I have a new 2TL that I have only gotten to take out and shoot twice now. The first time I got to put about 6 rounds of Wolf through it and one was stuck in the chamber. I didnt have anything to poke down through the barrel so my range day was done.

I racked that up to the Wolf and bought some Remington UMC 55gr. I fired 30 rounds yesterday and everything was fine. I reloaded. ( I only have 1 mag right now) and the next 70 rounds I had to all manually cycle into the chamber because it wasnt feeding the next round in.  So would this most likely be a Mag problem?

Im about to go check the warranty info on the stag website. Any info would be appreciated.

Thanks

Yes, it does sound like a mag problem - are you sure it was seated firmly?  Is this the mag that came with the rifle or what?

Try another mag.  A mag like Brownells sells for example - $14.

If you continue to experience probs then for sure contact Stag, I'm sure they'll help you out.

It could be a number of things, but Stag does not do a great job of staking their gas key on the bolt carrier. This could be the issue as well.

Yeah, It was the mag that came with it. Im gonna buy some more. I have just been busy and havent even hardly had time to go shoot anything here lately. It was seated. Thats the first thing I thought of. :)

Thanks for the replies. I can piddle around and fix most anything that goes wrong with any of my handguns. Im pretty lost with this AR though so I was bummed when it was having probs. If it where a handgun I would be about 99% sure that the failures caused by my last shooting trip with it where Mag related but like I said I dont know much about this rifle.

Yep.  

Try this, load one round only into your mag, and make sure your BCG is well lubed.  If the bolt won't stay back on last shot, check your gas key/bcg.   If it stays back, try loading more rounds and see how it goes.  New rifle may need a little extra lube until you get a couple hundred rounds through it.

I'd check the Industry forum *( tab @ top of this page ). A rep. from Stag canb surely help you there. Post your problem and they will get back to you

ARs need to be well lubed period..not enough lube+a new mag+new stiff and tight rifle will give problems...lube well try s different mag and see.The rifle is gonna be real tight until you rin a few thousand rounds through it.

This is not bad advice, but it also not necessarily true. New gun does not automatically equate to a tight gun.

i had a upper short stroking, i tried many different mags and ammo types, called stag and my upper is on the way back for an exchange, e-mail them, super fast and friendly service, even e-mailed me a pre-paid ups label to send it back. i will buy stag again because of their excellent service

I just fired my new lefty Stag 15L for the first time. The rifle never cycled. I had to manually pull back the charging handle each time I fired the gun.

The range officer suggested I lube the new gun really good.

I went home and did a thorough cleaning and lubing.

You think this will help my problem?

This is the first time ever owning an AR15.

Its possible, but never cycling at all sounds like more of a gas pressure issue than anything else. I'd check to see if the gas key is staked correctly and the gas tube is installed proper.

A new gun, which isn't dirty, should run for a little bit even if it were bone dry.

Someone should post the "How an AR works" graphic for these guys so they can detail exactly where in the firing process the failures occur. Descriptions over the net make deciphering what they are trying to say difficult.

ford1911; I can imagine your failure with Wolf is a result of a dirty chamber, they test fire guns with decent ammo and you used steel cased stuff that tends to be sticky. The sceond failure "sounds" like you simply did not seat the mag properly as it worked immediately before hand. I suggest you clean your rifle (chamber), generously lube it until it gets broken in, and firmly seat mags.

chavezding: Did your rifle cycle partially or not at all? If it didnt cycle at all you likely have a gas leak. This could be caused by a number of things on a new rifle, among them the lack of a gas port being drilled, mis aligned FSB, carrier key being loose, etc....

A guy at the range had his carbine start going single shot a few weeks ago.  

He did the empy mag test and found that it wasn't cycling at all.

He pulled the BCG to check the gas key.  That wasn't the problem.

Looked at the gas tube, and it was floating back and forth.  The gas tube retaining pin had come out.  He put a new pin in later in the week and came back to the range and was in business.

Moral of the story: If it is gas related make sure you check the whole gas system.

Does Stag test fire one round before putting it in a box to ship?

Seems to me if they do test fire, then someone missed this big time (But the shell would still be chambered) or it just didn't get fired at all....

I had the FSB issue on my Stag upper. The replacement I got had a nicely staked key. Maybe the new runs are gettting the proper stake job and maybe I got lucky....

I bought a Stag Arms 2H Upper earlier this year to go on the Stag lower I had assembled.  Initially, I did have some issues with the bolt missing a round, and then an ejected round would get hung up in the ejection port - all wolf steel cased, BTW.  After a complete cleaning and application of CLP, and some good brass ammo, everything works fine now.  Have probably 500-600 rounds through it.  My C-Products mags needed a few rough edges smoothed out, too.  Maybe your upper does have a more serious gas system issue.  I'm sure Stag will do the right thing.

It didn't cycle at all. I shot about 70 rounds that way, manually pulling the charging handle each time.

I hate to sound like a total NOOB, what is FSB?

How can I tell if the carrier key is loose?

What does a properly staked key looks like?

HELP!!!

just an update.

I emailed Stag and told them what was going on and asked if they had any suggestions. He said from my description it sounded like it may be short stroking. They are going to send me a pre paid label to ship it to them so they can look at it.


On a side note....I should probably take the EOtech, the surefire and the forward grip off eh? The scope and falshlight arent a big deal but that Tango Down   eeeshhh

How can I tell if the carrier key is loose?   It will move on top of the bolt carrier or you may find evidence of gas leaking around the base of the carrier key.

What does a properly staked key looks like?   There should be punch marks near the carrier key bolt heads that forces some of the surrounding metal against the bolt heads.  HELP!!!
