What are the differences between Stoeger M2000, 3000 …
The recoil spring is moved forward around the magazine tube like the M3, allowing the stock to be cut to any usable length. The cam pin setup in the bolt is not based on any previous version of the Inertia bolt design. The M3000 and 3500 share most internal parts, differing primarily in that the 3500 is longer to accommodate 3-1/2 inch shells.
