Promag SKS Mag: Durable Polymer 7.62×39 Firearm Accessory

PROMAG SKS

Overview: What the PROMAG SKS Brings to the Table

The PROMAG SKS is built around the SKSA5 configuration: a 20-round magazine designed specifically for SKS rifles and carbines chambered in 7.62×39. Unlike stamped steel or aluminum options, the magazine body and follower use a proprietary DuPont Zytel-based polymer, chosen for durability, abrasion resistance, and reduced weight. At a price point of $16.19, this magazine provides an affordable way to modernize an SKS without breaking the bank.

Materials and Build: Polymer Advantage

Promag used a DuPont Zytel-based polymer for both the magazine body and follower. Zytel is a well-known engineering plastic with a track record in high-stress components. Benefits for field use include:

Durability and Longevity

Zytel resists impact and cracking better than many cheaper polymers. The polymer follower reduces friction and is less prone to corrosion compared to metal followers, which helps maintain reliable feeding over extended service life.

Weight and Handling

A polymer magazine is lighter than steel, improving balance when carried in multiple mags. The textured body and polymer construction make it comfortable to manipulate in gloves or cold weather.

Compatibility and Fitment Considerations

The PROMAG SKS is designed for SKS rifles and carbines in 7.62×39, but the product description includes a critical note about fitment: due to variability in magwell dimensions across SKS manufacturers and conversions, this magazine may require handfitting or may not be suitable for every individual firearm. Experienced gunsmiths and armorers will tell you that SKS receivers and aftermarket conversions vary widely—so expect to verify compatibility before relying on it for duty use.

Practical Steps for Owners

If you plan to use the PROMAG SKS on a converted SKS or an aftermarket receiver, follow these recommendations:

–

Test-fit the magazine without live ammunition first to check latch engagement and seating depth.

–

Inspect the feed lips and follower for smooth movement; a light polishing or deburring may be needed if a conversion altered the magwell edges.

–

If the mag requires modification, consult a qualified gunsmith to avoid compromising safety or function.

7.62×39: Cartridge Benefits and Typical Uses

The PROMAG SKS is built for the 7.62×39 cartridge. Key characteristics of this caliber include manageable recoil, good barrier penetration, and economical ammunition availability. Common applications:

Range and Training

7.62×39 remains popular for training because rounds are relatively affordable compared to many rifle calibers. A 20rd magazine lets shooters maintain longer strings of fire without repeated reloads, improving drills and marksmanship practice.

Field and Utility Use

For hunters and field users in regions where SKS rifles are common, the 7.62×39 performs well on medium-sized game at appropriate distances. The PROMAG SKS provides quick reload capability for practical field tasks and controlled follow-up shots.

Performance Expectations and Maintenance

Owners should expect reliable feeding from a well-fit PROMAG SKS when paired with a properly maintained rifle. Polymer followers tend to reduce feeding hang-ups caused by rust or debris buildup. Regular maintenance tips:

–

Keep the magazine clean of grit and unburnt powder; a soft brush and compressed air work well.

–

Inspect the feed lips and follower for wear; polymer degrades slowly but can show signs of wear after heavy use.

–

Store magazines unloaded for long-term storage to relieve spring tension.
