Muldoon would win.
Why?
Because he's Muldoon
When life gives you lemons, don't make lemonade. Tell life I don't want you're damn lemons, and then squeeze them into life's eyes!

Muldoon wins; he's the chuck norris of the jurassic park universe
Nature doesn't deceive us; it is we who deceive ourselves.

Muldoon would win, he is not a badass, he is THE badass. Seriosuly, don't know why they killed him off in the movie.
IT'S TIME TO DU-DU-DU-DU-DUEL!!!

Muldoon every time. For reasons stated above, and because SPAS-12 is the best gun ever. And automatic weapons are for wimps.

Muldoon bias aside, it really depends on the range...
Close quarters: Muldoon 95% of the time.
Long range: Sniper 100% of the time.
Mulddon, BAMF though he may be, simply isn't equipped to deal with such long range prowess. Unless you meant TF2 sniper... In which case Muldoon 500% of the time. But assuming you meant creepypasta sniper, sniper 105% of the time.
Here, have a waffle (-'.')-#

Pretty sure he meant the TF2 Sniper (the one that throws piss in a jar).
I enjoyed the Creepypasta Sniper story, thanks for the link.

alright im gonna clear a few things up realy quick, first of ALLLLLLLLLLLLL the weapons i listed for the sniper are the weapons he has in the game team fortress 2, and the weapons that robert muldoon are equipped with are what he has in the film and the comics. (YES HE HAS A BOUY KNIFE, IT WAS EVEN ON IS ACTION FIGURE!) Second the reason they killed off Robert in the film was becaus all badasses have to die a badass way. as i once said "TRUST ME"

Well, muldoon if you're going by the comics...he would win. In the comics, Muldoon physically kills 2 biosyn mercenaries, one with his bare hands. I would say that Muldoon would win this one if it were close quarters given that he is supposed to be one of the best hunters in africa.
I still long to see a Muldoon vs Tembo fight.

No, still is kind of dumb that he died in the movie. Sorry, he would have never let the Raptors get too him in such a foolish way. It's just not his character, he observed the raptors often, so he knew the way he attacked, yet he fell for their attacks.
IT'S TIME TO DU-DU-DU-DU-DUEL!!!

Muldoon all the way! Im am sort of being biased since He is my fav character and SPAS-12 is my fav weapon but still.
He is Badass!
