Frequently Asked Questions
Will this flat wire spring work with my existing buffer and carbine buffer tube?
Yes. The Strike Industries SI-AR-FWS-C is designed as a direct drop-in replacement for the standard round-wire recoil spring found in mil-spec AR carbine buffer tubes. It is compatible with standard carbine-length receiver extensions and works with most AR-15 buffers without any modifications to your existing setup.
What are the advantages of a flat wire spring over a standard round wire spring?
Flat wire springs offer a more consistent compression rate throughout the entire stroke, resulting in smoother cycling and reduced felt recoil. The flat wire geometry also allows the spring to compress more efficiently within the buffer tube, reducing spring bind and noise. Additionally, flat wire springs typically have a significantly longer service life compared to traditional round wire coil springs.
Does this spring require any special tools or gunsmithing to install?
No special tools are required. Installation is straightforward — simply remove your existing buffer and recoil spring from the receiver extension, insert the Strike Industries flat wire spring along with your buffer, and reassemble. The process takes only a few minutes and is well within the capability of any AR-15 owner comfortable with basic field-stripping.
