I own several of their V2 Nitride bcg's, all have been 100% after several thousand rds.

I've got one of their lightweight carriers.  I'm fairly happy with it.  The gas key did come loose after about 500 rounds, but I fixed it myself.  They offered to repair it, but I didn't want to pay shipping back or wait for it to get done.

+1 on the V2. I've had no issues with mine either.

I have a bunch. On a few guns I've had to install the BCM extractor spring upgrade kit and I've re-staked all of them. They've been flawless after that.

+5 on the V2 nitride.    
Mine have all been GTG.  I've recommended it to a couple of co-workers and theirs have all been GTG, too.  

Disappointing news on the V2's though.  Bryan at AIM said they were having vendor issues on this particular BCG and it might "done" (his words).  
Hopefully, they can get their issues straightened out or find another vendor to keeps this version alive.

This is the one I own. It's been great so far.

Ive had their NiB, standard phosphate and V2 nitride. They all functioned well for me but the NiB flaked on the front of the top carrier rails after a few hundred rounds. I traded the NiB and V2 away with their uppers awhile back.

Still using the phosphate with a Sprinco extractor spring and it's ticking along just fine in a 16" Freedom upper.

I personally didn't see a huge difference in cleaning between the 3 finishes, except the NiB when really wet actually does just wipe clean with a paper towel.

Just purchased one of their NIB groups yesterday. Hopefully I don't get the flaking issue. That's why I didn't purchase the PSA one. Quite a few commentssaid they had issues with them flaking. But have not heard a lot of bad on the AIM.

There's probably no way to know absolutely how many AIM BCG's are out there, but other than factory delivered BCG's in factory guns, I'd wager that they have provided as many aftermarket BCG's as any other outfit out there.  As to who makes them?...probably not one manufacturer.  I'm speculating here totally, but it might explain how AIM offers their BCG's at a good price.  That doesn't mean it's a bad thing, but it may also be impossible to predict performance/reliability with certainty.  That said, I have 3 of their BCG's...phosphate, nitride, and NiB.  Even the finish on the NiB is still pristine after hundreds of rounds.  I think running suppressed is one of those issues that can challenge some NiB finishes from what I see occasionally here on the site.  Fail Zero and WMD and maybe some others seem to have a better handle on the NiB process.

I have a phosphate one, I haven't fired it yet.  Looks and cycles nice, waiting to check headspacing.

I have several Aim BCGs and they've been great. I love how the nitride ones are so easy to clean.

I got 2 Nib complete BCG's recently from Aim, but just havent had a chance to go shoot those guns.

Patiently waiting for them to get in more of the Evolution BCG's.

I had a NiB one that would work in my older M&P15 but wouldn't work in my Newly built home build. Swapped bcg and all was good.

I have a EVO 3.0 and the only issue I have so far with it is, it will not pop open my dust cover when I'm pulling the charging handle.  The dust cover does crack open by about 2MM or so.  If I let the bolt slam forward by releasing it, so far, that action will then pop open the cover.  I do not know how it functions yet.  Hopefully find out soon.

I just got one of their NiB EXO bolt carrier groups and I'm very impressed with it. I'll be taking it to the range this weekend!

NiB in a few guns, all flawless.

it was a couple years ago, and I honestly cant remember. I have built a few guns and run into so many different problems since then. I just remember it was my first build and I swapped bcgs with my M&P and both guns worked after that. I still have the Aim bcg in the M&P. I do remember that the Aim Bcg seemed really tight in the lower it was malfunctioning in. could have been something as simple as not enough lube, but I was pretty green with AR's.

Have you seen a FZ or WMD to compare it to? I might grab one.

I have not unfortunately... but if you would like any specific pictures taken for your own comparison then let me know.
