It does weigh a little more then the actual kits' rifle but I guess not enough to weigh the arm down. Heh before I actually got this laser rifle add-on weapon I though I was gonna have to prop it up with something.
Yeah the good old super powerful laser rifles. My only real reason I never used those was the fact that every shot was a massive drain on the Core's energy stores (and I was always boosting or in the air). I miss the days of the linear rifles, those things packed a pretty decent punch for being so portable and lightweight. Very cool model all the same and I do love the design and look of the gun.
I remember that mini-Karasawa knockoff from Crest in AC3 -> LR didn't have that low shot velocity problem, though it wasn't nearly as powerful either. It's too bad they nerfed the Karasawa so much. It was the standard big ass mecha beam rifle. A BFG for mechas. That should be beyond awesome.
