What does XM stand for?

In relationship to the XM8 I would assume?
Kinda like the XM16 when it was being evaluated for service?
The X means it is being evaluated (expiramental I think) The M is just common to military weapons.

It's just a more expensive model of what the AR is.  They probably gold-plate the barrel or something.

'Fraid not.

From Armalite's website:


WHAT DOES THE "AR" IN AR-15, AR-180, OR AR-10 STAND FOR?

There is a common misconception that AR stands for "ArmaLite Rifle."   This is untrue.  The AR-17, for instance, is a 12-gauge shotgun.  Early designations like ArmaLite 10 were shortened to simply AR-10.  The AR refers to ArmaLite.

The ArmaLite Division of Fairchild developed the AR-15 in 1959.  Fairchild licensed the rifle to the Colt's Patent Firearm Manufacturing Corporation, and Colt's assumed the AR-15 trademark.  Early Colt rifles were marked "Colt ArmaLite 15."  Even today, the designation to that Colt brand rifle refers, somewhat embarrassingly, to ArmaLite.

AR -> Armalite

NOT 'Assault Rifle', as only one of the preceeding AR-series weapons was an 'Assault Rifle' (the AR-10).

And as for the rest:

X -> Experimental

M -> Model

M16 -> Rifle, Model 16
XM8 -> Experimental Carbine, Model 8

I am just a real novice at this history stuff, but I own a Bushmaster CAR 15 XM. These were produced during that gray preban period. Seems the allocation of the model called for a shortened barrel(11.5) with an extra long flash supressor(5.5). The gun is relatively light weight and in my notice tactically orientated(cut me some slack on the last comment)

I suspect it's actually a Colt issue. Doesn't colt hold the trademark on AR-15. The others have to use a different designation.

Colt just needs to accept the fact that they did NOT invent the AR-15/M16.  They are just a govt contractor.

Ahhh...sure. Actually I believe the Marines had some influence here
with the M16A2. I don't really know how much Colt has actually done
unilaterally to improve this platform. But I be interested in being enlightened.

I do know if you add an HK M416 upper....then it's "perfect".

Colt may not have invented the AR-15 but it owns the name, and that's all it takes in the USA.  While the rifle is generically referred to as the "ar-15", the actual name "AR-15" is owned by Colt, bought and paid for from the original Armalite.  Anyone marking their "ar-15-type" rifle "AR-15" is going to be in court pretty quick.  About as fast as if you decided to start a bus service and call it "Greyhound", or build a clone of a Corvette and called it the "Corvette", or start a bank and call it "Bank of America".  Trademark protection is covered by law.  It doesn't matter what the product is.

For this reason, anyone else making an "ar" calls it something else.  XM-15 for Bushmaster, M15 for Armalite, PCR-15 for Oly, etc.

Colt actually did most of the imporvments to the AR-15 system in house, on their own dime.  They only had the original AR-15 when they bought it from the original Armalite.  Things like the various bigger and smaller versions were developed by Colt.  Like any company trying to get the government's money, they do things that the customer wants, but even then it's usually their engineers that come up with the item.  

Some things the government actually just comes out and says it needs, and Colt just built it and put it on.  Some things the government says it wants to have done, and Colt had to invent a way to do it.  It's no different than anything else really.  

Colt had the A2 type handguards in the 70's and offered them to the government, because they were stronger, and you only needed one (i.e. they weren't left and right, they were identical top and bottom), and had developed the A2 sights (which are actually a variation on the original AR-10 sights)  about then as well.  The Navy department, on behalf of the Marine Corps, did the engineering of the A2 profile barrel.  There were a host of other improvements that Colt offered that the government just gave a nod to, and a bunch that the government itself invented and told Colt to put on there.  

Colt developed the M4 from it's own carbine line that it had based on the XM-177 work from the 60's, which again was mostly Colt engineering.

It's a trade name basically.  Federal uses "XM-193" to identify the ammo they sell on the civillian market.  It meets M193 specs I beleive.

The answer is "NO" you are not shooting experimental ammo.  A company can call anything it makes, any name it chooses (unless someone owns that name already).  It's just a name in this case.

It has nothing to do with the way the government uses "XM".
