T-Box Barrels

[A5BLASTER]

Has anyone used TBox Grendel Barrels or possibly another cartridge in there Barrel? If so can you give me info on accuracy, type rifling and possibly what blanks they use?

Ok I was finally able to see a old post from a couple years back. So got my info

They get talked up perrty good on the grendel Facebook page.

But from what I seen when I went to that website from your link, I'm not interested.

The way they list their chamber specs tells me it's not sammi and it's not 264 lbc either.

That's fine if that's what someone one wants but for my money I want sammi chambered.

I tryed the mutt chambers won't ever be doing that again.
