Sprinco AR-15 Blue Buffer Spring & H2 Buffer Combo Review

About Sprinco AR-15 Blue Buffer Spring & H2 Buffer Combo

Sprinco AR-15 Blue 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. BLUE: Medium “Enhanced” Power Spring A slight increase in spring power makes this spring suited for rack grade weaponry with normal operation parameters. 16″ rifles with midlength gas systems, short barreled rifles with carbine length gas systems, etc. KAK AR-15 H2 Heavy Buffer A common and inexpensive upgrade, swapping a standard carbine buffer for a heavier H2 Buffer can be the remedy for an overgassed system and reduce the felt recoil when firing. The KAK H2 AR-15 buffer body is machined from aircraft grade almunim and hard anodized for a durable finish. Utilizing properly weighted tungsten / steel counter weights, these American Made buffers are guaranteed to perform.
