My question would be whether or not it uses an AR-15 or AR-10 sized BCG. If it's only AR -15 size then I don't feel they were trying to address the real issues, just jumping on the bandwagon.
I can see the appeal, but I doubt I ever buy one. Use the cheaper more powerful ammo in the system/design that's more accurate. Time will tell for it, but like what was already mentioned I'll just keep my AK.
