FX Crown STX Superlight Barrel Caliber-Change Kit
Like many FX airgun models, the Crown series can be changed to suit the user in a wide variety of ways. One of the most appealing is their ability to quickly and easily switch between various calibers. These Caliber Change Kits allow you to do just that! If you bought a Crown in .22 caliber, and now you want a .30 caliber gun, all you need is the Caliber Change Kit and a magazine (sold separately.) No longer do you need multiple guns to accomplish your airgunning goals. One gun and a few of these kits are all you need!
The Superlight STX barrel upgrade, which weighs in around a half-pound lighter than the original STX barrels, uses a newly engineered and imagined barrel housing to hold the STX liner. The liner is no longer housed in a long steel tube, but rather is now placed in a very sturdy barrel attachment section that results in a more rigid barrel. Including an STX barrel liner, shroud and pellet probe, these Caliber-Change Kits are easy to install by the end-user. They do require some alterations to your rifles settings, but this can be easily achieved thanks to the various external power adjustments that are standard on the Crown series.

Lighter, easier to get around in hunting situation, much more rigid than the 700mm factory barrel.
Things I would have changed:I had to make a separate order from a different retailer to purchase a moderator to go with the barrel ..... It would've been nice to be able to purchase both items in the same order.
What others should know:One must realize that you will be giving up some velocity and energy switching to the shorter barrel.....So putting in some time shooting over the chrono and dialing in the trajectory is a must ...
