Sprinco 30 Round AR-15 Magazine 17-7 SST Flat Wire Spring
The Sprinco 30 Round AR-15 Magazine Spring upgrades an old worn-out spring to a flat wire design to keep your magazine running like new. These springs feature 17-7 stainless steel MIL-SPEC construction for long-lasting durability and reliable performance. Unlike round wire springs, the flat wire design prevents buckling to ensure a uniform feed rate. Built for strength, the flat wire spring is tough enough to keep magazines fully loaded for long periods without experiencing spring fatigue. These drop-in replacement springs are compatible with most 30-round magazine brands and followers, providing reliable function for many years. Bring life back to your magazines and keep them functioning properly with the Sprinco 30 Round AR-15 Magazine Flat Wire Spring.
Note: These flat wire springs will not work with Brownells USGI tan followers, ETS magazines, and some HK followers.
