I've got one. Good scenario marker. Shoots as well as any spyder clone. Yes it is spyder threaded. You aren't going to get an awesome rate of fire out of it. But then again, for scenario play that can be a good thing. Keeps you from running out of paint. Basically it comes down to if you want a marker that 'looks' like a firearm. After using mine at OK DDay I decided that, while it is overall a good marker, I would rather have performance than realism. I plan on hawking mine and picking up a project cocker to build into my ultimate scenario marker. I think the primary reason for my decision however was the difficulty I ran into in trying to mount a Scepter grenade launcher to the T68.
