Customer Feedback
“I swapped the factory spring for the ARMA SPEC Stealth Spring and the difference is night and day—my follow‑up shots are faster and the recoil feels much smoother.” – John D., Competitive Shooter

Frequently Asked Questions (FAQ)
- Do I need a new buffer when installing this spring?
- While the spring works with most standard buffers, we recommend pairing it with a high‑capacity buffer for optimal performance in high‑pressure calibers.
- Can I use this spring in a standard 5.56 mm rifle?
- Yes, the spring is compatible with 5.56 mm platforms, but it shines when handling the increased energy of big‑bore loads.
- Is the black coating durable?
- Absolutely. The stealth coating is engineered to resist scratches, abrasion, and corrosion, maintaining its appearance and performance over time.
