Review:
This is one of the best barrels you can put on a spyder, good accuracy and low price. If you want a rifled barrel that is a little better go for the empire twister. Also the psycho ballistics aradus is a great barrel and if you can buy it used for $35 i would go with that but this CMI is also good.
Conclusion:
Good all around barrel for woods ball and speed ball. and for $25 it's a good buy.
