Realistic list of spare parts to keep on hand

[MorphCross]

Good thread. I'm sub'd.
I need to put together a box or bag that has many of the parts recommended.

Pro-tip:https://www.amazon.com/Storage-Stack...05189252&psc=1 and print paper labels for each part. It doesn't take up much space on a work-bench.

Throw in a cam pin and a firing pin retaining pin too.

Very compact and pretty complete.

My thoughts are a spare bolt and firing covers a lot of bases, not really concerned about bolt failure but rather a broken extractor, worn out ejector, gas or FP, can all be taken care of with a bolt change in the field, no need to tear the bolt apart to install a rebuild kit. It's hard to have a extra rifle in your pocket but a spare bolt is easy peasy.

Exactly what I was thinking. Good post. It may not cover everything, but it covers a lot in a pinch, and the things I would consider to be most susceptible to breaks. An entire BCG with bolt would be where I would start.

True, and not to be a dick.... but why would this be necessary? Even faster is a second rifle.

If something goes wrong on a gun, I want to drill down to the issue right away.

So your argument that the BCG is an expensive part to keep on hand doesn't negate your argument that a spare rifle with optic and light is a more appropriate spare?

I've done both. Spare BCG is a lot faster since you don't have to sight in while everyone else is eating lunch.

Since people are talking about fixing guns at the range, I’ll throw this out: yesterday I had a stuck live round in the chamber, from a crumpled/folded case neck. I was not prepared with a Leatherman/Gerber type tool, nor did I bring a cleaning rod. Fortunately someone squared me away, so I was able to keep shooting. I’ll be putting a cleaning rod in my rifle case.

Given a M4gery, what spare parts, given normal wear and tear, should I keep on hand? I am thinking about operator level repairs/part replacement and parts that are likely to wear out and fail under normal (range) usage. So no armorer's work like barrel replacement or any thing that would require special tools. By way of example something like spare gas rings. I see a lot of lists but they seem to list parts that the average use would never replace and/or unlikely to break. So what I am asking is what is a realistic list.

That's easy.

Enough spare parts to build another AR.

No. What I'm saying is (for example) if you have 5 ARs, and keep 3 spare BCGs... you'll never need all the BCGs. One, mayyyyybe, on an outside chance. But if that happended, you could use it and repair the failed part, or order another one. I just think multiple BCGs is overkill. People can keep what they want... It's just not logical to me.

Better to have a few ARs and a single spare BCG.

At least one box like this.

Agreed except the accu-wedged and ambi-safeties.

Running low on ejector springs... and darn it you've mixed your forward assists and hammers into your firing pin compartment.

Otherwise that is a very complete set of spares.
