Hi there. New guy here. Just purchased an entry level PSA AR15. Went to the range and kept getting a jam. Rifle would not load a cartridge properly. I thought I would post a pic of the ammo that was scarred to see if anyone could give me a hint of my problem. Totally new to ARs. Using basic brown box Winchester ammo.
Thanks much!
Pictures would help, specifically the action area of the rifle.
What did you do to it prior to the range trip?
did you clean and oil your rifle? and, how old are those cartridges? They look mighty tarnished.
So many factors. What magazine were you using? Did you clean and lube the chamber?
All PSA firearms are test fired so we know it works, now just have to troubleshoot yours.
Yeah the ammo looks a little rough. Are those new rounds or remanufactured, what magazine are you running? Make sure you are running the AR wet, lubed that is.
Could be a dozen things going on. Pictures will definitely help us try and help you out 
Seen bad mags do that to ammo in otherwise perfectly fine rifles. That’s where I’d look first.
I Second Don. Look to your Magazine, THEN to the firearm
Pretty much all Winchester ammo I’ve bought in the last three months has been blemished like that (5.56, .308, and 7.62 Nato) but I haven’t had any feeding issues with them. I think Ukraine is getting all the shiny brass from the government ammo plants, that’s all. I agree the magazine would be the probable culprit.
Thanks so much for all the responses. The rifle was pretty dry internally after purchase. I did a simple breakdown (not too far). I cleaned the barrel with hoppes solvent and did a lot of wiping on the moving parts. I cleaned off a lot of black soot. I did very simply lubing on moving parts and a light wipe on the other areas that I thought would see movement/friction. I am using magpul gen 2 plastic mags. The jams happened consistently with three identical mags. All mages were loaded to capacity. The ammo is a month old (to me) from a PSA retail store. I will get pics of the rifle as soon as possible. I know this is hard to decipher via the forum…but I thought I would lean on any patterns you more experienced shooters have seen. Thanks again.
It sounds like you wiped it down pretty good. Any lubricant from coming out of the box is minimal. I think you need to lube her up really good IMO
Thanks for the input. I guess I should be systematic about this…
I will lube her up real good and try my ammo. After that, my next step will be to pickup some higher end ammo and try that.
Any recommendations on lube type and brand?
SDI. Their homemade is good. Synthetic grease mixed with 5W whatever synthetic motor oil.
a couple months ago I pulled one of my ARs from the cabinet and took it to the range since it hadn’t seen daylight for way too long. I didn’t realize how dry it was since the oil had all settled out. It jammed up on every shot or 2. I didn’t have any gun oil with me and there wasn’t anyone there that had any either. Then I remembered I had a new quart of oil in the back of the truck and lubed up my bolt some with it. Ran like a top after that. They like to run wet.
added a link to a good diy gun lube.
That’s the one I was thinking of! Thought it was SDI, oops.
Some ARs like to be REALLY wet. Lube it up and break it in.
I like Hoppe’s 9 products myself, probably because that’s what my dad used.
There are lots of lubes between oil and grease.
Mobile 1 motor oil and CLP or just whatever you have available. Just use plenty of it to help it run smooth
I messed up and dumped actual Sriracha in my BCG last week. I still can’t see out of one eye, but my sinuses are clearer than ever in my life.
See that happened to me the other day except it was with Skoal. Now my BCG only functions with a shot of tobacco juice to the face. I think Copenhagen and Red Man would do the trick as well 
Yikes!
