i recently got the weapon and tried it and it is ridiculously good, two or three hits to kill e level three sentry and just run around the ting and poof, no more sentry, it is so usefull, provided your the pyro, it is so annoying when your an engie and you just built every thing when a pyro manages to sneak up real close to the snetry without it going into the line of fire and BOOm no more sentry, it is so annoying, but hey, i guess it also helps engies with the fact it can kill sappers
