>>64030448 (OP)Anon, in general these discussions are way lower quality (assuming this isn't some fucking bot yet again) if you don't actually say where you are and what you specifically want to use it for, under what conditions.
Anyway hadn't heard of an integral version of the M18 before, looks like a europe gun? From an American perspective, and while I love integral suppressed stuff, in a rifle form factor I'm not seeing a real advantage at initial glance vs a Tikka T3X with a separate can. Particularly once stamp costs go to $0 next year. Barrels wear at a very different rate from suppressors in typical center fire calibers, to an extent that matters far more than a typical pistol where the whole thing effectively lasts forever. 6.5cm barrel life for PRS is typically around 3000-4500 rounds depending on firing schedule, and maybe more like 6-7k for hunting, whereas a suppressor can last tens of thousands of rounds. One might also want to change calibers, move to a different chassis, have different barrel lengths or contours/materials for different usage, etc. Integral makes all that harder.
All that said, the M18s have always been ok enough hunting guns. Assuming the suppression was competent vs cans (worth noting that 30cal has pretty wide variations in performance if you look at pew science or similar measurements), and you're ok not having any rail built-in, it's a tidy looking package.
