Sprinco Hot White AR-15 / M4 Intermediate Power Carbine Buffer Spring
Sprinco AR-15 buffer springs are made from high quality Chrome Silicon wire stock which is used in a variety of applications from Formula One to motor valve springs which can see up to 15,000,000 compression cycles in a single race. This makes it the perfect choice for a carbine which will see far less cycles than that over it’s lifetime. In order for this carbine buffer spring to retain its strength, Sprinco heat treats, shot peens, and treats each spring with a proprietary formula that retains spring efficiency for as long as you have your rifle. Sprinco buffer springs are a great option to improve the long-term reliability of your AR-15.
This intermediate power carbine buffer spring is slightly more powerful than a standard carbine spring. Sprinco’s testing has found that these are great for rifles with midlength gas systems.

This was the sweet spot. Had a sprinco blue and it was slowing it down a bit too much. Nice middle ground for something stiffer than standard but not over the top
