I have an Olympic Arms ar-15, 16" barrel, carry handle and the rear sight has to be adjusted with the tip of a FMJ round. It's very basic. What is it? An M4? I've not been keeping up with (remembering) the terminology. |

Quoted:
sounds like you have an A1, A2, has carry handle and adjustable knob sights A3 is a flat top M4 has Barrel cut out for Grenade Launcher A4 is the flattop. A3 is a variant of the A2 with full auto instead of burst. Many people consider both A3 and A4 to be flat-top receivers. Including Colt. |

Quoted: ya, it's an M4 if you have the colaspsable buttstock dont worry about the A2/A3 bullshit as it pertains more to the .mil weapons, not the civilain stuff Yep colaspsable stock, I've also added a cheap bolt on rail underneath the fore grip in order to add a vertical fore grip that pivots. The vertical fore grip also keeps my spare gas rings, ejector and firering pin. |

ya, it's an M4 if you have the colaspsable buttstock dont worry about the A2/A3 bullshit as it pertains more to the .mil weapons, not the civilain stuff But does it have the M203 cut? Without it, it wouldn't be an M4 'clone' - it would be a CAR15. BTW - an M4A1 would have an A2 style upper. Although I've seen C7 (A1 sights w/case deflctor) variants with the M4 profile barrel, and the Israelis have some so configured as well. |

Although I've seen C7 (A1 sights w/case deflctor) variants with the M4 profile barrel, and the Israelis have some so configured as well. by that logic it would still be called a CAR15 unless it has burst. I think its safe to say that any AR15 with a colapsibal buttstock and a 16" barrel can be called an M4 Spellcheck is your my friend
