I didn't read any other pages cept the first one so idk if ppl posted these ones yet.
1.The TCP fires faster when you jump, just like with nades. (I'm talking if you semi-auto it not just hold the trigger down.)
2. I think this works with any weapon but I'll use the SMAW as an example because I found this AT with this weapon and because its reload is long as hell.
-This is only works if you're near an ammo box for reasons which will be obvious.
How to do: After you fire your SMAW and have to reload, switch to your other weapon before it reloads, then go open the ammo box and switch back. Your SMAW should be ready to fire

It cuts the reload in half, AT LEAST. It really depends on how close you're to the box and how fast you're switching to your other weapon.
