Tactical Springs (Sprinco) .308 Carbine Extra Power Buffer Spring - Orange


Sprinco AR-10 carbine 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 intermediate power carbine buffer spring is a great option to improve the long-term reliability of your AR-308.

"ORANGE Spring": The ONLY specifically engineered EXTRA POWER Buffer Spring for .308 Carbine Platforms using standard 7" Depth M4 extension tubes and .308 short 2.5" buffers (Including aftermarket "heavy buffers.") You cannot clip coils from any other commercially available buffer spring to yield the proper spring loads for this application, especially in heavily gassed .308 carbine platforms. We started from scratch on this design to provide Operators with a viable alternative to existing OEM and aftermarket offerings. Platforms known to exist using this approach include DPMS, Bushmaster (Post 2010), Remington, CMMG, Mega, SA Defense, Colt 901, Rock River Arms and many others.
