PSA upper opinion, is this a problem or not?

[BigShep85]

Ok, I recieved my upper and this what I found. I had a couple rounds the other day hang up but just a couple out of 100 or so. So I took it apart at home and this is what I saw. I picked up some emery paper for polishing just to see if that would help but the feed ramp seems to be misaligned. Is that just the perfectionist in me or could this be the problem. Would you consider it a problem or am I over reacting?
Does anybody else's' feed ramps look like this and have no problems?

 

[HOOfan_1]

It looks like they might have installed a barrel with a rifle extension in a receiver with M4 cuts...that is not good

or it could just not be aligned. Take a round and rub the tip of the bullet up the feed ramp on the receiver and up the barrel extension and see if there is a catch in it.

Wow, nice example pic HOO. It's kind of scaring me though, this is the second questionable PSA thread in as many weeks and I have one that should be shipping any day now. At least I'm learning to check it over really good when I get it.

 

[Walkalong]

They do not line up well, that's for sure. It isn't as bad as a rifle extension with M4 cuts in the upper, but it's not good.

You can either fix the barrel extension so they do, if you are comfortable with that, or call PSA and return it for repair or replacement.

 

[Hacker15E]

I would get in contact with PSA customer service and show them the pic, and see what they say.

FWIW my black friday PSA upper (m4 carbine premium flavor) came a couple days ago and the feedramps are fine. I'm not an ar expert so I haven't totally stripped it down, but as far as I can tell it's fine. Gas key staking is a little weak.......

 

[BigShep85]

Update

I broke it down again and cycled some rounds through it. It seems that the rounds were getting stuck between the.....not sure what it is called....little opening right above the feed ramp. That can be fixed with a little polishing I think. Seems to me that the edges are too sharp and can use some polishing a little.

It's definitely a problem, but as I've recently experienced, it is the opinion of the membership here that this is to be expected *and* accepted at this price point. They might ask if you've contacted PSA for an RMA, and you might even be asked to post your order information.

I hate to be the first to tell you, but you bought an upper based on the posted specifications and recommendations of others, then got burnt. Ultimately, you'll be blamed for any disdain for what you've been delivered.

In this day and age, there is no free lunch with AR15s. When you come across a bargain, you've most likely just purchased a parts kit of sorts.

boricua9mm, grow up. "the opinion of the membership here" is that you should be certain of what you are ordering before you do so, and if what you receive isn't what you ordered, you should contact the company to give them the opportunity to remedy the situation before crying about it on a forum. you flat out refused to contact psa about your issues and went on with your temper tantrum anyway.

op, as walkalong stated, you can right this yourself if you are capable, or contact psa and talk with them about it.

let us know how it works out.

That feed ramp "misalignment" most likely isn't a problem but see what PSA says about your picture. Over the years I've seen pictures of M4 feed ramps similar to or worse than yours and almost always no one liked what they got but reliability was good. (Dozens of brands were involved, not just PSA.) Now if the bullet tip is catching on the barrel extension then that's definitely a problem.

The 2 "hang ups" out of 100 ... what exactly happened? Anything come to mind what actually happened? Same magazine? Same ammo?

Oh please. You refused to contact psa or to send your supposedly wrong bcg back for replacement, were rightfully asked to provide information in that thread about your purchase to see if you were indeed sent the wrong bcg, and instead of providing that information you got all defensive, the thread was locked, and now here you are overdramatizing like crazy again.

OP, I agree, that is something that I'd bring to psa's attention. They do seem to be having some issues with builds lately.

 

[Jackal]

Feed ramps are indeed not aligned. You could contact PSA or lube it up and run it in. If it were me and the rifle still malfunctioned after about 200rds, I would contact them for a fix. I'm a big fan of PSA's high quality to cost ratio, but it seems PSA's holiday crunch quality control kind of goes out the window...:banghead: I have a MOE complete lower on the way, hope its ok.

 

[BullSlinger]

From what I can see in the pic. It looks fine to me. I am no expert but I have been shooting M-16 AR-15 since 1972. Just my 2 cents.

 

[MistWolf]

I had the very same problem with my PSA upper equipped with a 16" stainless steel barrel and I also had feed jams. I contacted PSA, explained my problem and they sent me a shipping label to send it back. PSA cut the ramps correctly and sent it back. I think it all took two weeks or less. They called me on the phone to see if the work had fixed the problem. It did. Not a single bobble since.

Dealing with PSA customer service left me with the feeling I was a friend as well as a customer and that they were just as interested as I was in solving the issue

Mist, looks like they ended up milling some material on your barrel extension. Maybe the extensions are out of spec instead of being installed incorrectly.

 

[MistWolf]

Yes, it was the barrel extension that didn't match. The barrel was made for PSA by Wilson if I recall right. I think the barrel extension had rifle ramps. In any case, I was happy they matched the barrel to the lower without touching the anodizing

 

[gunnutery]

I'm new to ARs so please correct me if I'm wrong, but it looks as though it's correctable with just a small round file. Even if that was the right way, I'm still not sure I'd do it myself, but I wouldn't want to wait longer again either.

 

[Davek1977]

If you don't give a company at least a CHANCE of making things right, you have no room to badmouth them, IMO. If you find an obvkious screw up, and the company refuses to work with you, thats one thing, and I can see ranting on the forums about such an experience. However, having read Boricua's thread....that simply isn't what happened. He just didn't like the "words of wisdom" the membership gave him, from what I can tell....

 

[Warp]

Do you know they could make things right?

Stop shipping out defective crap.

I think we have more incidents of this kind of thing with PSA than we do with every other AR manufacturer combined. It's almost like one of these threads goes up every other day. And it's been like that for a long time, hasn't it?

The consumer shouldn't be the one doing QC inspections.

 

[MistWolf]

I'm not sure how hard the barrel extension steel is so I don't know if a file would cut it. In this situation, it's best to let the manufacture fix the problem. If you attempt to cut the ramps on your own and you screw it up, replacing the barrel is on you

Colt sends out clunkers too. PSA is probably selling more AR parts than everyone else combined. Little wonder they come up often.


OP, you don't want any edges that could catch a bullet tip. Call PSA.

 

[BigShep85]

I have emailed PSA, i will see what happens from here

 

[M1key]

I have had these problems with two lower-end builds and successfully fixed them myself. They both look like the picture of the finished PSA extension Mistwolf posted.

But, I agree if you aren't comfortable doing it yourself, send it back.

Good luck

[Ditch-Tiger]

PSA will make it right.

I agree that it isn't perfect but its not horrible.
May I ask what type of bullet (sp, fmj, hp, etc) and mag?
I have found that P-mags sit a tiny bit higher in the magwell and may solve the issue . (I had an M4 upper w/ rifle extention and every time I shot SP's or usgi mags I would get stoppages and this fixed my issues)
But, since its a new gun, send it back and have them fix it. You shouldn't have to trouble shoot a new gun.

 

[Fishbed77]

I wouldn't be that surprised to find out they shipping out more rifles than any other AR manufacturer (maybe not combined).

You read LOTS of internet reports of problems with Glock pistols too. There are just a lot more of them out there.
