The Sprinco USA Spring Kit combines a standard-power rifle-length buffer spring with a heavy-duty 5-coil extractor spring—a practical pairing for AR platform shooters who want to refresh or fine-tune their action. The included green buffer spring delivers mil-spec load characteristics and works with A1/A2 fixed-stock rifle-length receiver extensions and standard rifle-length buffers. It's also a solid fit for VLTOR A5 intermediate-depth tubes paired with 4-inch A5 buffers, making it flexible across common AR setups.
This kit is built for shooters running lighter-recoiling rounds—think .223 Remington, 5.56 NATO, 6.8 SPC, 6.5 Grendel, or 7.62×39—where a standard-power spring keeps your rifle cycling smoothly without excessive wear. The addition of the heavy-duty 5-coil extractor spring means you're addressing reliability at the point where it matters: consistent, trouble-free case extraction. Together, these components form a dependable refresh for a rifle that's seen use, or a smart preventive upgrade for one that hasn't.
Sprinco springs are engineered with precision and manufactured to tight tolerances—you won't find the inconsistency that can creep into budget alternatives. Whether you're building a new upper or maintaining a field rifle, this kit gives you two critical wear items in one package, saving a trip back to the parts bin.
The standard-power buffer spring is designed for A1/A2 fixed-stock rifle-length receiver extensions with standard rifle-length buffers. It also works well in VLTOR A5 intermediate-depth (7.75-inch) tubes when paired with 4-inch A5 buffers.
The green spring is optimized for lighter-recoiling rounds including .223 Remington, 5.56 NATO, 6.8 SPC, 6.5 Grendel, and 7.62×39.
The kit includes a standard-power rifle-length buffer spring and a heavy-duty 5-coil extractor spring.
Yes. This kit is well-suited for replacing tired buffer and extractor springs in an existing rifle, or as a component for a new build.
