What to choose...I have interest in a Ruger 10/22 for tinkering. Now I'm seeing the Kel-Tec RMR-30 prototypes and am seriously interested. Then there's also the thought of building an M4 lower and adding a specialized upper (AR-57 / 9mm / .22lr). And then.... there's the wish I could get the Skorpion EVO III which looks like a sexy little beast. I fear the closest I'll get to that would be the RONI-G2 system.
In this post I'll go more into detail about options with the above systems and similar systems that grabbed my attention.
