I was looking over my liners and noticed that my Crown 177-380mm pellet liner is 1:28 twist?? No mention anywhere I can find of this twist for 177?
Is this some kind of unicorn?

FX FX barrel liner twist rate....for the umpteenth time?

According to the european airguns site, the FX .177 380mm comes in two twist rates.
However, there seems to be just one part# for an FX .177 380mm.
So, when ordering an FX .177 380mm, you would have to specify to the dealer which twist rate you want.
FX really should have different part numbers for different twist rates.

Welcome to FX, a company that is too dumb/lazy to change part numbers, even a simple xxxxx-3 or -5. The only way is to pull the barrel and look, they DO, surprise, mark the twist rate on it. You can pull a cleaner through it and count the revolutions and measure distance but it's easier to pull the soda straw. Just my opinion

The "FXB" numbers delineated in the above screen capture are NOT part numbers. They are ARTICLE numbers that cross-reference back to drawing numbers and cross-reference forward to PART numbers.
Article number FXB 20362 will cross-reference backwards to all drawings for each FX model that uses this article and forward to every Part Number assigned to a 4.5 caliber, 300 millimeter liner.
There are individual Part Numbers for every twist rate - lands & groove deminsions produced for Article Number FXB 20362.

You should contact AoA.
They may be able to cross-reference your Crown's serial number to the applicable Drawing & Revision, locate the applicable Drawing Number for the liner which in turn will cross-reference to the applicable Article Number with assigned Part Numbers.
The Part Number for your specific liner will indicate if it is still in production and current distribution status.

Yeah ok, so the average user that is looking at the part number on their soda straw or what ever is supposed to be digging around to do all of that. Nonsense I've got soda straws all with the same part number but different twist rates, I hate to break it to FX but in all of my years in manufacturing we NEVER EVER did that, they are unique parts and should have a unique number, even if the front ones are all the same.
