Factory Sauer 505 Barrel – Perfect Fit, Maximum Confidence
This is a genuine Sauer 505 barrel, engineered to integrate seamlessly with the 505 action and stock system:
Designed specifically for the Sauer 505 platform
Maintains factory-level fit, headspace, and alignment when properly installed
Ideal for upgrading, replacing a worn barrel, or adding a new caliber option to a multi-barrel 505 system
Instead of relying on third-party parts, you get OEM compatibility and quality, which is critical when working with a high-performance magnum cartridge.
.300 Winchester Magnum – Long-Range Power & Versatility
Chambered in .300 Win Mag, this Sauer 505 barrel is purpose-built for serious big game and long-distance shooting:
Excellent for elk, moose, large deer, and similar big game at extended ranges
Widely supported with factory loads optimized for long-range hunting and precision shooting
Delivers flat trajectories, strong energy retention, and dependable terminal performance when paired with quality ammunition
If you want your Sauer 505 to reach confidently across canyons, clear-cuts, or open tundra, a 300 Win Mag barrel is an outstanding choice.
Optimized Length & Contour for Field Use
The Sauer 505 300 Win Mag barrel is engineered to balance accuracy, velocity, and carry comfort:
Length and contour are tuned for stability and harmonics, helping support consistent groups at distance
Magnum-ready profile designed to handle the pressures and recoil of .300 Winchester Magnum
Built for real hunting conditions—steady from shooting sticks, prone, or off a backpack rest
The result is a barrel that’s at home both on the range and on demanding hunts, where first-round hits matter most.
9/16"x24 Threaded Muzzle – Ready for Brakes & Suppressors
A major advantage of this barrel is its 9/16"x24 threaded muzzle, giving you modern muzzle device flexibility:
Accepts compatible muzzle brakes, flash hiders, and suppressor adapters
A quality brake can significantly reduce felt recoil and muzzle rise, helping you spot impacts and stay on target
Thread protector (typically included with many threaded barrels, or easily sourced) helps keep threads safe when no device is installed
If you’ve considered taming magnum recoil with a brake or going suppressed (where legal), this 9/16x24 barrel is ready from day one.
Premium Steel Construction & Matte Finish
Built for demanding hunts and tough conditions, the Sauer 505 300 Win Mag barrel uses high-grade steel and a field-ready finish:
Precision-machined steel for consistent bore geometry and long service life
Matte exterior finish helps reduce glare, keeping your rifle low-profile in bright sunlight or snowy terrain
Corrosion-resistant treatment (typical of modern Sauer barrels) supports reliability in wet, cold, and harsh weather
From rain-soaked forests to wind-swept ridges, this barrel is designed to perform and endure.
Easy Caliber Conversion for the Modular Sauer 505
One of the biggest benefits of the Sauer 505 platform is its modularity, and this barrel unlocks that potential:
Turn an existing 505 rifle into a long-range .300 Win Mag performer simply by adding this barrel (and appropriate bolt/mag components as required by Sauer’s system)
Create a multi-caliber setup: run a lighter-recoiling caliber for local hunts and switch to 300 Win Mag for your big trips or open-country hunts
Ideal for hunters who travel or chase different game in varying environments and want one familiar rifle system with multiple barrel options
Instead of buying multiple complete rifles, you can build a versatile 505 platform centered around this 300 Win Mag barrel.
Ideal for Big Game, Mountain Hunts & Long-Range Shooting
Outfitting your Sauer 505 with this 300 Win Mag 9/16"x24 barrel makes perfect sense if you:
Hunt elk, moose, red stag, or large plains game where longer shots are common
Shoot across canyons or wide fields and want a cartridge that carries energy far downrange
Prefer a single rifle system that can be tuned with different barrels for different seasons and species
With the right optics and stock setup, this barrel can transform your 505 into a high-confidence long-range hunting machine.
