Yea I've seen the .25's our club is going to restrict us to .20... I have to get with them and see if the .21 is legal or if I will have to go to the .18... I haven't found any one who sells the K$B .18 ? Some of the guys at the club rave about the older K&B .20 . I'll have to do a little more resurch... I want as much power as I can get without spending a fortune!!!
