Great guns and eats most ammo! I've had good consistency with CCI Mini Mags but again it will eat most ammo. As a small business that carries all Tippmann Arms products and accessories I've had the chance to shoot all models and they all have run flawlessly with an occasional hiccup here and there but due to either a dirty gun (my bad on not cleaning before shooting) or shooting full auto with sub sonic ammo. .22LR just doesn't have the umph to load the next round on full auto in some cases. All in all great guns.
