For practicality and over all everyday survivability what are the thoughts people have. I am considering a Rock River AR-10 LAR-8 or two WASR-10s. I am looking at straight practicality for a survival situation considering ammo availability should the SHTF. Pros for AR-10: Stable platform with a great all around round. Negatives would be the gun is a gas system not a piston system. Not a standard mag system for AR-10s AK is not as accurate at distance and the round does not have the effective range as the 308. The platform does not feel as solid as the AR-10 My opinion and would love people constructive thoughts.
