What causes this to happen? Gas issue or FCG issue? I took my AK out for the second time ever and its still having the same problem. It fires, extracts and chambers a new round but it doesn't reset the hammer. It does this every shot except once today when I was able to get off 2 shots. Gun is a M92 PAP. Modifications are ALG AK Trigger and Tapco retaining plate which I installed before shooting it originally, which in hindsight may not be the best route to take. That said I'm sure its something that can be fixed, just not sure where to start.
