I finally received mine, and after checking, the Drone Guardian indeed comes with a black mate Modified choke, identified by the three notches at the muzzle
As for the optic, the MPS that comes with the Drone Guardian is basically the “special simplified edition” of the Steiner MPS — a version made exclusively for this model.
Only 3 brightness levels, no NV settings, no auto-off, and a rotary switch you could probably operate while wearing oven mitts.
This is actually consistent with Benelli’s own promotional videos, including the one with Finnish champion Kim Leppänen.
What’s misleading, though, is that Benelli Defense shows the real MPS on their website, and even in some product presentations — including the TFBTV Show Time video — the Drone Guardian is displayed with the standard MPS instead of the simplified one.
