A spare BCG is nice, but you could get by with just a spare bolt if you are concerned.. BCGs are not all $250, especially now. Which one do you have?
You could just get the extractor parts, and gas rings, if you are really worried about back up. Buy some ammo and mags. Shoot tons. |

You can buy BCG's for under $100... (Bolt carrier group)
I have a few extra bolts with cams and firing pins, but no extra carriers. A carrier will likely not break unless your gas key fails, but I'll risk it. |

You dont need a carrier, the bolt is the part that breaks.

I think it is very important to keep a spare bolt for you primary fighting rifle. Usuallybi would check headspace before dropping new bolt in if u shoot until the first one breaks.

It's always good to have spare parts and now is a good time to buy. You can get a Stag M16 carrier with HP/MPI bolt for $125. The bolt alone is $50. There's cheaper stuff out there but Stag parts have never let me down.

It came with a spare bolt, springs, cam, cam pin, and firing pin. I have since added a couple of allen keys for my rail and accessories. Although I've never had to use anything in the kit (except the allen keys) it's nice to know I have those spare parts if I need them. |

A spare bolt is probably more useful than a spare complete bolt carrier group (complete carrier with a complete bolt). The carrier itself is about the most rugged part of an AR, though it does have the gas key attached, which is probably the only carrier assembly part that can be damaged short of trying to damage the part. I'd go with a spare bolt, a spare gas key and two correct screws for the key. If you have more than one AR, keep at least two keys (with screws) handy.

It is very rare to hear of problems with a bolt carrier.
Screws and/or gas keys more often, but still not that many considering the number out there. A spare bolt carrier is the fast way to get back shooting if a screw breaks. A spare bolt (with the headspace checked) is never a bad idea and having spare BCG parts in addition is also a good idea. Good BCG’s are available for far less than $250. Overall I would not say a spare BCG is a necessity. You are much more likely to need some of the consumable parts long before the bolt or carrier. |

I have one spare BCG, another spare bolt, and a couple of extra firing pins. I also keep an extra o-ring or two, plus a few firing pin retainer pins (cotter key) as most of this stuff is very inexpensive...and when you are gonna need them, you're gonna NEED them. Like another poster mentioned above....I'm afraid my spare BCG is going to eventually morph into a complete rifle someday. |

As of last week, I had a spare BCG from BCM sitting in my spare parts container. Last week, I got bored and slapped together another stick using what I had in spare parts. I like having at the very least 1 complete BCG in waiting to be used. So later this week, I plan on ordering maybe 2-3 more as I want to build another complete upper next week when I get home.

Yep... leave those damned things laying around and they grow from a sweet little carrier into fire-breathing beasts. Beats the hell outta me how that happens. On the serious note though if a bolt breaks when it matters most you will be under severe duress. This is when you will drop little parts, so that's why I keep a bolt, couple of retainer pins, a firing pin, and a cam pin in storage in the rifle. The little stuff won't break, but it will sure run off scared when you need it most. |

My spare BCG's turn into spare rifles. At $90 for a BCG, it's hard to justify just buying a bolt for $70. I'll probably pick up another spare at some point.

Bought my first AR and trying to determine which items are necessary to have. I read somewhere (maybe on this very forum) that some folks like to carry a spare bolt carrier assembly. Just curious as to how important you guys think this is. I realize its only an additional $250...but if its not completely necessary I'd rather spend that cash on ammo or something else. Please advise. Thanks Typically the point of failures are the bolt assembly (extractor or firing pin or gas rings) and most likely the cam pin. Chances are if you get a breakage it'll likely be the gas rings or the cam pin. Either way the failure rate should be never. Perhaps once in your life. The only reason to carry a spare bcg is to rock and roll without going home. Just more of you go to the range, it breaks, and now you have to go home. Otherwise if you have patience just order it online. However with the current political landscape, no telling if you'll be able to get it on the day if it breaking. Personally the only spare part you should concentrate on is spare magazines. Typically when a "scare" happen the most common thing to go up and become rare is magazines. Followed by actual rifles and full auto bcg. |

I have a couple of the $80 BCGs from Aim Surplus as spares, at those prices I'll just buy the whole BCG. I also have what amounts to several spare LPKs. I think it's a good idea to keep an extra supply of the various springs, detents and pins on hand in case something breaks.

The most common items to break in a bcg are the extractor, gas rings, cam pin, firing pin, or the gas keys but if they are staked you should never experience it.
My advice is to get a spare bolt and cam pin. The bolt should have a spare firiing pin as well. However with good parts they should never break, until you hit the 12k round count or so. Even military troops don't run around with spare bolts and they do fine. Just make sure you check headspace when you swap bolts or barrels, though. Little chance of having issues but better safe than sorry. |
