FN Auto-5 Standardweight 12 Gauge Semi-Auto Shotgun, Belgian Pre-War, 26-Inch, Poly-Choke, Custom White-Line Pad
This Belgian-made FN Auto-5 Standardweight was manufactured in 1929 and combines classic pre-war craftsmanship with period-correct upgrades. The long-recoil action, forged steel receiver, and distinctive hump-back profile make it immediately recognizable to collectors, while the factory rust-blue finish, checkered walnut stock, and Belgian proof marks confirm its authenticity. A Poly-Choke adjustable muzzle device and a White-Line ventilated recoil pad add functional versatility and showcase mid-century customization trends.

What’s Included
- FN Auto-5 Standardweight 12 Gauge shotgun with installed Poly-Choke and White-Line recoil pad
The heart of this shotgun is its John M. Browning-designed long-recoil action, tuned for 2 ¾-inch 12 gauge loads. The action provides smooth cycling and includes the Auto-5’s signature magazine cut-off, allowing quick switching between shells without unloading the magazine.
Its 26-inch plain carbon-steel barrel wears the period-installed Poly-Choke, giving the shooter on-the-fly choke adjustment from open to tight patterns—an upgrade favored by hunters and clay shooters of the era.
The rust-blue finish on the receiver and barrel retains consistent color, complemented by walnut furniture that features sharp checkering on the round-knob pistol grip and fore-end. A 14-inch length of pull culminates in a White-Line ventilated rubber pad, a popular aftermarket addition that softens recoil and lengthens the stock for modern ergonomics.
Belgian crowned PV proofs, star-over-letter inspector marks, and the FN cartouche underscore its Liège heritage. Combined with its early production date and tasteful period accessories, this Auto-5 offers both shooting utility and collectible appeal.
