I got a gen 2 entry but didn't really like the OEM railed hand guard. It's super solid and drop in, but its not actually Mlock and you have to screw pic rails to it, and having three layers of mounting is...sub optimal. I've read rumor's that the gen 2 hand-guards are to drain water away from the piston and gas ports for some military contract, but I am not raiding a oil rig from a semi submersible any time soon so I'd rather have the dirt and physical protection of the original's, and I can larp with it better.
Here is the before and after.
I used the Freedom Fighter Tactical hand guards as I couldn't find both Benelli OEM's, just the left side for some reason. But comparing them side by side the FFT's are of a higher quality plastic and fit better.
You also need these three parts:
Benelli M4 & Super Black Eagle 3 Spring Washer
Benelli M4 & Super Black Eagle 3 Washer
Benelli M4 & Super Black Eagle 3 Retaining Ring
Also, the MSP/IWC light mount will NOT clear the gen two hand railed handguards, the light body will by about 2mm at the end threads but there is no way of any tail cap of any type to fit.
Also drop in, and now I can larp Ready or Not in my barn with the cows.
