LW or an alternative

Gents,
I need help finding a good .22 cal 24″ barrel for my project. I contacted LW and was told they only ship 10 barrels minimum. I only need one though…

Getting a barrel in USA would have been a piece pf cake but it’s a different story here in Europe.

My design calls for a stainless steel model but if worst comes to worst I’ll take what i can get.

I think the AirForce/ GunPower Condor/SSS barrel would be OK (due to the 1:16 twist and quality in general) BUT i can’t find one here.

Could you guys suggest a store/gunsmith or any advice in general?
