Green Label vs. Blue Label Preban Colts

In the midst of this tragedy, I have chosen to preoccupy myself with happier thing lest I go out and do something I will regret later.

So what do I do? Attempt to learn more about preban Colts:) But, I can't find any real detail about these two and what makes one or the other better. Can you help? Details about features and why they are better or worse would be appreciated!

I also would like to know if there is an advantage to either a large pivot pin hole vs. a small pivot pin hole?

Green Label, Blue Label, White Label.

A way of classifying groups of Colts based on the color of the label on the box. If I remember correctly, they were actually shipping blue label and white label at the same time for a while, although there were subtle differences in the models offered. All very confusing, and distracting.

Have you done a search here?

There used to be a lot to read on the subject. I don't know if their archives contain the threads anymore, but it's worth a look.
 
The only firm rule with Colt is "never say never."

However...

As a general matter, "green labels" have:

- bayonet lugs
- large pivot pins
- no sear block
- small fire control (hammer, trigger) pins
- old (pre M16A1!) style lower with no mag fence or reinforcements

Pre-ban "blue labels" have:

- no bayonet lug
- small pivot pin
- pinned-in steel sear block (early) or unmachined blocking area in lower (later, like more recent Bushmaster lowers I have seen)
- large fire control pins
- M16A1-style mag fence/reinforced lower

For a good history/summary, see the Rec Guns FAQ at: http://www.recguns.com/IIID2b123.html Also check out: http://www.biggerhammer.net/ar15/

The advantage of the small pivot pin on the blue label receivers is that you can often swap out the screw parts for the USGI push-pin/detent parts (or have someone drill it out for you if it wasn't factory drilled). Also, it will fit small-pin uppers without the somewhat kludgey adapter.

The disadvantage of the blue label receivers is the large fire control pins and parts, but spares are cheap enough that you could keep plenty of both style on hand for the future without much cash invested.

Realistically, I don't consider the sear block a disadvantage -- either it's not a problem, or you can solve it without a lot of trouble -- whatever suits you. This topic usually starts a conflagration, though!
