Finished it awhile ago, but thought I'd share.
Did my first a few years back, 20" blackhole weaponry bull barrel build on Matrix receiver set. Accurate as snot, but heavy as poop. Sold it and moved on and learned a thing or two in the process...

2nd build used an Aero M5 match set and 16" Faxon taper profile barrel. Build was relatively lightweight, accurate, and fun to shoot...but was just missing "something".

3rd build, went with the Aero M5E1 set this time, used a Faxon match 5R fluted 18" heavy barrel, SRS recoil system, and this build is pretty much perfect. Amazingly light recoil for a 308, very accurate, and comes in at only 8lbs8oz without a mag (but with sights and handguard rail panels ?)
