I suspect the below comment from that page is correct:I wonder why they picked the Honey badger to rule as an SBR. What makes it different from an AR556 pistol or 300 BO pistol with the SBA brace? This is not good.
The “Honey Badger” has a “custom made pistol brace” different than other SB Tactical braces. It seems that the bats are using this insignificant difference to re-con-screw “the intent” of its use to become a “shoulder stock” rather than an “arm brace”. This is purely speculation as no one really knows what goes on inside a bat’s brain.
