How do you fit this thing out? I have hardening / rammer (improved aiming alternative) / bond vert stab

I absolutely hate it, on paper the gun looks so good but in reality it handles worse than my IS-6 even with a bond vert stab fitted. I have a series of games in this thing where I do 400-800 damage before I get rushed and killed because my shitty DPM makes me a non-threat
