If you've been over in the build it yourself, or general discussion in the AR15 category... You'll know that in the last 24 hours there's been quite a bit of talk over what is really necessary in a bolt carrier group.

I've got my ideas on what is important... But I'd like to put up a poll and see what the general consensus is...

It has a C on it.

I've heard good staking of the gas key is one of the most important things.

I haven't been shooting enough to break anything and therefore have an opinion of what I want. Damn you expensive ammo

Nothing, I only won M1 Garands, M1As and AKs. Love this website, hate ARs!

I'm a big fan of the M1/M1A. If I had to get rid of both of my AR's to keep my M1A I probably would. But how can you "hate" ARs?

I like one with a fully shrouded firing pin, like the M16 style.

Oh, forgot to add that... and full auto, too.

+1. The only issue I've ever had started with a Smith Enterprise's LW carrier, and I've only use shrouded FP carriers since.

Most of the items in your poll are either irrelevant to reliability and performance, or are trivially correctable.

What's most important to me in a bolt is good quality steel, well made and most importantly properly heat treated so that it doesn't fail.

Chrome, nitride, etc etc inside the BC is important to reliable function.

Next would be an improved (balanced) extractor design.

MPI is irrelevant. Shot peening is probably irrelevant or possibly contra-indicated. Gas key screws can be staked in 10-15 seconds with a hammer and punch. Extractor springs and inserts shouldn't be an issue with a properly (re)designed bolt, in a standard bolt they're easily replaceable if need be - and correct gas system to barrel length solves the issue anyway. Don't know that I've ever seen a gas key break or fail so I don't know if forged vs. whatever else is really an issue.
