AR-15 breathing fire out the wrong end?

[Markjz]

I've put quite a few rounds through my AR but today something odd happened.

It may be something I never noticed before as there was poor lighting conditions, but once I started firing rapidly every few rounds I would get a 6" long blast of fire
out of the ejection port. It scared the crap out of me. I couldn't find the casing in the grass and no brass fragment left in the chamber. gun still kept firing fine.
I was using 55gr Remington ammo. not to fond of it

what kind of remington? did you notice odd recoil or report?

sounds like a case head separation.. those usually result in a broken case left in the chamber, but anything can happen

i'm not fond of remington either.

every thing felt normal. I have had to discard a few short rounds before. is was just 55gr FMJ. never had this with wolf or winchester

It happens.



I see it more often on the last round out of the mag since the bolt unlocks a little earlier. And more so if the ammo is loaded with slower burning powder.

Dam that's especially rough for a lefty!

Its where the gas going through the DI system goes, out the right side

I dont know if that's the only cause... But its not a closed loop system.

if thats what the OPs fireball looked like, then that's probably all it was. i was envisioning quite a bit more fire..

I have no idea of the cause, but that is a cool picture.

That is a cool pic .I wonder if a adjustable gas blocks would help?

This one's cooler:



Same day, IIRC.

That pic stirred up a "Is it real, or is it photoshop" thread on Arfkom back in the day....I was famous for 15 seconds.

That looks like one of the G3 k jobs that a friend built when he was working down in Vegas - tricky job getting the recoil spring to work right when you shorten up the back end of the receiver and shorten up the front to K length - AK pistols make a huge flash and loud bang but a .308 that short makes your clothes shake when you pull the trigger!

And thus the answer to another thread "Why would you want a piston operated AR-15?"
