I just ordered one of the lightweight Spikes uppers from AIM, complete with BCG and CH, but was wondering if I should replace any of the BCG or maybe just the bolt itself with BCM?
Would it be worth replacing any of it, or just the whole thing? Thanks in advance. |

| Man thats a good deal! I had my heart set on picking up the BCM 14.5" mid length upper with the pws fsc556. There is like a $130+ difference between the Spikes and BCM set up that I wanted. Guess I'll grab whichever is back in stock first. The BCM hasn't been in stock for months. |

No need to replace anything....They are equal...Both are TOP of the line BCG  Like the post above me a spare is nice to have.ORLY. I've read a lot of differing accounts of Spikes independent certifications. I doubt the OP would have a problem with his Spikes, but labeling them on par with BCM is bit of a strecth in my opinion. |

I'd say the Spike's BCG should be fine. If you're really worried, buy one of the BCM extractor upgrades. I'm not sure if they use the same extractor springs or not... But the bolt materials should both be up to snuff as they're both HPTed and MPIed individually and are made from the mil-spec grade metal. |

Go to Spike's forum in the Industry section and see the certifications yourself. There's a tacked thread at the top of their forum. |
| I replaced my Dpms bcg With a BCM bcg. and felt it was a worthwhile expenditure. (Kept the dpms as a spare). You otoh have a bit better piece of kit. Id say it was a must for my peace of mind. Totally optional for you, but i'd change it if it was bugging you. You need to be in tune with your rifle from a psychological perspective too |

Whole lotta fail in this response. I've read a lot of things on the internet too. If I believed every one of them, I would be broke because I would have sent all my money to Nigeria waiting for my eleventy billion dollars that I won in their lottery I didn't enter. Seriously OP, Spikes and BCM are both fantastic. Buy the BCM or another Spikes as a backup. ETA - Grant, is that you? |

Why is that a stretch? BCM is good and all, but wow there are other options out there. Spike's has all the certifications...how are they not equal? |

(Not that I doubt that BCM meets the specs… just sayin’) As far as I know Spikes is the ONLY company to back up their specs with published certs. BCM Fan-Boy nonsense… |

| Before this thread goes full retard with the Kool-Aid drinking fanboys. I would like to tell the OP that a spare bolt is a great idea. Not a replacement but a spare Matter of fact, a spare extractor and spring or two is a good idea too. Spikes, BCM, Colt yadda yadda. Just pick a good one from a reputable company. Doubtful theres that many different shops actually making the damn things anyway. |

Oh… well perhaps I stand corrected. Please be so kind as to provide a link for these illusive certification documents of which you speak… complete certification documents… not just a snippet from a destructive barrel test from 2007. Something along these lines... But as to the OP’s question… If you can get a good deal on a BCM bolt then get it as a spare. As others have said… having spare parts is a good idea and BCM is good stuff… can’t go wrong with their products, but I certainly see no reason to replace the Spikes bolt. |

You can go read the certs yourself. But you, like mostly everyone else citing independently tested and proofed certs, are probably unqualified to fully understand them no matter what is being tested. I know that I'm not qualified to interpret the docs. I do economics, not metallurgy. That being said, it all comes down to trust in a particular brand. BCM makes a damn good bolt. They have a good reputation and their affiliation with top trainers speaks volumes. However, their bolts are not made out of some unobtanium multiple degrees superior to other companies that are marketing to specs and QC. You trust BCM more, and for good reason. That does not make them materially better. Unless you can prove otherwise, we are all fanboys........... If you are an engineer or metallurgist, please understand that most people are not. I am making a general assumption that most folks could look at the certs for a bolt from BCM and one from Del-Ton and not know wtf one was the BCM bolt based on reading certs. |

Funny thing about those certs on bolts. It only means they should make it atleast 5k rounds. As far as I can tell. |

Most bolts and carriers are made by the same 2-3 companies, Microbest makes apx 20,000 bolts a month and 30,000 carriers they are all the same and get sold to many different shops.
They are a DOD contractor, the same bolts go into Colts and FNs. It doesn't matter if it has a BCM laser etched on it or the Spikes spider they are the same bolt made in the same building. Some of the cheaper companies use 8620 commercial grade bolts. |
| As has already been stated your stock Spike's bolt is no different in quality or function from the proposed BCM. Shoot the stock Spike's rifle with confidence. Having spare parts on hand is never a bad idea. Shop around for best price on a Spike's, BCM, DD, Colt, ect. bolt carrier group and keep it on hand as a spare. |
