Can someone explain the difference, if there is one, between an M4-type rifle and a CAR?

also, is it pronounced "kar" or "see-ay-ar"?

car for carbine

A M4 usually has m4 feedramps and a cutout for the m203 grenade launcher in the barrel.

CAR as in CARbine.
M4 is a modernized CAR; specifically with respect to the barrel profile, flat top receiver, and M4 telestock.

M4 is the specific military (and commercial) designation of a specific current production carbine family.

CAR is an acronym that was given to more than one Colt variant/weapon families in the past but is most widely known as an abbreviation for "Colt Automatic Rifle" (and most recently: Colt Accurized Rifle, a commercial offering). CAR is also used as a generic term for the older style AR carbines.

M4 carbine.

I like to call mine a CAR or carbine, because it has a Hbar no 203 cuts, and the smaller carbine handguards, and it has the smaller carbine telestock. It also doesnt have the M4 feed ramps just standard rifle ones. Mineis basicly a lightweight set up with out the lightweight bbl. On the other hand IF i had the M4 handguards and M4 telestock and M4 bbl with 203 profile, I would call ita M4 or M4forgery.

I'm sure all the retro guys know the exact difference. Barrel length Sights and furniture are probably the biggest differences.

*ahem* When someone says CAR, I picture an old-style 4-position stock and a 16" barrel.
When someone says M4, I picture a barrel with an M203 cutout, six-position stock, and a flattop.

Edit to remove the inaccurate pics. D'oh!

Yes, the flattop is a feature of the M4, but you have pictured yours with the removable carry handle mounted on it, which might confuse noobs like me.

Those sneaky devils at Bushmaster...... <--- Me

Try again?
(taken from advntrjnky, thanks!)

M4 (real deal from Colt, no carry handle, I doubt many ppl run a flattop with nothing on it )

I've been wondering this for a long time. Thanks for asking!

CAR-15 can mean three things depending on what context it is used in.

1. Is a generic term for a carbine sized AR-15
2. A name that describes the first eight AR-15 models that Colt offered in the 1960's standing for Colt Automatic Rifle
3. Or it refers to the light support variant (light machinegun/Colt model 650) of the AR-15 as Colt Automatic Rifle

An M4-gery is a close civilian approximation / reproduction of a military Colt M4, and has a 14.5" bbl with perm 2" FH, or a 14.7" bbl with perm A2 FH, or a 16.0" bbl with removable FH; all with a cosmetic section of turned-down barrel just in front of the FSB. M4 handguards are thick and oval shaped in cross-section.

A CAR is a 16.0" barrel with removable FH with no cosmetic barrel thinned section in front of the FSB. CAR handguards are round and thinner in cross-section.

The above pics by sic_ness are good examples.
