AR-15 Spare Parts
What spare parts are good to have on hand for an AR-15? Parts that wear down or break and might need to be replaced? Thanks.

A complete spare bolt is a good idea since it is easy to swap out and addresses several common issues (extractor, ejector, gas rings, broken lugs).
You can also buy a set of AR15 springs pretty cheap - they don’t break or wear out often but the little detent springs get mangled by inexperienced users swapping the stock, or launched into low orbit during obsessive detail cleaning. Plus that usually comes with a spare buffer spring, which is a wear part that will need to be replaced and impacts function. Those two things will handle a lot of common AR issues at minimal expense and hassle. |

I keep a complete bolt carrier group and complete lower build kit minus furniture in my 3 gun box.

Spring kit, bolt, cam pin and firing pin if you just keep less than what Reynolds said

Another AR for while you are working on the first one. Then maybe just one more. And another....

Here’s the reproduction cycle of the AR15. You buy one. You start replacing parts on it with nicer parts/parts that are more suited to what you want. One day you are looking at a PSA complete lower sale at $130 and you notice you have enough “leftover” parts to make a whole new AR. Then you start modifying that one and the cycle repeats itself.

Firing pin, and firing pin retaining pins.

I’m accountable for my fair share of space junk. The worst is when you’ve launched some critical part and spend the next hour with a magnifying glass searching by grids.
That’s why I use a ziplock bag or other transparent bag to catch them now. |

Here's what I keep on hand:
two or three lower parts kits (one is a good start), 2 complete bolt carrier groups, two complete bolts, three sets of gas rings, two bolt upgrade kits from BCM, a spare buffer tube, two or three buffer springs, a couple trigger springs and hammer springs, two gas tubes, three firing pins, three firing pin retaining pins, a couple cam pins, take down pin detents and springs, and a partridge in a pear tree. Get started with what you can and slowly you'll accumulate whatever you could need. Then as others have mentioned, just build another AR to have on hand. |

Charge handles--I'd keep at least two spares on hand at all times.

I never seem to have spare parts...they end up being another AR.
However, I seem to have one too many BCGs right now, hmmmm.... |

Spare parts ... for replacement?
I thought extra AR parts were just seeds that grow into new ARs...

I stash just about every part. Some double and triple, especially springs etc.

Spare Bolt... ( or a whole BCG, since those are so danged cost effective. )
And this "Revival Kit" has a good balance of parts. http://sionicsweaponsystems.com/stor...3-carrier.html |
