I posted a request in another area of ARFCOM, but got no response. I know that most of the 700 series are not considered retro but I thought maybe someone could help me flesh out this listing I have of the Colt 700-Series.

What I have so far is based on Colt's Armorer's Catalog with a bit thrown in from some of Capt Richardson's posts and from Andy K's list gleaned from Janes. There are a few entries I have found that are not listed in Colt's Armorer's Catalog and I have included them.

The post is formatted as follows:

Colt Model Number followed by a hyphen
Colt Designation followed by a hyphen
Fire Selector followed by a hyphen
Lower Receiver Type / Upper Receiver Type / Rear Sight Type / Barrel Type
followed by any notes including any known US Military designations

The "E2" terms, listed at the bottom of the list and are asterisked , are of my own use and not offical Colt designation.

Note this list doesn't treat the Colt 703 as the gas piston prototype.  That number was initially assigned, but was recycled.
