Sprinco AR-15 Green Buffer Spring
Standard AR15/M4 buffer springs (aka “action springs”) are wear items which must be replaced regularly in order for AR-15s to operate reliably, with conservative replacement taking place every 5000 rounds. Sprinco action springs in comparison, are over engineered and will last over 50,000 cycles.
Sprinco Chrome Silicon buffer springs are heat treated, stress relieved, and dual-stage shot peened in separate post winding treatments. Sprinco also treats each spring with a proprietary, deep-penetrating, re-micronized (to .3 Micron particle size), inhibited, Molybdenum-Disulfide (MoS2) formulation to eliminate 90% of all mechanical wear on the spring: this is why Sprinco springs do not produce the spring sound during shooting which is common with standard action springs.

In addition to use in 5.56 Fixed Stock Rifles, the “Green Spring” is just the ticket for use in the VLTOR A-5 Stock System using their standard weight (5.2 Oz.) buffer for maximum versatility with almost any 5.56 upper barrel configuration, both with or without a “can”
