Spare Guns?

I would love a few weapons to help me run through this game again a little faster

I would like one that I can use now lvl22. Someone gave me one on the PS3 that lasted me through the whole game and did very well. Nothing super crazy, but like I said good enough to last me through the end. Combat Rifle w/ corrosive would be pref.

I would also like an awesome shield and one crazy combat rifle for after I finish the story to finish leveling faster and just screwing around.
