The 5th round from the right reminds me of one of the pieces of brass from the Colt kaboom thread that everyone said was run over by a lawnmower. No it doesn't. For one, the round in the Colt thread had chewed up irregular looking edges. Two, the round in the other thread was already fired, and that damage could not have occurred before it was fired, because it either would not have chambered with that degree of deformation, or even if it was able to chamber, the pressures of the firing and the bullet leaving the case would have straightened it to a large degree. Whatever chewed it up, had to have happened AFTER it was fired. That is not to say the rifle didn't do it, but it simply can't happen the way you are warping it in your mind. |

I think that nobody would disagree that a picture of a handful of cartridges with the bullets pushed in is not good advertising for PSA. Anyone that uses their head would not assume it is a PSA problem. The problem could be caused by the ammo, the magazines, or the rifle. I have seen more than a few "improperly aligned" feed ramps, including on my Colts, and they do not cause any problems. The right feed jam is usually caused by the mags. Although PSA has even come on here and stated that the round should be hitting towards the center of the feed ramp, the small misalignment in the pictures, once it is realigned, is not going to cause the bullet to hit center, based on how far off to the left the rounds are currently hitting. The rounds may very well have too little neck tension or improper size bullets, so the rounds may be doing what most other rounds do, but instead of bouncing up into the chamber, the bullets may be setting back some, which is causing the brass to catch, which in turn causes the bolt to drive the bullets as far back as they will go until the powder stops it. |

I have Colt,CMMG and Bushmaster M4 and SOCOM barrels the ramps on the extension match up perfectly to THM.CMY and BCM M4 marked uppers.While there should be no lip where the extension ramp meets the upper ramp and on Colt barrels the upper parts of the extension ramps are always polished..extension ramps to upper ramps are seamless smoothe.If the cartridge is hitting the ramp itself then its a mag problem or magazine spring problem and then if theres a rough ramp problem all of those together can make feeding problems.Look at how rounds feed in a non M4 ramped upper its the cartiredge shoulder that hits the ramp as the round pops up and angles up.Send the upper back and let them deal with the product they built,send the pics and describe the problem..glad you werent hurt.Then when it comes back try different ammo and mags along with your original mag and ammo combo and see.

There is no other reason for you to have made that statement. It has nothing to do with anything that was happening in this thread or in the other one. |

to get back on topic, I got my UA back from PSA today. They replaced the upper but not the barrel. I haven't had a change to shoot it but will in the next couple of days.
Here's a picture of the new ramps. The barrel ramps look more symmetrical than they did earlier. http://img525.imageshack.us/img525/3778/20120629230142.jpg |

You can tell from the brass marks on the ramps it was fired..the bottom line is not necesarily the upper had a problem..but more how the company resolved it and they agreed to take care of it and that means alot.Now to test fire it yourself and see.Alo try a few different mags and a few different types of ammo to see how it runs.

I have ammo from three different makers and some Pmag mags now, so we'll see how it goes on the range. |

OK, just got back from the range, with the following results:
I fired Federal 193, PMC and Brown Bear 62g HP. I tried them in Pmag and Tapco mags. All three ammos loaded perfectly from the Pmags, but as soon as I tried them in the Tapco mags, the gun jammed again and again on the right ramp. So, all of you who blamed the mags are at least half right.
The rifle now shoots like a dream. tight groups at 33 yards with all ammo types. |

They should have polished up the feed ramps a bit so they are at least even. The barrel extension ramps still look a tad smaller, which I would think COULD case a problem, but if it works to your satisfaction, probably no need to mess with things. |

Those ramps look as good or better than most I've seen. They look as centered as you could get them. Shouldn't require any polishing. Now that everything is fixed just stay away from junk mags and should be gtg.

Shitty mags, shitty ammo, equal shitty results. Destroy those tapco mags so you dont pass the problem to anyone else.
