Tuning airguns with fx barrels and liners

[Jimmy001]

my newest ceation is my hatsan blitz 25 cal with fx slug barrel.And new trigger assembly with 1 lb pull.

I have a superior liner in my RTI Priest. 

 

[Odoyle]

I have an old 22 regular FX ST for a Crosman 1322. 

A 25 Impact MK2-A for IDK yet and couple slug and pellet liners for 25 WC2 Compact that I haven't decided what to do with yet.

 

[Odoyle]

Now I would think the FX current pellet liner that shoots both pellets and slugs for a 22 Daystate Redwolf HP or Safari with the Daystate programmer or Heliboard...maybe even a 25...

I have a stx liner on one of my rapids, i am not sure how long it will stay, I can’t say it’s any better than the original LW barrel, It is much lighter but also less stiff even though it’s got several layers of carbon tube.

I have a 700mm 22cal Slug A liner going on my Kral NP-500 for a heavy slug gun. 

 

[COSTAS4597]

Six different barrel configurations for my FX ELITE.

Cal .22

500 mm ST / 600 mm SLUG A / 600 mm SUPERIOR STANDARD.

Cal .25

600 mm ST / 700 mm SUPERIOR HEAVY / 700 mm SUPERIOR STANDARD.

Haven't tested them all yet. 

Next one will be a .22 CZ (AA S200)

I assume these aren’t drop-ins, some machining required? Sounds like it may be easier on some guns than others?

Correct. I had to make a brass thimble that matched the OEM barrel with leade, breech oring and transfer port plus made a threaded end for the muzzle. Both .001" undersize of the liner. Add three evenly spaced bushings along the liner then heated and press fitted the two ends with a length of carbon fiber tube in between. Made for a very stiff barrel that simply goes in place of the factory one.

I have a .22 700mm STX liner on my LCS SK-19. I had to make the housing. It seems to be a little more accurate than the original barrel .

I’m currently in the process of converting my 30 cal Hercules Bully to accept a 600 barrel and a slug A liner in 30 cal.



with all the corrections to the scope rail I did 3 years ago and the addition of the bottle to shroud clamp, this is the last loose end I have left on the quest for better accuracy.



the biggest one thing I like about the Bully is the 30 cal polymags fit just about perfect in the 10 round mags. And if I choose slugs later on it’ll be ready for them
