After some 6 months the extended barrel arrived from the factory via Steyr USA today.
Nice work and threading 130mm length if I recall. Soon it will be mated with a TROS can and a range report will be forthcoming.
I will advise if Steyr will be stocking these in the next day or so and if not what steps anyone who wants one will need to take.
Please post pictures when you get a chance. What's the price on those, and where can I get one? Also, can you get a thread protector for it? What calibers does it come in? I'd be interested in getting one for my M9A1.
