FX Crown Caliber Exchange Set with V2 Dual Hole Transfer Port and High Flow Pin Probe By Huma-Air.
This caliber exchange set with V2 dual hole transferport and high flow pin probe makes it posible to change the caliber of your FX Crown (with standard barrelkit) with the use of your excisting barrel sleeve and barrelshroud.
The set excists of a stainless steel barrel attachment with our V2 dual hole transfer port, a liner lock nut, a high flow pin probe and the supporting o-rings for the optional FX liner inside the barrel sleeve (the liner itself is not included)
By using this kit with your excisting barrelsleeve and shroud, you can change the liner of your FX Crown with a liner of the same length and a different caliber.
This set is not compatible with the FX Crown Superlight barrelkit, it only suits the normal barrelkits.
FX uses a medium strength treadlocker to fixate the transferport to the barrel to prevent the barrel coming loose. We strongly advice you to use a treadlocking adhesive like Loctite® 2400 also
Changing from a larger caliber to a smaller caliber does not require any modifications to your shroud or moderator, because the bore of the shroud and moderator will be large enough.
When you go upwards to a larger caliber, you need to check the bore of the shroud and moderator, and if needed open up the diameter of the bore of the shroud and moderator to match your new caliber;
Minimum bore diameter for a fixed shroud would be:
Cal .22 = 6,5 – 7 mm. bore
Cal .25 = 7,5 – 8 mm. bore
Cal. 30 = 8,5 – 9 mm. bore
Dual Hole V-2 Transfer Port and High Flow Pin Probe Included:
The V-shaped transfer opening makes sure you will have the maximum and smoothest air passage area. The middle support bridge divides the transfer port into a dual hole port and the middle bridge makes sure the pellet or slug nose cannot fall into the enlarged transferport hole, but will be guided smoothly by the middle bridge into the barrel.
This set also includes our stainless steel Pin Probe.
Together, this set will give the maximum airflow behind the projectile.
These sets are developed for slugs and pellet use! and can be used in combination with our power tuning hammerspring
The liner itself is not included, you can order the FX Superior Liners here or order the FX Superior Heavy Liners here
Any modification done to the airflow of your rifle, will affect the entire setup and performance, you might need to re-adjust the settings of your rifle again to get the best possible performance.
