Sprinco Blue AR-15 / M4 Enhanced 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 enhanced buffer spring has been proven to work well with setups with midlength gas systems and short-barreled rifles with carbine length gas systems.

Never had an issue with these springs. They are a great upgrade for most anything with carbine gas and an 13.7+ inch barrel. And Rooftop stocks them all with immediate shipping.
