Poseidon inner barrel

[Isamu]

I saw a post on facebook (yes, I know, facebook) from a guy who builds DMRs about a barrel I didn,t know, poseidon barrels. 

 

The concept is that a ridge runs in the lower part of the barrel to generate a "cushion" for the bb to maintain spin more time. People say it is a rip off from an idea from Hunter seeker 5 and what their own sciencetific knowledge makes them wonder, but besides that, there is no real hands on experience or anything remotely cientific.

 

So, I wonder if someone here in arnies have experience with them or some real information.

 

Thanks =)

Got some more information about the barrels, they are advertised as 6.05mm and found a long and informative video

not buying the air cushion part, but I think that groove will help centering BBs against the hop bucking nib

I can't help but think, that a leak at the bottom will decrease pressure from that direction instead of increase it...
