ar15 won't cycle.

I'm going to take it into a shop on Monday or Tuesday to see what their thoughts are

Can you manually move the bolt in and out on the carrier? It should have some resistance but not to stiff.

With the cam pin out yes it slides in and out with a little resistance. With the cam pin in it seems to be a little notchy and more stiff

have you tried this yet? really, i see a lot of issues narrowed down by just putting another BCG into the gun and seeing if that works.
 
Unfortunately not. I don't really know anyone else with an ar. My one buddy has a jp but wasn't too fond of the idea. I'm working on trying to find one to try.

I'm thinking about buying a second bcg that's a better more well known brand than what I bought.

Not to bash them too much, but we tried two AIM bcg's like the one you show in your pic, and we couldn't get them to chamber a round at all. They would get close and lock up tight. We originally thought we had bad chambers on our barrels until I tried a known good bolt and it cycled just fine. Called AIM and they recommended taking the o-ring out from under the extractor and trying to chamber a round again. That didn't work, so they said we could ship them back for replacement. I wonder if you might have gotten a bad one like we did.

Well you can bash away. I think you are correct. I was looking at the gun again. I put a piece of vacuum hose over the gas key and blew through it to try and get the bolt to move. I felt air on my finger back by the firing pin. So I grabbed a flashlight so I could see better and found this

You can see the gas key is not seated properly. With the poor lighting in my apartment it was hard to see.

I guess that's what I get for trying to save a couple bucks. I will be trying to get a refund.

is it just me or is that gas key not even staked?

psa has BCG's on sale right now for $89 and i hear about a lot of people who get very respectable product from them
http://palmettostatearmory.com/index.php/catalog/product/view/id/2321/category/332/

i'd be sending that [beeep] thing back to AIM.

if you want to go nice, LMT makes a nice bcg. but you're basically doubling the cost.


and when i suggested following up with the BCG swap, i meant to purely try someone elses bolt in YOUR gun, not yours in theirs. you can determine fault without putting their firearm at risk at all. simply test firing their bcg in your gun is so unlikely to do anything to theirs as to be completely off the table as a concern.
 
It looked staked when I got it. Now it looks like the bolts may have backed out. It will definitely be going back to AIM. I'm hoping I can get a refund but we'll see how that goes.

I'll be passing on the psa for now. I will be purchasing a quality one. It's unfortunate. I couldn't find any bad reviews about the aim either. Bcm,spikes,wmd,fail zero and a couple others are on the list.
 
Buy one from joebobs. Quality and reasonable price along with a good reputation to take care of any issues that most likely will not come up.

Hey joebob, let's see the PM discount re-instated.

I wouldn't mind a PM discount! Lol. Primary arms has fail zero NiB on sale for $110 for the semi auto and $127. Could have a full auto shipped for like $140. I'll check Joe bobs. I'm also going to see what a local shop has in stock and what kind of deal I can get from them

if you paid for a staked BCG then you didnt get what you ordered and should have no problem getting a refund. and quite honestly in this day and age can any company refuse a potential defective return? they have to know it'd show up on the internet at least somewhere if they started rejecting them.

for reference - this is what a staked gas key generally looks like, its kind of hard to miss once you know what to look for

i hope you can snag a buddies bcg and try that one in the morning. Nothing more stressful than a new gun that doesn't function. And the fact that aim sent out a batch of bad ones is a shame.

You have to be careful these days. A lot of "staked" BCG's are not really correctly staked. The test is to put a allen wrench to it and see if it will turn. A lot of companies are crimping them and they looked staked but will back out. They are also using substandard screws that are too brittle. This is even true of "higher end" BCG's unfortunately. Buyer beware.
 
That's good to know about bcgs. From now on I will double check mine with an Allen wrench before use!

Also I have a message in for aim I will let you guys know what I hear from them.
