Barrel Life of G21

[Creeping Incrementalism]

Does anyone have a rough estimation of the barrel life of the G21, which has octagonal rifling?

(I can already see it coming--assuming no kBs)

Probably at least a million rounds, but that could be way conservative.

 

[Creeping Incrementalism]

So they basically last forever?

 

[Rockstar]

No, they definitely don't last forever; they'll probably start showing a slight decrease in accuracy somewhere between the five-million and hundred-million round mark.

Oookaaaaaay...
