FX Crown STX Superlight Barrel Caliber-Change Kit, 500mm .177

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.
