Sprinco AR10 Extra Power Action Spring - Orange
Standard AR15/M4 buffer springs (aka "action springs") are wear items which must be replaced regularly in order for AR-15s to operate reliably, with conservative replacement taking place every 5000 rounds. Sprinco action springs in comparison, are over engineered and will last over 500,000 cycles.
I was first clued in to these springs by former US Marine and US Army Special Forces solider and trainer Mike Pannone, and have run one spring on my main rifle since 2008. Despite a strong dry firing and live fire firing schedule (10-15K annually) this spring is still going strong! We at Weapon Outfitters fully endorse the Sprinco spring's performance and longevity.
Extra Power for .308 Carbine (color coded ORANGE): The ONLY specifically engineered EXTRA POWER Buffer Spring for .308 Carbine Platforms using standard 7" Depth M4 extension tubes and .308 short "stubby" buffers (Including aftermarket "heavy buffers.") You cannot clip coils from any other commercially buffer spring to yield the proper spring loads for this application, especially in heavily gassed .308 carbine platforms.
