657780252039 Intermediate Power Buffer Spring. The Hot White spring came to life as an accident that turned out to be a valuable solution for certain platforms. Sprinco did a production run of White springs where the loads came in perfectly between the design loads of the White and Blue spring, so they sat them aside and did another run of White springs to the proper load specifications. When Sprinco had some calls from customers wishing for a spring that was in between the performance of a White or Blue spring, they had them try out the discarded springs on a trial basis, and they turned out to be perfect for their needs, thus, the evolution of the Hot White spring for tuning purposes. If you are among those who are advocates of using Mil-Spec carbine springs rather than tuning to perfection, this is also a good choice in the vast majority of instances to enhance performance.

Description:

Enhance your firearm's performance with the M4 Carbine CS Intermediate Spring Kits!

The M4 Carbine CS Intermediate Spring Kits by SPRINCO USA feature an innovative design that bridges the gap between standard White and Blue buffer springs.

Product Description

The Intermediate Power Buffer Spring was born from a fortunate accident, leading to a valuable solution for various platforms. During a production run of White springs, SPRINCO discovered that the loads fell perfectly between the designed specifications of the White and Blue springs. These springs were initially set aside, but upon customer requests for a spring that offered a balance between the two, they were put to the test on a trial basis.

The result? A perfect fit for those seeking enhanced performance without sacrificing reliability. This evolution gave rise to the Hot White spring, which is ideal for tuning purposes.

If you prefer using Mil-Spec carbine springs rather than fine-tuning for optimal performance, the Hot White spring is an excellent choice in most situations, ensuring your firearm operates at its best.

  • Intermediate power for versatile applications
  • Perfect for those who need a balance between White and Blue springs
  • Enhances performance while maintaining reliability

Upgrade your setup today with the M4 Carbine CS Intermediate Spring Kits from SPRINCO USA, available at Brownells UK!
