As they continue with the countdown for their release of their "Germanic Flames" which we guessed to be an HK45 GBB Pistol, RA-Tech released another batch of photos confirming it is indeed an HK45. Based on the Tokyo Marui HK45 GBB Pistol, this looks like a full steel slide set for the pistol, heavy on detail such as marking and giving the pistol a 2-tone look. We're not sure yet if there are upgrades for this as we're just looking at the externals.

You can view more photos at the RA-Tech Facebook Page.
