Help with DPMS 22 LR upper

[msarazin]

Calling all dpms owners. I have a 22lr upper that all of a suuden is is having FTF issues. Every 2 or 3 round jams halfway into the barrel. It ran great for the first year I shot it, but this year it's a f**king #####!

I've cleaned the piss out of it, oiled it up, ran without oil. Tried every 22 ammo known to mankind, even dummy rounds FTF properly.

So, if you have had the same problem and solved it, please speak up. I would also appreciate a pick of the bolt face, bolt bottom and mag lips.

Thanks guys.

I've had one for 5 years now and it has run flawlessly. Now and then it needs a really good cleaning. The feed ramp needs a bit of a polishing as well. It doesn't have any nicks on it does it, the feed ramp I mean. The only other thing I would check is the magazines. Maybe the lips on the mag has been altered slightly and it doesn't release the bullet properly. You haven't dropped a magazine by chance? Does it do this with all of your mags.

The only issue I have ever had is FTF from light hammer strikes. Thats a result of using a match trigger on my AR and I had been warned that this might happen.

Sorry I can't be more help.

Something else just came to mind. Check out the rimfire section of AR15.COM and see if anyone has had similar experiences there.

BTW, if your interested, I have two 10 round mags for sale at $85 each.
