There are other mounting options out there as of 2019. when I replied to this post in 2016 before sumtoy started making mounts, plus a couple others who have made mounts since then...there really at that time was no other option for an 870 except the saddle mount, or simply adding a picatinny, weaver, base plus the mount itself. Personally...I still live the 336 mount. but if it was a new build id probably use sumtoys mount system just for the side protection that it has to keep stuff from hitting it if you knocked the gun over.
