Reply To: Info on FX Impact barrel help please.
No, the silver part isn’t separate.
I’m assuming it’s easier to crimp the twist on a smaller OD barrel to get the lands heights just right. 1/2″ 20 threads on the muzzel a sleeve is added.
zoom in on the 1st photo you will the crimp for the twist and it’s impossible to do that on a 14mm OD.
thats my impressions.
