Product Description
The Strike Industries (SI) Carbine Flat Wire Spring is a simple, affordable upgrade for AR-platform rifles using a carbine buffer system. Designed to smooth the shooting cycle and extend service life beyond standard springs, this flat wire spring helps enhance cycling reliability with increased bolt load and reduced compression force. Each spring is cryogenically stress-relieved for greater consistency, longer spring life, and improved resilience during high cyclic rates—making it a smart option for replacing a worn buffer spring or finishing a new build.
Product Highlights
- Cryo-cycled 17-7 PH steel construction for strength, reliability, and longevity
- Flat wire design helps smooth cycling and extend spring service life over stock springs
- Decreased harmonics help reduce system vibration for faster follow-up shots
- Increased bolt load supports more positive feeding and reliable cycling
- Helps reduce the distracting AR “twang” commonly associated with standard springs
