Has anyone used the SB Tactical HBPDW brace

[Up1911Fan]

I picked up one of the SB Tactical "Honey Badger" PDW braces awhile back. I know it uses a proprietary buffer system and they say the buffer weight is 3oz. Just wondering if anyone has used this brace or a 5.56 Honey Badger? I normally use 11.5" BCM uppers, but bought this with a more compact package in mind. Was considering the 10.3" Giessele Super Duty upper. Thoughts or experiences welcomed. Thanks.

Any updates? Saw they had a sale at PSA but also have an SBA3 kit NIB waiting to be used.
