Hi,
When you order a complete spare bolt carrier , it comes with the manufacturer oil or grease inside, and if you are not using that bolt for the next 5-10 years, how do you store it. 1-As is. 2-Clean it , oil it and store it. 3-It doesn't matter. Thanks. |
| well it depends on where you will be storing it. if its in a house closet where the humidity it controlled as is should be fine. if the humidity is really high there I might reccomend packing it in axle grease and storing it in a sandwitch bag possibly vacume sealed. that should keep it indefinately. you would want the sandwitch bag because I can imagine the vacuming process getting messy and potentially compromising the seal if it gets squeezed into hte sealed areas. I keep my parts as is in a foot locker with all my gun parts and tools. I check them every few months as I'm going through things and if they seem dry I put more oil on them. |

A spare bolt, without a headspace gauge is a great way to kaboom yourself. A better idea would be to have 2 bolts and rotate them every 3-500 rounds so that the bolts and barrel extension wear together. umm.......NO new bolt + old barrel = ok clean it, lube it and store it |

And I've been advising folks to use their extra and still "clean" bolt to swap-out their dirty bolt for in the middle of extended missions and then clean them both when they get back to camp and the ultrasonic cleaner.

So who is for bolt swapping.
In my manual , it says do not switch bolts between rifles. Let say 5k-10k rounds later , my bolt is broken , so what I do? 1-Put my rifle in the Garbage. 2-buy a new complete bolt carrier . 3-Do not pay attention to the manual. By the way , the rifle is LMT MRP CQB 16". Thanks. |

You are advised to not switch bolts between rifles as the bolt and the barrel extension wear together. If your bolt breaks put a new one in, and check the headspace. |

Sorry but, Are you telling me, if my bolt breaks , 1- I should buy a new bolt and a new barrel. 2- how much play I can afford between the new bolt and the old barrel. Thanks. |
| If your bolt breaks, put in a new bolt; keep the barrel. Generally it's advised to use headspace gauges ("GO" and "NO GO" or "FIELD") to check if headspacing is within safe limits. I have seen someone else post here that they have just put in another bolt and fired the gun held high above their head. I don't know if I'd do that. |

ML Mark: How critical is checking headspace on a new bolt/old barrel combo? Is it safe to swap in the field if you can't check headspace? Thanks, RMD |

The maintenance FAQ at Maryland AR15 Shooters' site states, and I quote, "there's no concern about a new bolt in an old barrel. Heck it's going to be larger (no wear) than the old bolt and there will be less headspace". Here's the link. It gives other info. as to when and how often to use a field headspace gauge.
http://groups.msn.com/TheMarylandAR15ShootersSite/maintenacefaq.msnw I see a lot of differing opinions on this. When in doubt HEADSPACE might be the most conservative answer. |
