The receiver is marked Magnum Twelve and was manufactured by Miroku in Japan, with the NT serial code confirming 1996 production. The forged steel receiver and Special Steel barrel reflect Browning’s robust construction approach for the Auto-5 series.
The 28 inch barrel is vent-ribbed and topped with a brass bead for a clear sight picture. It is threaded for the Invector-Plus choke system and is chambered for 3 inch shells. The Invector-Plus system is not interchangeable with Standard Invector or Invector-DS chokes.
Operation is the classic long-recoil Auto-5 system, paired with Browning’s Speed Loading feature and a left-side magazine cut-off. Capacity is 4+1 when unplugged, with a plug reducing it to 2+1 for migratory-bird compliance.
The black synthetic stock includes molded checkering and a ventilated rubber buttpad, with a 14.25 inch length of pull. Rollmarks read: "BROWNING ARMS COMPANY MORGAN, UTAH & MONTREAL, P.Q. MADE IN JAPAN." and "BROWNING AUTO-5 INVECTOR-PLUS SPECIAL STEEL 12GA. SHELLS-3" - 28"."
