SPRINCO USA
White Standard Power Carbine Buffer Spring
A standard power carbine buffer spring loaded to match a brand new mil-spec M4 carbine spring. Color coded white.
A Permanently New Mil-Spec Spring
A factory carbine spring works well when it is new. The problem is that it does not stay new, and most people never track how many rounds are on one.
The White is loaded to that same fresh mil-spec spec and built to hold it. It performs reliably in any properly configured and maintained 5.56 carbine, without the replacement cycle.
This is the choice for shooters who want mil-spec performance kept mil-spec, rather than tuning for something else.
Which Sprinco Spring Do You Need?
Sprinco color codes every spring so you can identify what is in a rifle without pulling it apart. For AR-15 carbine buffer tubes, lightest to heaviest:
- Yellow, reduced power — roughly 20% lighter than White, for Simunition, SRTA, and lightweight competition rifles
- White, standard power — this one, the load of a brand new mil-spec M4 spring
- Hot White, intermediate power — between White and Blue
- Blue, enhanced power — roughly 15% greater than White
- Red, extra power — roughly 25% greater than White, for over gassed carbines and heavier cartridges
- Orange, extra extra power — stouter than Red, for DPMS pattern .308 carbines
For a rifle length tube, including the VLTOR A5, use the Green rifle length spring.
The Wire
Sprinco springs are made from chrome silicon wire stock, the same material used in Formula One and motor valve springs, where a spring may see up to 15 million compression cycles in a single race. A carbine will see a fraction of that over its life.
Each spring is heat treated, shot peened, and treated with a proprietary formula intended to hold spring rate over time.
