What is the SPRINCO USA - Spring Kit-STD Buffer & HD 5-Coil Bolt Extractor Spring?
Standard Power Buffer Spring. Equivalent spring load to a brand new Mil-Spec M4 Carbine Spring. This spring will perform reliably in any properly configured and maintained 5.56 Carbine if you wish to maintain the performance of a "fresh" Mil-Spec load spring without concern for replacement. This is the best choice for shooters and purists that wish to maintain the performance of most factory supplied new Mil-Spec springs, but do not wish to be concerned with frequent replacement of same or do not have the time or inclination to seek enhanced performance options. Just consider it as permanent new Mil-Spec spring.


INCLUDES
  • Standard Power Moly Plated Chrome Silicon Buffer Spring
  • Extra Power 5-Coil Chrome Silicon Bolt Carrier Extractor Spring

Great improvement! Blue may not be for you.
Ahh... the Sprinco white. You read or hear mostly about the blue ones. Well, there is a reason for this. Sometimes we want to correct a problem so bad that we can over correct it. Simple improvements that can make a great difference don't seem as sexy as the more exotic or costly options. Also, it is easy to ignore the 'low dose' version of an improvement. In a nutshell, the Sprinco white spring is a bit stiffer than even a brand new ss spring and you will notice a pleasing difference if your setup is not overgassed.
