Why we like these:
One of the quickest and easiest ways to tune the performance of your AR-15 is to swap out the buffer and buffer spring. Sprinco makes industry leading buffer springs, and has a variety of options depending on the spring power you are looking for.
Official Description:
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. The Sprinco carbine buffer spring is a great option to improve the long-term reliability of your AR-15.
