Well last time i posted info i got called a troll but here goes ...
Both guns lowers are from JL billet http://www.jlbillet.com/
The guy makes amazing lowers . Both have tapped detent holes, bolt release spring holes so a set screw assures no flying springs. The 308 has ambi bolt release and both have set screws for trigger overtravel as well as a set screw that hits the upper takedown pin block to assure there is no play between the upper and lower to eliminate the need for accushim .
Buttstocks also JL billet weighs16oz.
