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 in an M-4 Carbine without a measureable deterioration in power, performance or reliability.
The enhanced power spring is for weapons that cylce properly with a standard power spring and provides the long service life and sustained reliability of a high quality spring. A standard weight spring is a good choice is you like the way your rifle cycles but you just want a higher quality spring that will last longer and give you excellent reliability and consistency over a long service life. Or if you are building a new rifle and don't perceive the need for an extra power spring but just want the best spring available, this is the one to use. Many rifle manufacturers cut corners on the quality of springs they use in their rifles to save money. But some of the manufacturers of the highest quality AR rifles are starting to realize the benefits of using top of the line springs like these. Don't cut corners with cheap springs, get the best and you will be glad you did.
This spring fits any full length / fixed stock AR-15 or M-16 series rifle.
