The Sprinco 30-Round AR-15 Flat Wire Magazine Spring (Sprinco part no. 24530) is a replacement spring for 30-round AR-15 magazines. Instead of round wire, it uses a flat wire coil that Sprinco says does not buckle, which keeps the feed rate uniform from the first round to the last. The wire is 17-7 stainless, moly plated and cryogenically processed. It is a straightforward fix for a worn magazine that has started to feed sluggishly, and a sensible upgrade for the mags you depend on at the range or in a match bag.

Key Specifications

• Magazine fit is 30-round AR-15 magazines, the capacity the spring is sized and wound for.
• The coil is flat wire, which Sprinco says does not buckle the way round wire springs can, so the feed rate stays uniform.
• Wire construction is 17-7 stainless, mil-spec, a spring-grade alloy chosen for strength and corrosion resistance.
• The spring is moly plated, a coating that cuts friction as the coils move against each other and the magazine body.
• It is cryogenically processed, a treatment Sprinco applies to the finished spring.
• The listing is for one spring, enough to rebuild a single magazine.
• Sprinco states it fits most magazine bodies and anti-tilt followers, including USGI, Magpul, Lancer, Hexmag and Orlite.
• Sprinco lists Brownells USGI tan followers, ETS mags and some HK followers as the exceptions to that fit.
• Sprinco says the spring cannot be over-compressed, so a magazine can be stored at full capacity without spring fatigue.
