The Onyx Waterfowler 3.5 configuration combines stout 3.5-inch chambers with barrels specifically marked for steel shot, making it a purpose-built waterfowl variant within the 686 line. The 28-inch barrels carry a ventilated top rib and a single front bead for a clean, consistent sight picture.
Barrels are marked "EXCELSIOR – HIGH STRENGTH ALLOYED STEEL" and show the complete Italian proof suite: Gardone crest, PSF, and FINITO, along with a boxed "BB" date code. Additional barrel and bore markings include 18.3, KG1.540, and assembly code "26732 – BB S M O." The importer mark reads "BERETTA USA CORP. ACKK. MD".
Controls are classic 686: a single selective gold-colored trigger and a top-tang safety with integrated barrel selector. Ejectors are timed, and mechanical condition notes indicate solid function with good barrel fit and good firing pins.
The walnut stock features checkering, a pistol-grip profile, a narrow field-style forend with a schnabel tip, and a Pachmayr White Line ventilated recoil pad with white spacer. Sling accommodations include a QD sling swivel stud in the buttstock toe and a forward swivel under the forend/barrel. Length of pull measures 14.0 inches, with a slight right-hand cast-off.
The gun is set up with extended knurled stainless choke tubes—LMOD in the top barrel and IC in the bottom—on barrels threaded for chokes and marked for steel shot. Capacity is 2 rounds.
