You get what you pay for...PSA issue

[shooter556]

So I took my brand new PSA dissipator build to the range this week.

Shot around 50 rounds of some brass CBC M193, all good no issues.

20 rounds of PMC xtac 5.56, all good no issues.

The main issue was when I tried shooting some Wolf steel cased ammo through it. It would fire the round but it would not extract. I only fired three rounds, first round fired and extracted, and after the second round, it seemed like the extractor chewed at the steel casing. So I separated the upper from the lower, and extracted the steel casing with a cleaning rod. Chambered a new round, and again, did the same thing and did not extract.

I'm not disappointed, because it was cheap. So you get what you pay for. I've heard PSA is a hit or miss, sometimes you're lucky and stuff works right out of the box. Other times you need to replace things.

Looks like I might need to replace the extractor. Although I inspect it and don't see any issues with it. Just dirty. Any issues replacing it with any other standard mil spec extractor?

Do you have another BCG to try before you order parts? How hard was it to remove that stuck case with the rod?

I'd thoroughly clean and lube the chamber and retry with a box of brass cased which will probably run fine. Relube for the steel test and see what happens.

How's the timing? I bet that thing is way overgassed.

FA bolt carrier or standard?

A nice chamber polish never hurt anything.

Extractor is not the problem, looks like it held on for dear life.

Did you clean the chamber well before hitting the range, got all the preservative out of it?

ive seen certain 16 inchers that just cant handle wolf within 5 cases the chamber gets too dirty and cases wont eject

i think i have a couple myself

wolf runs fine in my 20 incher and my mini 14 but its just so much gunge bulds up on the wall of the chamber they wont eject

i really dont know why other than maybe the steel case doesnt seal up around the neck as good as it should possibly underpowered maybe its the wylde chamber

BCM says not to use crap ammo like wolf. Because, guess what.... You'll get crap results!

Isn't trash quality ammo typically way low pressure? I've always heard that most cycling issues with steelcase was that the gun needed more gas in order to cycle with the weakass ammo

I'll admit I'm not a gunsmith and def not a gasport scientist or expert.

Its probably the steel cases, not the gun. Clean the chamber really really good before and after you shoot steel cased ammo.

I think steel cases tend to bulge as well.

OP, can you post up a picture of the upper when you can. I'd sure appreciate it.

I like a few of the comments. A dirty chamber will sure do that damage along with being over gassed...that's been my mediocre experience

I don't run steel case ammo at all---hard on gun---brass cased ammo always...

Here's the upper. Just a standard PSA dissipator

I have an LMT 16" with hundreds of steel cased through it and not once has it got stuck.

I will try to clean it and do another test with another box of Wolf ammo. I only had brought one.

This is just my budget build and more for the "retro" look anyways, if it doesn't like steel it's no issue. I will just not use steel ammo through it but it would be nice to see if I can get it to run.

My 16" PSA mid-length does the same thing with steel case but my mini 14 eats everything, so it might be the upper chamber.

I get the same thing happening with wolf on my scar 16. It rips the rim off every few rounds. I stopped using wolf and just stick with brass case with no issues.
