9mm AR barreled rechambered

[yoni]

I want to get my CMMG 9mm Banshee chamber reamed to 357 sig.

Does anyone have a good gunsmith they can recommend for this?

You could try Randall at ar15barrels.com. He doesn’t list .357 sig on his site but we could probably give you some suggestions.

I found a guy in Iowa, that I get the feeling all he does is rechamber 9mm barrels to .357 sig. His lead time is 3 to 4 weeks, so I am not the only mad man . When I get the barrel back I will post a review of it here.
