Alpha Precision Barrels

[Esab]

I have decided to give to ALPHA Precision Barrel a try. The intention is to swap my M3 liner with a real barrel.
Primary use is going to be with medium/light slugs shooting .25 cal 600 mm but pellets is an option as well
Any experience or suggestion with this brand? Should I choose traditional or polygonal rifling?

Lots of us Bulgarian guys are using the alpha precision barrels, especially for FX. Haven't heard one negative.
All guys I know use polygonal, all calibre. I've a 650 mm barrel shooting baby slugs .177 better than I ever dreamt.
The delivery from Spain is painless, my last order was 110 euro per barrel plus 8 or so euro shipping.
Definitely a risk I'm pleased I took.
