Availability: In Stock
The Spike's Tactical Carbine Buffer Spring is a mil-spec replacement component built from 17-7 stainless steel with an electro-polished finish. Whether you're assembling an AR-15 carbine from a stripped lower, upgrading an existing rifle, or keeping a spare on the shelf, this spring delivers the same reliability found in Spike's factory-assembled rifles. The electro-polished 17-7 stainless construction resists corrosion better than standard carbon steel and provides a refined, durable feel—important when you're counting on smooth, consistent bolt carrier travel during practice, competition, or hunting.
Buffer springs wear and lose tension over time, especially on rifles that see regular use. A fresh spring restores proper bolt carrier velocity and helps maintain the reliability of your recoil system. Spike's Tactical springs are manufactured to mil-spec tolerances, meaning they'll integrate seamlessly with standard buffer tubes and carriers across the AR platform.
This is a no-frills, no-marketing component—exactly what you need for a dependable build or maintenance refresh.

Yes, this carbine buffer spring is designed as a drop-in replacement for standard AR-15 carbine systems. If your current spring has lost tension or shows damage, this will restore proper bolt carrier function.
