Sprinco White AR-15 / M4 Standard 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 standard power carbine buffer spring is the choice for when you’re looking for a 1-to-1 replacement in power, but upgrade in longevity.

Super fast shipping, great price, and a free Ramen meal before I installed my new spring. Rooftop Defense is the best.

The Sweatshop scared the hell out of me with how fast they shipped my springs which are in perfect condition. Now these FRTs will sing. My experience could not have been any better. I will be a repeat customer. I appreciated the note and the ramen came in handy too.
