whats the diffrence between an AR-15 and an m4??? anyone help me out???
An AR-15 is the civilian version of the M16/M4. The AR-15 does not have a select fire capability that either one of them has, which is the main difference.
I have 1 of each and all I see different is the barrel
M4 has an option for full auto and cost 10x times an ar15 haha.
The term M-4 is often misused to include 16" barreled AR-15's with the step cut in the barrel added to enable the mounting of the M-203 grenade launcher. A true M-4 is a 14.5" barreled flat topped M-16 with 3 round burst capability. The M-4 A1 is the same thing with full auto instead of 3 round burst.
You cannot buy a true M-4. There are none available to the public.
So the 16" would actually be a CAR right?
The CAR nomenclature has been tied to several guns. The XM-177 military designation was Colt labled CAR-15. Depending on the version it had a 10.5" barrel or 11.5" barrel.
The term CAR-15 has been used for many years to describe a 16" collabsible stock AR. Most would not argue with calling such a gun a CAR-15. The basic coniguration of the CAR/XM-177 is still available as the Colt Commando.
some ar15 makers have adopted the M-4 name for their rifles
mine is called an M-4 even though it's an AR, semi 14.5 barrel and flat top receiver
The first AR15s definitely were select fire and they still are made, though not available for civilian use.
Colt Armalite AR15 (pre-M16)
wow.. interesting guys!
Thank you for the Exellant schooling on guns!
that is sweet. i love how your serial number is crazy low.. you my friend are the man!
Not mine, it turned up at a LE agency that bought some M16s from the feds. Fortunately someone noticed it was very old and in great shape so too valuable to put out in the field. It should be in a museum.
You are right about that SN, jjfuller1. Very low so it must be one of the first that the Air Force bought back in 1961-63.
man I would love that ar15
