Sprinco Yellow AR-15 / M4 Reduced 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 reduced power carbine buffer spring is awesome for use with simunition and UTMs for Force-on-Force training. This spring is also great for competition builds with lightweight bolt carrier groups.

    I used this yellow reduced power spring with a emptied out 1oz buffer to get my 350 Legend mid length to run suppressed with subsonics. I also had opened the gas hole in the barrel to .125 and installed a adjustable gas block. The yellow spring was the last step to get it functioning properly.

    This spring my short stroking issue w/ my 300 BLk SBR when shooting 147grain – 220grain w/o a suppressor, (checked gas block alignment etc to make sure it wasn’t that), I also didn’t feel like drilling and expanding the gas port size on my ballistic advantage barrel. After buying and installing this spring, my issues ceased.
