| What are the differences between the A1,2,3 models |
|
A1 is the old style. Fixed carry handle.
A2 replaced the A1. Still has a fixed carry handle, but the rear sight is different. I believe the A3 is actually a full-auto (instead of burst) version of the A2. I might be wrong. Civilian manufacturers often use the designation A3 and A4 interchangeably for describing a "flat-top" receiver. AFAIK the military designates flat top receivers as A4. That's kinda it in a nutshell. You can get into a hell of a lot more detail though. I'm pretty sure there are encyclopedia sized books written about technicalities in what is considered A1, A2, A3, A4, A5. |

A1- Fixed carry handle, non elevation adjustable rear sight.
A2- Fixed carry handle, elevation adjustable rear sight with dual apertures. A3- Full auto M16A2. (.mil/le only) A4- Flat top, with detachable carry handle or BUIS. http://en.wikipedia.org/wiki/M16A1#M16A3 |
