The Sprinco USA Spring Kit pairs an extra-power buffer spring with a 5-coil extractor spring to address cycling issues in AR-platform rifles that run hot or demand stiffer spring rates. The orange XXP buffer spring is significantly heavier-duty than Sprinco's standard red spring, making it the choice for shooters tuning over-gassed rifles or running heavier calibers where standard springs cause reliability problems or excessive wear.
This kit was originally developed to handle the demands of .308, 6.5 Creedmoor, and .260 Remington in heavy bolt-carrier-group carbine setups—especially DPMS-pattern AR-10s with 3.25" buffers or short 2.5" buffers paired with standard 7" extension tubes. But the XXP spring has proven itself across the board: if your rifle is running too fast, short-stroking, or battering itself to pieces, this spring kit tackles the root problem without forcing a complete upper rebuild.
Pair this with the included 5-coil extractor spring to dial in both directions of the cycling equation. Whether you're running a 16" to 18" medium-length-gas carbine in a heavy caliber, an over-gassed 5.56 build, or an AR-10 that refuses to settle down, the XXP buffer spring delivers the platform control you need. Drop-in installation—no gunsmithing required.
Yes. While originally designed for heavy-caliber AR-10 applications, the XXP spring has proven effective in over-gassed AR-15s of any caliber, including 5.56 and intermediate cartridges.
The orange XXP spring is substantially heavier-duty and stiffer. It's built for rifles running hot or heavy bolt carriers where a standard spring won't slow the action enough.
No. Both the buffer spring and extractor spring are direct drop-in components that require no modifications or special tools.
The kit was engineered for .308, 6.5 Creedmoor, and .260 Remington in AR-10 platforms, but it works across any caliber where your rifle is over-gassed or cycling too fast.
