We posted previously about something coming from Hephaestus Custom and now they're making good with their promise of giving us a sneak preview of what they are working on. We have been waiting for AK bullpup for airsoft and this most probably the nearest thing there is. Called the "Thunder" their 6mm Gas Blowback Airsoft Bullpup Assault Rifle, it will be soon available which we hope within this year.

The photos show an engineering sample which you can find at the Hephaestus Facebook Page.
