.223 Rem / 5.56 NATO compatibility for modern versatility
Chambered in .223 Remington and 5.56x45mm NATO (rifle and chamber dependent), these cartridges are popular for everything from varmint hunting and predator control (where legal) to training, range work, and general-purpose bolt rifle use. A dedicated magazine built for this cartridge family helps support:
Smooth feeding and consistent cartridge presentation
Reliable cycling during repeated bolt manipulation
Practical performance for hunting and range sessions
Always confirm your rifle’s chambering specifications and ammunition recommendations, especially when using .223 Rem vs. 5.56 NATO.
5-round capacity: ideal for hunting and practical field use
A 5-round magazine is the perfect balance for many bolt-action shooters—compact, lightweight, and practical. It’s especially popular for:
Hunting where lower-capacity magazines are preferred or required
Maintaining a sleek profile for carry and field handling
Quick loading and unloading at the range
A reliable spare magazine that doesn’t add bulk to your kit
Whether you’re walking the field or working from a bench, 5 rounds is a clean, efficient capacity that keeps your rifle setup streamlined.
Black polymer construction: lightweight, durable, and weather-friendly
This magazine is constructed from black polymer, offering a practical blend of durability and weight savings. Polymer magazines are often preferred by hunters and field shooters because they:
Resist corrosion in wet or humid conditions
Stay lightweight in your pack or pocket
Hold up well to common bumps and handling
Are easy to clean and maintain
The black finish keeps the look discreet and matches most Sauer rifle configurations for a clean, cohesive setup.
Perfect for spares, replacements, and range-day efficiency
Even the best magazines can wear over time, and having a spare is simply smart ownership. The Sauer S10507 magazine is ideal for:
Replacing a worn or damaged magazine
Keeping a spare for hunting trips and travel
Building a multi-mag setup for smoother range sessions
Maintaining a consistent rotation of magazines to reduce wear on any single mag
For Sauer 100/101/M18 owners, having an extra correct-fit magazine on hand is one of the easiest ways to improve convenience and confidence in the field.

Reliable performance under normal use conditions
Better long-term compatibility with the rifle’s magazine well and latch system
