Kit Badger only got nice things to say about Quickhatch from Rifle Dynamics, a real steel rifle you might want to have an airsoft version... "I've spent a lot of time with this gun, and it is Rad.  The Quickhatch by Rifle Dynamics...

First off, one of the coolest things you can do in the gun industry is a Build Day. The opportunity to go to a manufacturer and actually have a hand in building YOUR gun.  That is what I was able to do with Rifle Dynamics. I went out to Vegas and actually got to build my Quickhatch, which was amazing.

It is hard to get a more capable gun in this small of a package. A 9" AK in 7.62x39 with a folding stock.  And it is such a pleasure to shoot suppressed or unsuppressed with the adjustable gas block. Not to mention the Occam Defense Rail which lets you mount lights, lasers and optics. I outfit mine with the Q Fix Stock as well. I've shot this in numerous courses and competitions, to include under night vision. It is awesome."
