection question

[jcaoloveshine]

Troy 16" Alpha Upper 1/7 Twist Midlength
A2 stock with full-length buffer spring
584 rounds since cleaned the bolt, freshly lubed.

Normally ejects at 2 o clock. Shooting 55gr Freedom Munitions 223.

Was shooting the rifle leaning on the PVC pole of the brass net (pic below) with maybe 1-2" of clearance between the gun and the net.



Had a perpendicular stovepipe with rim against bolt. Was thinking that the ejection was either obstructed by the stiff net, or bounced back from the net into the chamber since it was so close.

Was able to duplicate the issue.

Is this something to keep in mind for AR15s? How much distance do you need between the ejection port and a barrier?

I seriously doubt the stove pipe shell bounced back into the chamber. Things like that just don't happen. I'm not buying into that one.

When I was duplicating the issue, I did actually notice on the last round that it bounced off the net back into the chamber.

On another round, it was again caught 90" by the rim. Not sure if that just didn't have the room to clear due to the net.

Once I moved further away, no issues. Never had this happen before either. Just wondering if there's some distance rule or something.

Never heard of or seen. How exactly are you firing safely & watching to see spent brass eject, fly several inches, hit a barrier, bounce back, fly several inches and end up IN the ejection port before the bolt closes? And gave it happen more than once. That's like a miracle... twice.

Check your ejector & extractor springs on your BCG.

I used a red dot, so I held it steady after centering on a target and then watched the port.

First time I duplicated it the casing seemed to have bounced back in (the net was only about 1-2" away). That was probably just a random occurence.

Second time the casing might have just got caught against the net on the way out, which caused a 90 degree stovepipe.

I'm wondering if it's plausible that if you have a barrier that close to the ejection port that you might be able to interfere with ejection. Most likely situation I'm guessing is that it somehow blocks the casing from getting out fully, which causes it to get stuck against the bolt.

Or is the AR15 not supposed to be affected by something like that?

I have 2 different style Brass Catchers........never once had any problem with brass bouncing back into the chamber or failing to eject. And that includes forgetting to empty the bag. The only thing that did happen was some of the brass got dinged, but that was from banging into the other brass. Hard to tell what caused your issue.

[BarrettM99]

It does happen. Travis Haley taught us the reverse bolt override malfunction clearance drill for just this occurrence. He said that it happens when you're shooting close to the ground or against something and the brass bounces back into the rifle. But he never mentioned it looking like a stovepipe.

Either way, very rare occurrence. I've never had it happen and I've been shooting a long time.

I have shot really close to/under barriers and in urban prone where my brass was ejecting directly into the ground. Never had this happen.

[Calico1404]

It would be impossible to not only make in back into the receiver, but in the correct direction and seated enough to stove pipe? I say no way science supports this. 1 in 100,000,000. maybe

[glock_this]

Agreed... I think it is a BCG issue. Like I said above, all of that happened before the bolt closed? More than once? I need to see a video

I suspect, the round is not ejecting = stovepipe.

Once I got batch of the Freedom Remanufactured, my AR would also eject out to the 2 o'clock. Every other brand of .223/5.56 Tula, Federal, Colt, IMI, PPU, PMC would eject at the 3-4 o'clock position.

C'mon OP, it's like saying there r other life forms in the universe and the earth is round? We all know earth is flat!


J/k it happens all the time when I use el cheap brass catcher with weak ammo. Brass either never leaves or it bounce right back in. Remember spent case is about 1.5" long, if it does not have enough room to clear, it's not going anywhere.

I don't understand why this isn't obvious and why people are talking about casings bouncing in and out of receivers.

If you obstruct the ejection port such that the case can never clear the bolt, the rifle isn't going to just blast the case through the obstruction, it's going to malfunction.
