-Why does the Barrel Length option top out at 22"?

We intended for these barrels to replace the factory contour barrel for the original CROSS Rifle.  Given the rifle's light and compact nature, we did not want to offer barrel lengths that would betray the rifle's original design intent.  


This barrel must be fit to your receiver to the proper headspace by a qualified gunsmith using the proper tools and measuring equipment. The finished barreled action must be test fired with factory ammunition. Failure to follow these warnings may result in injury or death.
