Any gas keys come loose, or are we calling them "poorly staked" because they don't look like someone told you they should? .... LOL.... You know it. If someone said it on the interwebs, it must be true.Uhh and where did you hear that??? |
I got mine, they forgot the firing pin

The staking on mine is adequate. A thin Knife line type instead of the more common center punch style. Material is sufficiently displaced into the knurled screws though. A great buy at the $80 price. This... It definitely is not "overdone", but is sufficient. I'll probably restake mine (takes 2 minutes with the tool). Great price for a spare (or spare-spare)

| I received a couple. They are very poorly staked.http://goo.gl/FD5Gqx |

I've had bolts with piss poor staking, no staking, and good staking. Never had a problem with any of them.
I am considering picking up one of these so I can put the m16 carrier in my M&P sport, and then have a spare bolt/carrier around. I don't know what the specs are on my sport's bolt, but if it ever break it will just go back to S&W for repair. |

Is it so hard to believe a group of carriers went out with poor staking? I bought two as spares, and the staking is so light no metal is making contact with screws. In order to prevent the screws from baking out, you need to displace the carrier key enough to make contact with knurling on screws.
I have 5 other carriers from CMT and a windham which are staked as they should. AIM is great and so is price, but staking should be checked as it appears some went out with light staking. |

Also, the firing pin in my two are SUPER loose, and they move around a lot. None of my other BCGs (and I have a lot) have firing pins fit that loose, which concerns me. Would hate to have an AD just chambering a round. |

No, it's not hard to believe at all. But based on the MULTITUDE of threads here about "OMG is my staking ok?", most people have no clue on what proper staking does, so comments about alleged improper staking are pretty meaningless. |
| Here is an example of what I'm talking about. The staking on the "questionable" BCG is fine - metal is displaced into the screws, and they won't back out. Shouldn't even be a question. |

Would hate to have an AD just chambering a round. Have you had a chance to mic these pins, or compare them to other "known" firing pins? Just curious if it is the pin or the channel that is off spec. Mine was normal and my staking was acceptable. Mine will be relegated to spare duty, but wouldn't be if suspect for any reason. Staking is something I have done before, and Aim allowed light staking on these. I believe an AD wouldn't happen due to these pins floating a little more than normal, but "if" it is an out of spec pin, is easily correctable. Aim has always stood behind my dealings with them, luckily my AIM BCG is acceptable. I'm not doubting you at all, just curious which part(s) allows this looseness. |

As Blain also states, the firing pin moves around like a baby rattle. Minor points, I would buy another for the price. Nothing I can't remedy myself. Does have the number 5 though.

<a href="http://http://i1049.photobucket.com/albums/s398/delicious66/AIMBCG_zpsf7478f63.jpg</a> Does the firing pin move around because the pin is out of spec, or the bolt channel is too big? Think that could pose a problem with function, or even cause a possible AD? |

No it's not. Some would like to see for themselves though. One persons definition of poor staking is different than another. I guess a different question would be, is it so hard to post one pic when you make a statement that could adversely affect product sales for a site sponsor? I'm not questioning your veracity. We just like to see pics when people say something is screwed up. This isn't a new trend.
Either way, it's no big deal. It's not like its tough to fix light staking. I'd be more concerned about not having a firing pin. Lol! |

Think that could pose a problem with function, or even cause a possible AD? AD... absolutely not. I have quite a few other BCG's and they all move/rattle to a certain degree. I don't see any issues with this one either. In all fairness this BCG was bone dry when delivered. After a good lubing it did slow the rattle down.

These were all hydraulically staked and torqued per military spec. I will get the information and post it here. I think people often times have and idea of what they think a properly staked carrier key looks like, and if it does not look like that, they think it is not done correctly. Either way, as with all our products if there is an issue call us. We support our products and customers.

My 5 minute review:
Cons: 1. Bone dry, no packaging, looked noticeably scuffed up (meh) like it was in a box loose with other BCGs. 2. Staking is a little light, but looks to be making contact with the screws, so probably ok. 3. Extractor spring looks flat ground on the base and doesn't really want to "snap" into the extractor. Comes out very easily and is a bit difficult to keep lined up right when reassembling the bolt. 4. Extractor spring/insert seem pretty weak, with the o-ring the extractor tension is about the same as a BCM without the o-ring Pros: 1. Price, duh 2. Finish and materials look good. Chrome lining seems thick and even. Once oiled up thoroughly, it looks like any other quality phospate BCG 3. Fit is good, everything seems built the spec'd dimensions. I did NOT have a loose firing pin. I didn't really rattle it before lubing, so that might be why. No weird wear marks on the BCG or gun that suggest interference or anything. Brass looks normal. 4. IT WORKS!! Bottom line, it runs flawlessly in both my guns so I'm happy for the price. |

As for the staking, it looked like they used a scribe or instead of a stake punch, the stake is very deep and sharp. Not really an issue, just interesting. |
