A shocker in soccer, pt. 2

Question

You’ll spar better with five letters;
I charge a fee, must be me;
A precise gun if I’m done;
And I’m a band to cross land.

What am I?

Note: This riddle takes the form of A shocker in soccer. The key is to take a gibberish riddle and figure out which second half of the line matches up with the first half before solving for the word or phrase. Note that I was not systematic with mismatching lines this time.

a train?

I charge a fee to cross land;
A precise gun must be me;
