When you depend on a rifle for defense or duty use, magazine reliability and material quality are non‑negotiable. A durable, low‑fatigue magazine reduces malfunctions and keeps reloads predictable under stress.

PROMAG FN SCAR 17 is a 20‑round replacement magazine engineered specifically for Scar 17 and Scar Heavy platforms. Constructed from Technapolymer — an advanced proprietary carbon fiber glass‑fill polymer — it balances weight savings with impact resistance. The magazine uses a heat‑treated chrome and silicone spring designed for extended reliability and a lower spring fatigue rate, making it a practical choice for high‑round‑count training or duty carry.

The PROMAG FN SCAR 17 fits Scar 17 and Scar Heavy models without the need for modification. For operators running heavy drills or hunters who demand quick follow‑ups, the 20‑round capacity provides a balance between firepower and maneuverability. At a street price of $21.99, it’s an economical way to expand capacity or keep spares in your range bag.

Materials and spring design that matter

Technapolymer body

Technapolymer provides a robust outer shell resistant to cracking, temperature shifts, and impact — important traits for field gear. Carbon fiber glass fill improves stiffness without adding the weight of metal magazines.

Heat‑treated chrome & silicone spring

The magazine uses a heat‑treated chrome and silicone spring to resist corrosion and preserve spring life. That lower spring fatigue rate translates to more consistent feeding across cycles, which reduces malfunctions during prolonged use.

For deployable setups or training racks, having magazines that maintain spring tension over time is a force multiplier. View product details and pricing by following the link — it leads straight to our product page and the retailer purchase flow.
