WHAT MAKES OUR SPRINGS UNIQUE?
All of our springs are constructed from Certified Chrome Silicon wirestock to ISO 9001:2008 quality standards to withstand extreme heat and highly cyclic rate. The certification rating ensures a consistency in the parent material of 95%, which translates to repeatable consistency in performance & function. Certified Valve Quality Chrome Silicon wire is used in very high stress applications such as, NASCAR, Formula One, Moto GP & Pro Stock racing motor valve springs. It is not uncommon in some of these applications for valve springs to see 15,000,000 compression cycles in one race. It is this extraordinary capability that makes Chrome Silicon wire the obvious choice in our spring production vs. music wire or 17-7 PH used in OEM springs and by most aftermarket competitors. In addition, all of our Chrome Silicon buffer springs are heat treated, stress relieved, and dual-stage shot peened in separate post winding treatments. We also treat 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. The combination of materials & processes result in a loss of no more than 5% in spring efficiency. The minimum anticipated duty cycles of our buffer spring designs are in excess of 1,500,000 cycles.
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
- Optional Cryogenic Processing available upon request
Shortened “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.
SPRINCO BUFFER (ACTION) SPRINGS
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.
Select from the following options:
- RED: AR15 Extra Power Spring
The option with the most spring tension, this spring is suited for rifles and carbines with excessive bolt speeds. This spring is suitable for 14.5″/16″ uppers with carbine length gas systems (which are typically over gassed), all suppressed rifles, piston operated rifles, and 9mm conversions
- BLUE: AR15 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.
- WHITE: AR15 Standard “Regular” Power Spring
Equivalent spring power of a “fresh” AR15/M4 carbine action spring, this spring is for users who do not want to dabble with improving performance with extra power springs, but do not want to frequently replace their action springs as well
Red/White: AR15 “WHITE HOT” INTERMEDIATE Power Buffer Spring, Falls between the standard power (WHITE) and the enhanced power (BLUE) Color Coded WHITE / RED.
- YELLOW: AR15 Reduced Power Spring
Useful for undergassed rifles, such as some midlength gas rifles or “Dissipator” builds which is apparent with rifles that short stroke or have weak ejection patterns
AR-15 Rifle / Fixed Stock Spring
- GREEN: AR15 Rifle Length Spring
In addition to use in 5.56 Fixed Stock Rifles (A2 Stocks, Magpul PRS) 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”
AR-10/SR-25 pattern rifles
- ORANGE: .308 Extra Power Carbine Spring (DPMS/SR-25 Pattern)
The ONLY spring specifically engineered for .308 Carbine Platforms that use 7″ Depth M4 extension tubes and short 2.5″ Buffers (including aftermarket “heavy buffers”), this list includes: Aero Precision, Matrix Arms, DPMS, Bushmaster (Post 2010), Remington, CMMG, Mega, SA Defense, Colt 901, Rock River Arms, and more
