Before you order anything, there has been A LOT of drama going on at that company lately. The original owner/founder has left the company, so the Green Beret dude that is in the video is no longer there. He left because the partners were making him ship out orders that were incomplete or just wrong. Guys who ordered 5.56 cans were getting 30 caliber cans and vise versa. So you pay all that money for the can and you don't even get the right one! Also, they had a lot of issues with the cans design that has been worked out. Lastly, there were guys posting that the cans weren't meeting the advertised decibel rating if I recall correctly.
This is the 5.56 can that I really want but I'll have to wait and see what happens a little further down the road before I'll order one. But other than those issues, the can looks to be badass and is definitely the future for suppressors.
