Ive been using hoppes 9 oil on my piranha and its completely shot all the O-Rings on my Piranha. Now insted of going out and playing in my friends woods this weekend ill be setting at home waiting for the mail. The guy at Piranha said they it is made for Tippmanns but nothing was mentioned to me on the box. THANKS HOPPES 9!!!! This is just warning all you PMI people not to touch the stuff.
