Does exactly what it says it does - Griffin Armament SN-ACH 15 Gen 2 Charging Handle

If your gun is trying to kill you slowly by gassing you to death, this is the charging handle for you. The SN-ACH does exactly what it is advertised to do. After installing the charging handle, I experienced very little to no gas blow back. I am left handed so I do get some for the ejection port if the wind is blowing in the right direction, but nothing directly to the face from the back of the gun. The only negative thing I have to say is that the charging handle is not a true ambidextrous handle. Pulling on the right side of the charging handle does work, but it does so by taking the tension off the locking mechanism. It does not physically open the lock like it does when pulling on the left side. Being left handed, this approach works just fine and doesn't out weigh how well the charging handle works at mitigating gas blow back.
