I asked Live Free Armory some questions regarding some specifications of their LF308 Battle Rifle. This is the information they sent me:
Patterned after DPMS High profile Gen 1
The buffer is 4.3 oz
The buffer spring is 308 carbine length
Buffer tube depth is 7 inch
Gas tube is midlength
Gas block area is .750
Gas port diameter on the barrels we are currently using are .076
I read over the thread on Barrel Gas Port Size and Gas tubes, barrel gas ports, and buffer weight. It seems like the buffer is on the lighter side and the gas port is kind of small. Does that sound right?
