Had a FTF with my AR15

[lovemachine]

I was having a little range day with my brothers yesterday. And we were shooting my RRA AR15. The very first time I shot it, I had a FTF. I performed the TAP/RACK/BANG! method. Nothing, and I noticed the cartridge never ejected. So I ejected the mag, racked the charging handle again. And I had 2 cartridges fly out.

I picked them up, and one was good. The other, well, not so good. It was a factory Rem. that I bought from Wal-Mart. And the crimping on it was just horrible. The bullet was in the casing, but it was way inside, with powder just pouring out, when I turned it upside down.
I took some pictures.

That sucks.

I've had that problem with a .45acp round once. It was a carry round so after being chambered repeatedly the bullet started to get shoved into the casing.


Bad rounds make it through, I was with a friend shooting his AR and somehow a .222 got into a bunch of .223 ammo. The bolt assembly failed to grab the round, it just jammed the round in.

You shoot enough and a bad round or two is just a given


Sweet rifle by the way

Was this the only round that, or was this a re-occurring issue?

I've never seen a bullet set-back that far before. Wow.

I came across 2 9mm like this out of the umc line. Never bought it again. I just go with win white box now.

Did you have anymore miss feeds? Did the other round fire and the empty not eject?

That's why I always inspect every round I load in my mags. Takes longer to load but these things happen from time to time.

And this my friends is why I put a light crimp on my reloads...

Not knowing anything about this particular AR, could the feed ramps be incorrect?

See the "Bad" picture at the bottom left in the link. That condition could certainly cause a FTF.

If you have a lot of rounds through it I would think that is not the problem though.

if this was the only round to do that it no big deal but if repeated then there is a problem with the weapon.

That was the only round.

I shot 1,000 rounds flawlessly right after that first round.

I've never had any problems with this AR.

Interesting

Sounds like a FTE followed by a double feed. The second round was slammed into the back of the first round caused the bullet to smash into the casing.
