ProMag SKSA3 40-Round 7.62x39 SKS Magazine Black Polymer

The ProMag SKSA3 transforms the SKS rifle's limited capacity into a high-volume platform with its 40-round detachable magazine. This aftermarket upgrade replaces the standard 10-round fixed magazine, providing tactical shooters and hunters with extended firepower without frequent reloading interruptions.

What Makes This Different

Unlike steel magazines that add significant weight, the SKSA3 utilizes DuPont Zytel polymer construction that maintains structural integrity while reducing overall rifle weight. The magazine feeds reliably with standard 7.62x39 ammunition and features reinforced feed lips that resist deformation under stress. Drop-free release ensures rapid magazine changes during competitive shooting or extended range sessions.

Key Features

• 40-round capacity increases firepower 4x over standard SKS fixed magazine
• DuPont Zytel polymer construction resists impact damage and environmental stress
• Reinforced steel feed lips prevent ammunition misfeeds and jams
• Drop-free design enables rapid tactical reloads
• Anti-tilt follower maintains consistent cartridge presentation
• Textured exterior provides secure grip during manipulation
• Compatible with all standard SKS rifle variants

Field testing demonstrates consistent feeding across various ammunition weights from 123-grain to 154-grain projectiles. The polymer body withstands temperature extremes from -20°F to 140°F without cracking or warping. Competition shooters report improved stage times due to reduced reload frequency, while hunters appreciate the extended capacity for predator control applications.
