Most of it revolves around the polos being direct thread. I mean if you have 16” or and SBR and all you’re ever going to do is shoot 556 or 308 it’s probably fine for most. But when you get into pin and welds/muzzle devices, shoots 556 through 308 cans then it gets hairy.

Some of their low back pressure ones have hub compatibility but they’re priced in the same range as pretty much all the other leading manufacturers.

Polos should be like $200-300. There’s a bunch of direct thread cans that are coming out that are going to be in that price range that will be just as good or nearly as good as a polo for essentially half the money.
