Not unless they mixed it at the factory and got the headstamps wrong.It almost sounds like you had 223 and 556 mixed up in the same pile or something? lol
Then again I have seen some of that phenomenon, particularly with guns that had brakes or no flash suppression, etc.
5.56, see the link for specsIs it a .223 or 5.56mm barrel? Curious.
The barrel temp may be an issue, when I first noticed it it did seem to be more frequent after the first mag or two. Last weekend it seemed more consistent so I was thinking gas block issue, but like I said I don't have a lot of hands on with monkeying around with an AR. In the past it's been someone else's rifle so I was basically shooting it and handing it back. Last weekend was also all indoor so no major cold temps.
Thinking about it,this may fit. It's not a big deal to change that. The gun isn't MA compliant anyway, and doesn't need to be.It’s the muzzle brake. It’s due to trapped gasses and unburnt powder.

And I'm shooting the muzzle device SA shipped it with.

unburned powder on the muzzle brake isn't going to explode if ignited by a subsequent shot, so it wouldn't account for the louder blast. It would just spark a bit, not that there would be enough there to even notice anyway. And why would it be different when he's inside vs outside. I can't figure out where the gasses are supposedly trapped either, they have to go somewhere and it should be consistent if that's cause.

The other day I got a mini fireball out of my aero mid builds with a VG6 FH on it. I basically ran a few different kinds of 223, it was just that ONE shot out of maybe 200 rounds of
ammo. It never happened again. No sound increase but the flash/sparks was noticeable.
Both the Gamma and Epsilon are considered a brake/comp hybrid. They just also happen to do a good job at suppressing flash as well. That’s why you’ll get an intermittent flash
I have the Delta, though.

boom and flash are unburnt powder reaching atmosphere. Increase barrel temp will provide more Gibbs free energy and thus speed up burn rate, not slow it down. I do not see any way a hot barrel would result in more muzzle blast. If anything other way around. Regardless barrel temp is a relatively small component to burn rate it’s not going to make a huge difference unless the powder is super temperature sensitive.
either way this rifle definitely sounds defective. It should be massified with a pinned stock and brake then sold for a low price to a subject of the commonwealth.
So despite too many decade shooting I only got my first AR recently. Nothing too fancy, just something I bought, not built, an SA Saint Victor. But it's doing something weird that I'm guessing someone with more knowledge of the AR-15 platform has seen before. At first I thought it might be the ammo, the bulk Winchester 55gr 5.56, but over the weekend I had someone run 30 rounds through their AR and it seemed not to have any issues.
What's happening is that some of the time when it's fired the sound is unusually loud and there is a lot more flash. At first it was only every 5 to 10 rounds, but last time out it seemed like it got about half way through the 30 round mag and then it was every round.
I'm going to get a different ammo and see what happens, but I got a fair amount of this bulk ammo amnd, well, we all know what the ammo situation is right now.
What I'm hoping for is a "ya I've seen this lots of times and you just need to ..." kind of answer, but any ideas on what I should look for would help. Thanks
Serious question not busting your balls, but what type of earpro are you using? I’ve seen lots of guys with the bigger ear muff styles trying to get a cheek weld and it ends up pushing the earpro up off their ear a little. Could that be the case?
Agreed it doesn’t sound like that’s the case as OP stated, but my thought was the sound pressure (unexpectedly with no or failing earpro) may lead one to think they’re seeing a bigger flash in their head just from the shock of the sound.That would cover the sound issue but not the increased flash he mentioned.
I'll throw another nod toward it just being irregularity in the ammo's charge. Even if he had a blocked gas-tube, presumably a non issue on a new rifle, it would only cause a minimal amount of extra gas to exit the barrel and shouldn't even be perceivable. But the rifle wouldn't run for shit. Ammo is the only thing can think of that would cause both problems with no functional problems.
A side note.... I -have- run into this phenomenon with handgun ammunition, before. I suspect that some of it may even be based on things like maybe the powder position in the case or something like that and how it lit off. I wish I had a chrono at the time...
Awhile ago I was shooting Privi .357 Sig FMJ ammo. As some of you probably already know, that shit is loud to begin with. My experience with the ammo was something like..
pow pow pow. pow pow.... BOOM!!!!!!! (with accompanying huge fireball) the first time it happened I almost dropped the f***ing gun. After I realized the gun didnt blow up I was laughing pretty hard for a couple minutes.... It maybe happened like, once per magazine, say once every 10, 15 rounds... but it was there... and definitely noticeable.
loose floor sweepings can be like thatA couple good comments but some of you aren't reading, or maybe I'm not being clear.
The ammo is legit, sealed box from Shooters, headstamp matches. All from the same box. And Ammo was my first thought until the problem didn't happen in another AR.
What I describe happening is see and noted by all at the range, so this isn't my ears, or eyes, or some weird expectation of what an AR sounds like. And it's the first one I've owned, not the first I've shot. Seriously guys, I've been shooting since I was 13, thats forty years. There has been more than one AR in my hands. Although I do like the full auto SCAR more.
The rifle is completely stock and was new when I got it, also from Shooters.
Specs, muzzle device, here you go SAINT® Victor 5.56 AR-15 Rifle - Springfield Armory
I can't emphasize the difference between a "good" round and a "questionable" one. Everyone notices the change in volume and it's spitting fire. It's not subtle.
Otherwise it runs flawlessly, no ftf or fte and goes bang every time, a lot more carbon build up at the muzzle, but otherwise ok. And while I'm shooting a short range, the accuracy does not seem to be affected.
If it is just the ammo, it's the crappiest QC I've ever seen.
