I'm more than a little ashamed to say that I joined this great forum back in March of 2007 in anticipation of beginning a 300 whisper SBR build and never posted....
Recently picked this project back up and need to get back up to speed. Lots of great information here!
No pictures yet but I'm almost there, final specs will be something like this:
SSK upper with 11.5" bull barrel (1:8 twist)
AAC Cyclone suppressor
Stag lower
Magpul PRS stock
YHM Rifle length light weight free float rail
