12ga Browning Magnum Auto 5 Barrel with Invector Chokes
Browning Magnum Auto-5 12 Gauge Barrel with Invector Chokes
So you want to add a quality replacement or additional barrel to your Magnum Auto-5 without tracking down one-off parts. This barrel gets you there. A genuine Browning Magnum Auto-5 12 gauge barrel, fitted with the Invector interchangeable choke system. Vent rib. Made in Japan during the later Magnum Auto-5 production run.
12ga Browning Magnum Auto 5 Barrel with Invector Chokes This is not a Light 12 barrel. First, the Magnum Auto-5 action is specifically designed for 3-inch shells, with a different feeding and ejection mechanism than the Light 12. Next, Magnum barrels will not fit a Light 12 action, and vice versa. Finally, this barrel gives you full Invector choke flexibility — swap chokes for different hunting applications without changing barrels.
Will this 12ga Browning Magnum Auto 5 Barrel with Invector Chokes fit my Auto-5?
Only on a Magnum Auto-5 action. So Browning explicitly states in their owner’s manual that 3-inch Magnum 12 gauge barrels will NOT fit a Light 12 gauge action, because the feeding and ejection mechanisms are different. Also, this barrel will not fit the current recoil-operated A5 the classic Auto-5 and the modern A5 are mechanically different platforms despite sharing a name. Therefore, confirm your Auto 5 is the classic Magnum action before purchasing.
What choke system does this 12ga Browning Magnum Auto 5 Barrel with Invector Chokes use?
Standard Invector, marked “Invector” on the barrel. So the classic Magnum Auto-5 barrels marked “Invector” use the Standard Invector system. Also, this is critically different from Invector-Plus and Invector-DS — Browning explicitly warns against installing Invector-Plus tubes in a barrel marked Invector. Therefore, source only Standard Invector choke tubes for this barrel, and check the barrel marking before buying any choke tubes.
Are all Auto-5 barrels interchangeable with each other?
12ga Browning Magnum Auto 5 Barrel with Invector Chokes Within the same gauge and model, yes. So Browning states in the owner’s manual that all barrels of the same gauge and model are completely interchangeable on the Auto-5 — no special fitting required. Also, this means any Magnum 12 barrel fits any Magnum 12 action, whether it’s your original barrel or this replacement. Therefore, adding a second barrel genuinely converts your duck gun into an upland gun or vice versa, as Browning intended with this design.
Can I shoot 3-inch shells through this 12ga Browning Magnum Auto 5 Barrel with Invector Chokes?
Yes that’s specifically what the Magnum Auto-5 platform was designed for. So the Magnum action and Magnum barrel are built around 3-inch shell feeding and ejection. Also, 2-3/4-inch shells function correctly in the Magnum as well with proper friction ring adjustment. Therefore, this barrel covers the full range of standard 12 gauge loads your Magnum action was designed to handle.
Who is this 12ga Browning Magnum Auto 5 Barrel with Invector Chokes best for?
This 12ga Browning Magnum Auto 5 Barrel with Invector Chokes fits classic Magnum Auto-5 owners who need a replacement barrel or want to add a second choked barrel for different hunting applications. So if you’ve been running a fixed-choke Magnum barrel and want to switch to the flexibility of interchangeable chokes, this barrel delivers that upgrade. Also good for anyone restoring a Magnum Auto-5 to original spec or repairing a damaged original barrel.
