Noticed that one of the newly released photo’s of one of the AR’s not only show the Bump-Fire stock as we have heard, but also a 60 rd Mag as opposed to the standard 30 rd. May be out there, but have not seen it mentioned regarding what appears to be a Surefire 60 rd Mag. Twice the firepower before mag change.

The photo of one weapon he used looked like a Surefire SoCom muzzle brake. I use those and there is NO muzzle rise when firing with them installed.
