The AR-15 is a lightweight, intermediate cartridge, magazine-fed, air-cooled Armalite Rifle with a rotating lock bolt, actuated by a piston within the bolt carrier or by conventional long/short stroke piston operation. It has been produced in many different versions, including numerous semi-automatic and select fire variants. It is manufactured with extensive use of aluminum alloys and synthetic materials.
The AR-15 was first built in 1959 by ArmaLite as a small arms rifle for the United States armed forces. Because of financial problems, ArmaLite sold the design to Colt. After some modifications, the redesigned rifle was adopted as the M16 rifle. In 1963, Colt started selling the semi-automatic version of the rifle for civilians as the Colt AR-15. Although the name "AR-15" remains a Colt registered trademark, variants of the firearm are made, modified, and sold under various names by multiple manufacturers.
The AR-15 is based on the 7.62 mm AR-10 designed by Eugene Stoner, Robert Fremont, and L. James Sullivan of the Fairchild Armalite corporation. The AR-15 was developed as a lighter, 5.56 mm version of the AR-10. The "AR" in all ArmaLite pattern firearms simply stands for "ArmaLite Rifle", and can be found on most of the company's firearms: AR-5, a .22 caliber rifle; the AR-7, another .22 caliber; the AR-17 shotgun; the AR-10 rifle; and the AR-24 pistol.
I thought you were a friend of mine but I was wrong
You tried to fit into the arms where I belong
You moved right in behind my back
Everyone knows friends don't do that
I thought you were somebody I could trust
You always said you were happy for us
How could you go and break my heart?
When you knew all along he was mine from the start
He is everything to me
And you know we're meant to be
He's my baby
Don't mess with my love
Take everything I own
Ooh just leave that boy alone
He's my baby
Don't mess with my
Mess with my love
Don't mess with my love
You came right over and looked in my eyes
You said the stories were rumors and lies
And I wish I could believe in you
But I'm sorry to say he told me the truth
He is everything to me
And you know we're meant to be
He's my baby
Don't mess with my love
Take everything I own
Ooh just leave that boy alone
He's my baby
Don't mess with my
Mess with my love
Don't mess with my love
Friends don't do what you do
There's no excuse
I'm so confused
I thought you cared about me
But now I see
All you care about is you
He is everything to me
And you know we're meant to be
He's my baby
Don't mess with my love
Take everything I own
Ooh just leave that boy alone
He's my baby
Don't mess with my
Mess with my love
