[ARCHIVED THREAD] - Need advice on models

Posted: 8/5/2004 5:15:26 PM EDT

Hello everyone, nice board\subject you have here.

I want to build an AR-15 and have been looking though ALL the options for sights, uppers etc.

Is there any resource that describes and pictures how an "A2" flashider compares with an "A3", or "A2" upper vs "A3" upper?

I can really be confusing when you don't know the difference.

Thanks in advance
