Working on finishing my SPR. I have a few BCG on my list. I was wondering if it really matters on what BCG I choose from in regards to accuracy. ( Did a quick search on this with no luck) I am trying to chose from a few BCG on the market. Spikes, BCM, and RR are on my list. Also I understand that the only benefit to a chrome BCG is ease of cleaning any thoughts from the hive here. |

BCM will be your best bet for a mil-spec BCG. RRA I'd stay clear of. Spike's I don't know much about other than it seems like a good product, but some people say they cannot back up their claims (I do not know one way or the other).
As for chromed BCG's- They've been around a long time and to me if they showed any real world increase in reliability everybody and their mother would have one by now. As long as whatever you buy is within acceptable tolerances you should not see a difference in accuracy. |

I've got a nickel boron Spikes BCG. It's built well and I've had no problems. It cleans easy, but on the shiney side.
I also have a Super-Duty Ion Bond BCG from Denny's/GTS that runs great is built better. It cleans pretty easy too. I also run a Colt and (improved)Bushmaster BCG's. I've had good luck with all of these. I haven't heard if a BCG could improve accuracy. I'm thinkin' as long as a good quality BCG is utilized...you're GTG.

Quoted: So basically if it is a Mil-spec'ed BCG and staked you should be GTG? Chrome and other fancy coatings are for ease of cleaning and lubricious issue's? Yup you got it. I'll pass on the coatings too. Not worth the cost or the small chance that you get a bad batch that flakes. |

Yes, I said to stay away from RRA because they do not shot peen the bolt nor do they high pressure test and magnetic particle test the bolt. If they are not performing these procedures you are buying a product that they and you are "assuming" has no material defects. A company like BCM/Colt that is high pressure testing (firing a hot proof load) and then magnetic particle inspecting for cracks/flaws is "assuring" you that there are no material defects in the product. In addition, why properly "stake" the carrier key yourself? The BCM BCG is within a few dollars of what the RRA goes for and, as explained above, is of much better quality. If a company can't take the time to stake a carrier key, what other shortcuts did they take? ETA: My point was that it is a matter of "Assumption vs. Assurance." |
| I think that after looking at everything. I am going to go with the La Rue BCG. The only reason I picket that over the Spikes is the Spikes is more. Spikes is a great company with some really good products. I have one of there NiBor BCG and I have run that things without a drop of lube for over 1000 with no issues. I am going with the LT due to budget. If that was not the case I would go Spikes! Thanks again guys! |

Spike's has posted publicly the certifications documenting HPT (high pressure testing), MPI (magnetic particle inspection), and carpenter steel composition of their bolts. Their "claims" have been more than backed up. |

As long as whatever you buy is within acceptable tolerances you should not see a difference in accuracy. I found this kind of funny, because on my last trip to the range, I had a problem with my new BCM bolt carrier with around 500 rounds on it. It looks like I'm getting some odd wear in the pivot pin track. Maybe maybe not. Anyway, I didn't feel like sorting it out at the range, so I just replaced it with my back up RRA carrier, which has over 10K rounds on it. Got back up and running. In any case, a bolt/carrier can affect accuracy, especially if it's too loose in the upper. On the day that I was having trouble with my BCM carrier, I noticed with my first group that I had to adjust my scope 12 clicks down and 4 clicks to the right to get back on zero. I thought it odd, but didn't think anything more of it. When my rifle quit running and I replaced the carrier, I then had to readjust my scope 12 clicks up and 4 clicks to the left to get it back on. Obviously I was having a problem with the carrier before the rifle stopped running and it affected the point of impact considerably. |

Their "claims" have been more than backed up. Hence why I clearly stated "I do not know one way or the other." I didn't say that it wasn't a good product, I did not say that it wasn't mil-spec. I remembered a thread awhile back speaking about Spike's may/may not be mil-spec. I didn't remember the outcome so I clearly left that open for the OP to research. In fact I even said "...seems like a good product,..." |

If the part was in spec, you would not have seen any difference in accuracy.
