Sprinco buffer springs are made from ASTM Grade A877 certified valve quality chrome silicon wirestock. They are heat treated, stress relieved and dual stage shot-peened post winding and uses impregnation/plating with re-micronized Molybdenum Disulfide formulation. These springs offer greater resistance to heat induced performance degradation and improves cyclic operation and consistency.
Sprinco uses a color code is used to differentiate spring rates depending on your application.
BLUE - Enhanced Power Buffer Spring. The design loads of the Blue spring are approximately 15% greater than the White spring for one of the considered Load Constants in the spring design. Sprinco was encouraged to manufacture the Blue spring by Mike Pannone of CTT Solutions, who modified the Red springs and recommended that Sprinco offer a spring with the loads of the Blue spring to address the high performance demands of other specimen platforms. While contemporary internet forum lore leans towards the use of the Blue spring with an H2 or ST-T2 buffer for 14.5 - 16” ML carbines, nothing is set in stone due to the vast range of gas port values in the wild that have come into play. Color Coded BLUE.
