What is this piece that I took out in the pictures for? It’s in my .308 Super Lite stock. My T1x with a heavier profile barrel does not have that piece. Wouldn’t it be better to not have that and have the barrel free floating? I haven’t tried it to see if that piece touches the barrel as I haven’t reassembled the guns yet (I am installing Spartan gunsmith adapters so the epoxy is drying). Just thought it was weird to have that piece in there.
