Hi
I was shooting some tin w my NEA AR15 last weekend.
After about ten shots the cases weren't extracting. I'd need to manually work the extract lever (correct lingo?) to extract. The cases would feel quite hard to pull out.
It would cycle ok for a couple more shots then jam up again
Am I doing something wrong??
I'm new to using my AR, be gentle please!
Thanks
Si
It is .223 cal, I'm using the h&f branded 55gr ammo
Make sure the gas key is securely attached to the bcg is it a factory rifle
What's your setup? Barrel length, suppressor? Does it lock back on an empty mag?
brass ammo or steel?
any marks, dents etc on extracted cases ?
Ammo is dirty but not damaged.
It has a suppressor fitted. I'll need to measure the barrel (duh I know)
The bolt was extracting then closing on last shot
Gas key attached???? Ooooh maybe I've missed something there? The gas key knob moves maybe a little but not sure what it should move like
The h&f stuff is brass, it's their recycled stuff I think.
I'm not sure if it's factory......
I'm suspecting I need to spend some time face to face with someone who knows these things better than I lol
It shouldn't move at allQuote:

That said @marky123 had an issue with his new NEA where the caps crew head broke.
Also give the chamber and bolt carrier Group a bloody good clean as they get quite dirty, especially with a suppressor attached.
Cheers

A bloody good clean is my first job yes
as above the gas key should be more rigid than a bishop at a boy scout convention. disassemble the rifle and look at the chamber. look for abrasions and "rough bits".
if its a new gun, take it back.
if its not, come back to here
SiB take heart as you are doing better than me by knowing what a gas key even is, unless it is the pokey outey bit on top of the slidey doodad.
The gas key is the part that's screwed onto the top of the bolt carrier group if its loose it won't be getting enough gas to operate properly the gas doesn't go where its supposed to go is it a new gun
So it is the pokey outey bit on top of the slidey doodad.Quote:

Most people know it by its common name of gas key. ;)

Ah yes but I'm not a common sort of a cuss Pete.Quote:

So is it a new gun or has it been played with
Just about its the pokey out thing with a hole in itQuote:

Though knowing how lose the OP is to Fjiordland, it could be one of the sandflies....
does it do it with the suppressor off ? .... supprsors can up the speed of the extraction , if the case is still in expansion then it wont be able to be extracted easily .... try a couple of mags with no suppresor .... and see , ...
Thanks guys
My AR has a similar problem although with mine not every cartridge slams home in the chamber & I can only extract it by holding the gun on it's butt then knocking the bolt back with my hunting knife handle as I hold the lock bolt open. If I want to extract a round @ any time manually after a hunt for example, it remains stuck in the chamber. I've cleaned the chamber heaps & always check my reloads with a chamber gauge so it'll be up to spec. I have seen though on a You tube vid that it's best to use a small base die set made for the AR (not standard 223 dies) & crimp the projectile could solve the problem, although paying $110.00 for a new set of dies isn't what I want. I may have to take it to a Gunsmith. I also bought this early last year off "AR15" on trademe & it's been like this from day one.
Can anyone help?
Sorry I can't help you much SiB but I write this to show others have similar problems

Get the chamber/bolt checked with a GO gauge. I don't use small base dies and have never had an issue. What brand is the gun (or the BCG and barrel if it's a parts gun)?Quote:

Don't encourage the fuk head
It's a Core 15/magpul so it's probably made up of different parts. It should still function properly though. It's very accurate & have flattened turkeys out @ 300+yds with 62gn FMJ's(lasered distance). I'll take it to a gunsmith to have the chamber checked. The other cause I thought would be dirty shell cases but they're as clean as I can get them.Quote:

Make sure the Gunsmith is familiar with the AR15 Platform, some have less than no idea believe me.Quote:

I had they same problem with one of my AR uppers. The same load and cases would run fine through 4 different uppers but would not extract a non fired round easily on the problematic upper. Switched to using a small base die (redding in my case) and problem solved.Quote:

Sometimes the rifle loads & fires ok then a round won't slam home so I have to resort to the knife handle job to try to extract it. Even the ones I've reloaded from the AR's previous firings won't fit again sometimes.
