The damage boost is extremely subtle, and without a solid grasp of the DPS formulas, most of the overclock potential will go over a typical player's head. There's also that amazing -0.2 second reload, which turns the weapon into an absolute sustained damage beast.

I've just realised it's the most powerful overclock in the entire game. I'm not trying to be an elitist but if you don't have it equipped I'm kicking you out of my hazard 3 mission. Full Chamber Seal is far superior in power to everything else due to it giving free damage with basically instant reload time and no downsides! This thing shouldn't be in the game, it's literally overpowered and I still don't know how the devs thought it was a good idea to add this behemoth of an upgrade. Imagine having to wait 1 more week without having access to this beauty because this didn't drop in your weekly Deep Dive rewards, I would definitely kill myself.
