As Birdog noted the Scalarworks replacement rail (SYNC-01) with an RMR co witnesses well with the factory M4 ghost ring sights. It will only allow the RMR to mount though. https://scalarworks.com/shop/integral-mounts/sync-01/

I would also recommend the Scalarworks LEAP mount. I got one to mount a Trijicon RMR to the top rail on my Sig MPX Copperhead K 4.5. Very good quality and light weight. The ratcheting knob for mounting is easy to use and works well. It is flush mount with no protrusions to catch on stuff. It can be installed and removed by hand with no tools. They have different heights. I called with questions before ordering and got the owner on his mobile phone while he was driving (call forwarding is good). He was patient and helpful. I also got the RMR mount to replace the rail on my M4. Good people and good equipment.

I bought my first Benelli, an M1 Super 90, because it looked cool at a LGS and I wanted a semi auto (I still have it). When the M4 came out I thought it was too expensive and waited and waited. Seeing the LE version available to the public I wanted one and finally bought my 11721 M4. It was still too expensive, but I watched on Gunbroker for a while and felt I got a good price. Already spending more anyway on mods.

Good to know, thanks. Like you, I've read a lot about this. I've used Wolfe before on other weapons now I'll be looking at them for my M4.

I'm a new member and wanted to say hello. I own a M1 Super 90 (bought new in the 1990's) and just bought a M4 LE, the 11721 with collapsible stock and 7+1 mag tube. I just got the IWC light/sling mount for the mag tube with a Surefire M300C Scout and IWC QD sling socket for the stock. I've been doing a lot of reading and there is lots of good info here. I'll learn a lot and hopefully contribute. Thanks
