been gone for a bit and just found these threads. the new clip feed action is also available as a bare action.
4473 forms have 3 options on then, long gun, handgun & frame.

strikers in rear grip stocks have the same trigger options as rifles. screw spacings vary for striker, target and rifle actions so the stock maker needs to know what spacing you have. Neal made the stock and can send you pictures of what he has available. One of my actions is also timed and trued with an SSS trigger.:)
