Hey /k/, im on the newer side of firearms. So I bought a AR-15 from a family friend about a year ago, 700 bucks came with 700 rounds of 5.56. Took it to the range this weekend and I would chamber a round, 1st round would fire right off dead accurate. 2nd Trigger pull the gun would not fire, extracted the round and it looked like it had struck but no bang. Well I put the magazine back in and tried again same thing. 1st round fire, 2nd no go. Tried 3 times then packed it up. Any ideas whats wrong and what I could do to fix it? Range Officer said that it was over oiled but I was skeptical.
Check to make sure the trigger and hammer springs are installed correctly.

Hammer might be striking light, or you're shooting Tula, and you're literally just an average consumer of Tula ammo.
>>28257931
>and you're literally just an average consumer of Tula ammo.
What? What does that even mean?
>muh literally
Christ people born in the 90's suck.
>>28257914
Not sure how to go about doing that, could you tell if I took a picture?
>>28257931
I was shooting American Eagle
>>28257931
Not OP but I've shot about 3k rounds of Tula through my ar without issue yet I bought some good 69gr soft point ammo that always gets jammed in the chamber
>>28257950
See the blue spring? It's backwards. It can cause light strikes. Make sure your hammer spring is NOT oriented this way.
>>28257931
Is that really the norm for Tula? I haven't had many problems in my PSA, though I dislike shooting it knowing its raping my barrel.
>>28257962
Maybe you posted the wrong pic.
That hammer spring is installed correctly.
>>28257962
This is how the hammer spring should be inside your lower receiver. Note how it is positioned against the hammer, in the opposite orientation of the blue spring of the other picture.
>>28257976
Just checked my AR...fuck you're right. Everything I said is opposite lol.
blue spring=correct orientation
>>28257940
Pump your brakes cum guzzler.
I was born in the early 80's.
Now go retreat to your safe space, you millennial chucklefuck.
Op here
>>28257990
The trigger spring is upside down in the blue spring pic.
>>28257991
Then explain what that sentence even meant? Who is the "average" tula purchaser? What is "literal" about it? As opposed to figuratively? Or metaphorically? What the fuck nigger get an education.
>>28257965
Depends on the setup. I've had ammo fail to fire because of a faulty primer more than a handful of times with Tula. I've had cartridges with no rim on it, just completely smooth. And I've had rounds fire and then fail to eject so badly that the only way to get the casing out is with a brass rod down the barrel and tapping it til it comes loose.
Tula is complete shit ammo. A good barrel, bcg, and a strong hammer will be able to handle it though.
>>28257998
You literally need to chill out with you asperbergers.
Don't get all hyped up and start rage punching holes in the walls.
>get an education
Coming from the buttblasted neet arguing over the usage of "literally" in a sentence. What do you make annually? Fuck that don't tell me. You take my annual tax liability and it's still more than what you see.
>>28257903
Was this a self build AR or a store-bought new?
If he built it, the hammer spring could be in backwards and cause that.
Other than that the rifle was shot a bunch and you need to do some maintenance on the BCG and replace the firing pin
>>28258031
I bought it second hand from a family friend. He bought it new from a pawn shop. No telling if they built it there or what.
>>28257998
>not knowing how light-loaded tulashit is
lurk moar m8
>>28258021
Not that guy, but you literally sound like a total faggot right now.
>>28258047
Check the spring according to the pics posted in the thread. If not that, then its a shot out BCG that needs a new firing pin and rings
I remember when I first got an AR the dents in the primers from the bolt closing freaked me out.
Like I was seriously concerned the gun might fire from going into battery due to the floating firing pin.
What I mean is, you say it looks like the primer was struck but the primer is struck when it goes into battery.
Not sure if that's in any way helpful.
>>28258102
Thats possible, come to think of it on the second shot the trigger didn't quite feel right.
>>28257993
That hammer spring should be flipped around so the legs are coming off the top, not the bottom. Quick, easy fix, just punch out the pin, flip it around to face the right way and put the pin back through the hole
>>28257993
Here's a picture of how it should be
>>28258062
Lurk more? I've had no problems with tula besides mediocre accuracy. Build a better AR or get an AK that isn't a century/IO/waffenworks. If you're using tula in your pistol then I dunno what to say, brass is barely any more expensive.
>>28258138
huh, mine looks right ?
>>28258187
>century/waffen

You know looking back now it almost felt like the hammer never came back down after the first shot. I didn't look because I'm new and still learning I guess.
>>28258187
Tula has failed to cycle my PTR, both my ARs, and my buddy's Saiga. Definitely not a weapon problem. Plus it's no cheaper than some much better brass ammo.
Alright, the lower was probably assembled properly, did you save the struck but non-fired cartridges? What do the primers look like?
Is it possible there is something wrong with the BCG? have you completely disassembled it and oiled it properly yourself?
As far as the range officer suggesting it may be over-oiled, he probably has his head up his ass. 99% of AR's on the market work better "soaking wet" with oil. They simply work better with too much oil than with not enough oil.
>>28258256
If that is the case then the disconnector is not functioning properly. The disconnector or disconnector spring is modified or installed incorrectly.
The fire control group could be a really shitty one, or there may even be a problem with the hammer but thats not likely.
>>28258391
I threw them in the misfire bin, they had a dimple dead center but not as hard as the 3 rounds that I actually managed to get off.
>These people getting pissed off about Tulammo
>mfw my S&W M&Cheap fires Tulammo fine
>>28258429
yeah, thats something you should do. Its throwing away data about your gun.
So the thing with steel cased ammo is steel is less flexible and malleable than brass. Because of its metallurgical properties, it doesn't expand to fill and seal the chamber as well. This results in under-gassing of the system which can result in a slow cycling of the bolt. Simply put, think of it like a super weak round sometimes when the stars align which is a low powder charge, poor chamber seal, and a non-broken in gun.
AR's ordinarily produce a small dimple in a firing pin in an ordinary closing of the bolt. You can even try this now: lock the bolt back, put 1 round in a magazine, and release the bolt, then eject the live round. You'll see the primer has a small indent on it from the primer. This is normal because the firing pin is free-floating, I wouldn't recommend doing this multiple times, and do use common sense and gun safety when doing this.
Also, because of the poor sealing of the chamber, additional chamber fouling will be produced and unburnt powder can cake in there. This can sometimes prevent the bolt from completely locking.
Next time, fire a round and if the 2nd just goes click, look at the bolt and see if it is completely locked and seated in the firing position. Tap your forward assist to see if it moves forward into firing position.
tl;dr steel case ammo doesn't always work well with guns designed for brass case ammo. See if you can reproduce your problem with brass.
>>28258670
Shouldn't do.
I bought a shitload of herter's steel case ammo thinking cheap ammo would be more funner. It just produced problems, and many ranges don't allow it.
>>28258187
You realize this is scientifically testable right? Tula is lightly loaded by a significant margin, and steel cased untapered cartridges are dumb anyway.
>>28258670
Actually I was shooting brass cased American Eagle
>>28258754
My mistake, from all the tula talk i assumed you were shooting steel case.
Then you need to check your chamber, throat, and bolt. What buffer and spring are you using?
>>28257979
I had this problem with a trigger I put in myself. There's a tiny spring under the disconnector if that's not there it will cause one good hammer fall and a light hammer fall with a soft primer strike. Check the spring under the disconnector
>>28258138
His looks correct
>>28258200
I'm telling you bro check the spring under the disconnector
>>28258819
the forks on the disconnector or are facing torwards the magazine, the spring forks on the hammer are facing the stock.
>>28258797
I counldn't tell you man, I bought it used second hand.
>>28258883
thats not the disconnector
the disconnectors the flat piece of metal in the trigger and its possible for the spring under it to be installed upside down
the wide side should be on the bottom
>>28258893
I assume since you bought it, it is within your possession. Go break it open and fucking look.
>>28258939
if his shits generic the buffer wont be marked
neither would the bufferspring
part marked in blue is disconnector
red arrow is pointing at spring
Fuck Florida and fuck alligators.
>>28258939
yeah there was nothing on it.
Jesus Christ, autists...just look the shit up on Jewtube.
>50 f'ing posts trying to figure out which way is up
Get on with it:

It'll be okay
>>28259091
wow okay, this actually really helped.
Can't take it in the back yard and test it, live in a very populated area. Thanks guys.
