M4 hammer questions


Recommended Posts

I have a newer production m-1014. I’m doing the parts count deal so I can install the long mag tube worry free. I have a FFT firing group kit and I just came across a Geissele hammer, new, never out of the psckage.

I remember some years ago, FFT hammers were showing premature wear. Has this been corrected? I’m thinking of simply using the Geissele hammer with the Benelli firing group.

Thoughts on this?

I’d probably just get the A&S frame and drop a FFT kit in it. The newer polymer frames seem to have been made to a different spec. The hammer tends to hang up on the disconnector. You might see some deformation over time on the FFT which is similar to the oem hammer. This wear doesn’t cause any functional problems. 

The Geissele hammers are nice since they’re using their magic tool steel that is extremely hard. You can mix it with the FFT disconnector and trigger if you wanted. That the setup I have in my ‘best’ M4.
