did you get a 300 black out barrel by mistake?

Wow nogger u r dim

>>27921904
I have not shot it, or chambered it, but the barrel has the lil quarter inch lookin hole. Def. not a .30 cal.

It's freaky, I know, I called and asked the manufacturer if it was a mistake. They said no, and that is makes the end of the barrel stronger.

This is it:

got you. gas port position would also be another indicator.
anyway, i guess shit like this happens but thats weird. theres really no benefit that i can think of to having that combo.
id send it back if possible only bc 1/2x28 devices are more common, varied, and cheaper.

>>27921939
it even says right on the page "1/2x28"
>stronger
uh, okay.

They JUST now edited it. Okay, I swear to you guys, that the page said 5/8 x 24 a few minutes ago, I 'll even show you guys the email of whats going on

>>27921991
just send it back and get a new one

Maybe it fits an oil filter/solvent trap that way.
