I apologies as this isn’t going to be a particularly picture heavy update as my connection isn’t that fast where I am at the moment.
Felix at GunsWorkShop.net has sent in an email to day that they have made a custom HK416 style AEG that’s for sale in their shop at the moment.
For those of you not familiar with the designation it’s an M4 style HK body with an AG36 launcher fited to the underside and a RIS railed front end. CHeckout their website for the shots of their new creation.
