Brand new BLEW UP IN MY FACE ON SHOT#16

I have a relatively new Sporter II and after initial inspection and cleaning, I successfully fired more than 3 magazines downrange. It is MUCH better than military garbage I was assigned nearly 50 years ago! It is barrel marked 5.56 and eats all ammo without a hiccup (Including Wolf gold).

Glad to hear it. A lot of us shoot Wolf Gold as it is quality ammo, so no worries about feeding with it. Now Wolf steel case, different story.
 
I just did a test on my mid-gas Magpul M&P. I stuffed a piece of paper towel into the breech (no round in chamber) and released the bolt on it, to cause an out-of-battery condition. I verified the bolt was about 1/8" from closed. I pulled the trigger, and the hammer was released. So my M&P will definitely fire out of battery. Color me VERY concerned.

There is a difference between the hammer being released and the ability for the firing pin to strike the primer when the bolt is out of battery.

No need to be concerned.

Relax, your gun won't fire when out of battery. Look at this animation:

Watch as the BCG comes back. Once it's about 1/8" back from the locked up, the hammer is pushed back enough that it won't contact the firing pin. So, even if the hammer is released while out of battery, the BCG won't allow it to contact the firing pin.
 
When testing my Win Mod. 61 I pulled a few bullets and emptied the powder and tried the same experiment. The Mod 61 would not even go click out of battery. Glad so read others are experimenting with their rifles, the knowledge gained is good times.
 
Man Americans have been building guns for well since before we were Americans but here lately I ha e heard about the most guns just "blowing up" .They are all over U tube it's crazy just crazy. Cars too .Got a cop friend who went to an accident scene last week .This you g man was driving down the road and his car just started rolling over ,rolled off the road and into the ditch ! He wasn't hurt either so at least they are making cars more safe even if they aren't if that makes since. Investigate ?oh yea my cop friend investigated it turns out after doing a full investigation the young man was running about 80 in a 45 zone and somehow during the accident I guess his case of beer came open but luckily he was able to catch most of it with his mouth so it didnt spill but unfortunately he was behind the wheel as the car rolled so technically my friend had to arrest him for DUI as he was 3 times intoxicated. No it wasnt fair but tne law is the law s my friend explained to him. Insurance he don't have to worry about that as he did not have any .Im staying home cars rolling over,guns blowin up its close to Halloween that crazy Jason character jumping out of the water getting people you can't even fish .Im going back to bed .Im apologize in advance not making light of your terrible situation but sometimes I need to laugh to keep from crying so I apologize sincerely for any offense before you are offended .The guy in the accident why was he speeding ? Oh my friend asked him about that also seriously he did .He told my friend he was in a hurry to get to the insurance company before it closed .Yea he had to charge him with because as he explained the law is the law .

The only thing that's changed is information availability. The internet hasn't made the world more dangerous, it's just made access to what happens more available.

Today we have less crime, better product quality and more educated people, but it doesn't seem that way. Why? Because things like youtube promote the stupid and broken. In the past, someone would blow up their gun and only the hospital would know about it. Now, it's posted on facebook and 100,000 people that never would have known about it, see it within 10 minutes of it happening.
 
I that happen with a Colt Delta Elite 10MM; no one could give me an answer, but did not go into full battery I think.. When I shoot any thing I pull all the way back on the slide and let it go. Also, the barrel lock up lugs had worn edges that could have been the real problem. S & W will take good care of you.
 
I might add

The Colt I was referring to had very many rounds shot through it; countless. The previous owner was a gun nut and reloaded his own ammo. I think the high power and use was the culprit.
 
Sooooooo.....................

Was there ever a determination/resolution to this?

I tried to re-read the thread but started losing my concentration.



I din't recall the OP ever coming back after the first couple pages. I believe it was determined the IP just wanted to vent and possibly trash the brand. If he ever sent the firearm in, he never told us the result.

This sort of thing has happened to me twice, though not with an AR. First time was an FN 49 8mm that had gas issues[over gassed], ripped the base of the cartridge off before the pressure had released. nearly blew my eardrums out but did not damage the rifle. Fixed it by installing a new barrel with a normal gas port.
The other one was a new AK with headspace problems, blew the magazine apart and I was slightly wounded. The distributor/manufacturer replaced it with a new rifle. It is an ATI milled receiver and the new one has been great.
I have had plenty of failures to go into battery with AR's [and my funky handloads] but the hammer would never fall on them, just jam up the rifle. I have since refined my case prep habits. It's also possible that a stuck firing pin could cause a premature discharge in a brand new gun. Still very unusual.

That's a fault I'd not heard of with the FN-49. Mostly the firing pin breaks and jams forward on the early ones creating a very exciting 10 round full auto burst.

The other issue is using ammo with too slow a burn rate. Despite the adjustable gas system, the FN-49 can go bad on you with Turk surplus and certain PPU ammo. Even with the gas vent full open there is still too much pressure for too long in the gun. The FAL works the same way.
