No bolt and bolt carrier included?

To be honest, I really doubt there is much "matching" going on.....and I will venture to say that there is really no matching at all. This is not like a M14 or bolt action they can work on the mating surface between the bolt and receiver.
The AR head space is based on the barrel extension, the bolt has nothing to do with it. There may be a slight chance of bolt lugs breaking or damage to the barrel extension but it is highly unlikely.
I have swapped bolts on uppers with thousands of rounds on them and fired thousands of rounds in that state, it simply is not an issue for the average shooter who doesn't fire more than 1K rounds in a year.
That being said it is always a good practice to keep parts that can wear together.

This is true and we're talking about weapons that have been firing since the 80's and have countless rounds down range. I have an 89 rifle sitting beside me right now and who knows how many bolts have been through it or where the original bolt group is. It still shoots accurately out to 300.
Sorry, but for forensics, maintenance and other reasons, C7 bolts are marked with a number that matches a specific gun... at least until last year...
if you move ar15 bolts around you should have a set of chamber gages. they don't cost much and it is a safety measure. the m14 rifles that were sold here have the serial number on the bolt. this is because the us national guard armories stored the bolts in a safe and the gun locked in the rack.

I beg to differ. I have personally seen my bolt go into a bin and come out a different one. Not to mention I've seen a couple of Colt marked carriers and bolts in service weapons that were NOT original. Maybe it's supposed to work that way but I assure you it doesn't.
Like I said in my post some units may make an effort to do this but it is no longer the norm. IIRC some early bolts had the ser# on them but like angry eyebrows said most only have the C or the stylized D on them now.

Most likely just cheap...if you wanna call it that. As stated by someone before, it is much easier to move an upper with a $600 price tag then an $800 one. Not to mention if the seller plans on buying a new upper lots of companies uppers don't come with a bolt group or charging handle.
Maybe so but in the military the serial # is for tracking A and B class parts it has little to do with mating up to a particular firearm
Unit Rifle teams try and keep the rifle and the bolts together
M14 bolts are not interchangable between rifles they do wear into that particular rifle and are not easily swapped between other rifles requires a armourer to fit the bolts
Not unit rifle teams... ALL the rifles in the Armoury...

Yeah, can remember them doing that with the C1s,Don't recall if the same bolt [ Breech Block]always got back to the same rifle though,we use to walk around with the damn things in our pockets .
really how many here are going to pay for a over $300.00 or more on top of the price for a incomplete upper so it can come with a bolt and a charging handle. Hands up any one
