Got a free Linebacker Prime and this was my first build. You can only fit 4 and a half tons of ammo but it is sufficient for most matchs. There is a discrepancy between the mechlab and smurphy's in the weight, I only fit 4 tons in smurphy's. Also have a clan active probe so you can target despite ecm. First game I played with the build not too bad.
Running something similar like this, dropped a half ton of ammo and placed a light TAG int the shoulder.
