CALIBER EXCHANGE SETS

IMPORTANT NOTE:

FX uses a medium strength tread locker to fixate the transfer port to the barrel to prevent the barrel coming loose. We strongly advise you to use a tread locking adhesive like Loctite® 2400 also

Changing from a larger calibre to a smaller calibre 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 calibre, 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 calibre;

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

 

.35 CAL BARRELS HAVE A DIFFERENT THREAD ON THE LINER LOCK NUT. AND A SPECIFIC CONVERSION TO GO DOWN IN SIZE FROM A .35 IS NEEDED.

ALSO, FOR EG A STD 30 CAL BARREL CAN NOT BE CONVERTED TO .35 FOR THE SAME REASON.

FX LINERS AND MAGS ARE NOT INCLUDED IN THE CONVERSIONS.
