Sprinco Recoil Solution Buffer Spring

• Red Extra Power Buffer Spring. This was our first AR buffer spring solution that we were tasked to design back in 2006 for a Force Modernization Team to specifically address spring-related M4 carbine reliability function issues for operating challenges in the Eastern Asia Theatre. The design loads of the Red spring are approximately 25% greater than the White spring for one of the considered Load Constants in the spring design. Refer to provided tuning procedure reference documents prior to calling for recommendations for use. The Red spring is commonly used in 9mm, 6.8 SPC, 6.5 Grendel, .450 BM, .450 SOCOM, .500 Beowulf, and Colt LE6920’s specimen carbines, but certain specimen guns can deviate from the norm depending upon port values and the power factor of your chosen ammunition loads. Color

  • NOTES: The RED spring is appropriate for moderately gassed .308 / 6.5 CM / .260 Rem heavier caliber carbine platforms using AR-10 / SR-25 Pattern (Armalite, LMT, LaRue, KA.C, etc. receiver extensions and 3.25” carbine buffers. NOT for use in “DPMS Pattern”.308 Carbines using standard 7" deep M4 extension tubes and short, 2.5” buffers. (Use our "ORANGE” Spring" for that specific platform approach application.)

• Orange Extra Extra Power Buffer Spring. The Orange spring is much stouter than the Red spring. The Orange buffer spring was originally engineered for the demands presented by.308 / 6.5 CM / .260 Rem, etc., heavy BCG carbine DPMS Pattern applications using standard 7" Depth M4 extension tubes and short 2.5" buffers (Including aftermarket "heavy buffers") in robustly gassed 16” - 18” ML gas carbine platforms, but has been proven to be a requirement for tuning over gassed carbines of any equivalent heavy calibers in AR-10 pattern tubes with 3.25" buffers or lesser calibers (5.56, etc.). 

  • Don't clip coils from any of our other buffer springs in order to yield a lighter spring load for DPMS pattern applications. Doing so will result in an unknown spring load and might damage the gun.

  • NOTES: If your build is yielding a solid 1:30 to 2:00 O'clock ejection trajectory, then start with an Orange spring and tune it with the buffer weight. Empirical evidence has shown a heavier spring and lighter buffer produces better performance than a lighter spring and heavier buffer.

• White 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.

CONSTRUCTION SPECS: CARBINE & RIFLE BUFFER SPRINGS

• ASTM Grade A877 Certified Valve Quality Chrome silicon Wirestock
• Heat Treated, Stress Relieved and Dual Stage Shot-Peened post winding (Our springs really ARE shot-peened)
• Impregnation / Plating with Re-Micronized Molybdenum Disulfide formulation
• Hard plastic tube packaging for protected transport and easy storage (Tubes make great storage compartments for all sorts of gear)
• Optional Cryogenic Processing Available (Select Item 26001)

ADVANTAGES:

• Increased "lock time" for faster sight recovery and platform stability
• Consistent spring pressure throughout the duty cycle of the spring, resulting in fewer malfunctions related to spring operation (Especially Type III malfunctions)
• Improved & consistent cyclic operation. Spring will not change performance for many hundreds of thousands of rounds
• Greater resistance to heat induced performance degradation
• Reduced cyclic rate with Enhanced or Extra Power springs and reduce / eliminate bolt bounce with optimal spring / buffer weight selection
• Reduced operating cost as replacement springs are not needed during the life of your upper receiver assembly. Less downtime and fewer trips to the armorer for spring replacement, in fact, this will most likely be the only buffer spring you will ever need for the duty cycle of your carbine or rifle!
• Correct spring selection works reliably, consistently, and virtually indefinitely in all properly built and maintained AR platforms
