First jam on the new Sport II

[Lee's Landing Billy]

Semi-auto's occasionally jamb....ammo , magazine dirty action.....
Just a fact of life . Don't let it bother you...un-jamb and Carry On.

May be the first but it won't be the last !

Thank you X 100!!!! It's what they do. If somebody tells you they have NEVER had a stoppage in a semi of any kind, they are doing a lot more carrying and rubbing it than they are shooting it. Today there will be a dozen men here shooting thousands of rounds, when somebody has a stoppage we all shout..Don't be mad, that's what they do!!! Clear it and SHOOT!

Nope! This thing isn't leaving my sight if I can help it.

Never did post a picture so here's one I took while out today. Lots of tonnage to carry around.

Is there an ATM somewhere on that rifle?
Seriously, you've got it going on there!

I have never had that problem either Pmags or brass cased ammo. I had a Bear steel case round that was jammed so tight the range officer had to take a rubber mallet hitting my charging handle to free. That was with an older generation M&P MOE. He knew exactly what to do and said is pretty common with a Russian ammo. I know this is a little off subject, but I have to think most causes of AR jams are either ammo or dirty chamber related.
I assume it was the cheap Russian steel case ammo so I gave what I had away and bought a BCM charging handle in case the original was bent. Just as a precaution, you might want make sure your charging handle is not bent.

There is NOTHING wrong with Russian ammo. Me and my gun shooting buddies use it (Wolf & TulAmmo) about 95% of the time. We buy it by the 1K round cases from SGAmmo.com
A bit of advice; by this Extractor Upgrade Kit from BCM and you can shoot Russian ammo to your hearts content!

A week ago, I traded into yet another LNIB Sport II (I loves me some wheelin'-n-dealin' on the Armslist! ), and took it right out to my secret range nearby for a quick test fire. In the first couple rounds I had the exact same issue the OP had: a round jammed in tight, and wouldn't seat or extract. I finally pulled it loose (just tugging on the charging handle).
The round was bent and looked just like the one in the OP's pic.
I had a feeling my magazine wasn't fully inserted (I didn't think to check before removing it to deal with the jam).
After that, the rifle ran flawlessly, and did so for the next 3 consecutive days.
The last day I was out there (day before yesterday),while using my motorcycle seat as a rest, the seat rubbed against the magazine and pulled it out a little. I gave it a slap, and checked it, and it still didn't seat, so I popped it good, and it locked in. This was a P-mag, same as I used when I had the glitch, so I'm pretty sure it was just an improperly seated mag, and wouldn't be surprised of that's what happened to the OP, as well.

Zero jams on my COLT LE 6940.

...the seat rubbed against the magazine and pulled it out a little.

Did you mean the seat hit the mag release? I don't see how a properly seated mag could be "rubbed" and come out a little.

You probably just look at it and admire it more than you shoot it.

Do you think Colt has never had a rifle that had issues?

He is saying that the magazine wasn't properly seated to begin with. He had to smack it with some authority to get it to lock in.

I have personally cleared hundreds of jams on Colts in the two years I was a Drill Sergeant at FT Benning Ga., just saying.....

I don't understand the critical remarks directed toward those who have not experienced AR jams. Aren't these guns and magazines designed not to jam with a variety of ammunition? A reasonable person would assume that's the case. I suppose everyone should be prepared for a malfunction, but if it doesn't occur, that's okay.

It's not towards someone who hasn't experienced a jam... It's towards the Colt fan boy who always posts about his Colt in the S&W forum, implying that the S&W is inferior.
