Frequently Asked Questions
- Is the AR0072A compatible with a 14.5‑inch barrel?
- Yes, the AR0072A is specifically designed for carbine‑length builds, including both 10‑inch and 14.5‑inch barrel configurations.
- Can I use this spring with a standard 1.5‑inch buffer?
- Absolutely. The AR0072A works with standard 1.5‑inch buffers; however, pairing it with a heavier buffer can further reduce recoil for certain applications.
- What makes this recoil spring different from OEM parts?
- Rock River Arms uses premium spring steel and a proprietary heat‑treatment process that yields a spring with higher tensile strength and consistent coil tension, resulting in superior reliability over many factory‑grade springs.
