First jam on the new Sport II

hdrolling said:
So was this a double feed? Looking at the round it has the markings of another round hitting the middle of the round pictured.

I dealt with this a lot when I was a Drill Sergeant at Ft Benning for two years, thats just what the double fed round looked like.

I think you're spot on Sarge. Loaded five rounds of my hog killers and went through those like butter on a hot skillet. Pulled that mag out and inserted a freshly loaded mag. The second round jammed. :confused:

This time I just dropped the mag and ejected the round with a little effort. I unloaded the mag and examined every round carefully. Every round looked good to my old eyes so I loaded five rounds in the mag and tried again. Fired smooth as silk. Loaded up 10 rounds and that went without a hitch.

I was pretty confident at that point that the mags are just tight and the second round down may be sliding forward by friction. I was getting hungry so I loaded up the remaining 13 rounds and went "full semi-auto". :cool: Brass was flying everywhere! :D

What's the deal with the mags? Will they loosen up or do I need to do something to get 30-round use out of them? Or are they just junk?

If happens again Call S&W and they will send you a pre paid shipper to send it back and they will correct anything wrong with it.

The mags or the rifle?

I'll put a few hundred through it first. I'm not convinced there's anything wrong with the rifle just yet. I think the mag springs are too tight, stiff, strong, whatever.

Anyone treat ammo with dry lube? Would that help?

We never had time to mess with bad mags in the military and just marked them and didn't use the bad ones anymore.

You might have better luck with metal GI mags or stock up on the PMAGs when they have the 10 mags sales going on.

Others here might have better mag trouble shooting advice, hopefully that's what your issue is.

Good looking rifle you have there!
 
My friends had a jam a couple days ago when we went shooting. Put a little dent in the round, he fired it before we left however. He's put around 160 rounds through it in total. I haven't had a problem with mine "knock on wood". that was using wolf gold.

Every time I have had something like that, it has been an issue with the magazine.

I know the whole AR world is ga ga over P-Mags but I ditched mine for some blackened stainless steel mags from C Products and haven't had a single problem with them.
 
A lot of people go by the rule of always put two less rounds in the Mag.
28/30 18/20 etc....
Like mentioned above, I like the ASC metal mag's
And remember a Rifle is a mechanical device, S**T will happen....
And mosquitos in Texas, Who knew....
Enjoy your Rifle..

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!
 
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! :D), 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.

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.

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.
