Sprinco .308 Extra Power Buffer Spring - For Collapsible Stocks with 2.5" buffer (Orange Spring)
This Chrome Silicon recoil spring is made by Sprinco USA to the highest quality standards available. It is stress relieved for long service life and Moly-Plated for corrosion resistance. These springs last for an incredibly long time and do not lose their strength. Test samples of these springs have been tested for over 100,000 rounds without a measureable deterioration in power, performance or reliability.
The Extra Power Buffer Spring is designed for .308 AR Carbine Platforms that use the standard 7" depth M4 buffer tubes and the short 2.5" .308 buffer. Such as DPMS, CMMG, Bushmaster (post 2010), Mega, SA Defense, Colt 901 and many others. The extra power slows the bolt carrier's rearward travel and chambers the next round with more authority.
