Tactical Springs (Sprinco) AR Carbine and Rifle Buffer Springs (Single Spring)
Tactical Springs LLC 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 Tactical Springs LLC's spring production vs. music wire or 17-7 PH used in OEM springs and by most aftermarket competitors. In addition, all of Tactical Springs LLC's Chrome Silicon springs are heat treated, stress relieved, and shot peened in separate post winding treatments. They 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 rated duty cycle of these buffer springs is in excess of 1,500,000 cycles.
Specs - Carbine & Rifle 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
Advantages:
-
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 SBR platforms.
Buffer (Action) Spring Choices and Descriptions: Choose the spring that best suits your platform
-
"WHITE Spring" STANDARD Power Buffer Spring. Equivalent spring load to a “fresh” 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. The WHITE spring is recommended for 10.0"-11.0" SBR's with H2 Buffers, 1st Gen M&P's, most RRA's under 18"+ BBL's, most Colt 6920 LE's, 5.56 & 6.8 SPC 7.5"-8.5" BBL Piston Guns with H2 Buffers, All (Known to Date) .300 BLK Platforms and when training with SRTA and other low power and light charged “budget” rounds. Color Coded WHITE.
-
“BLUE Spring” ENHANCED Power Buffer Spring, Offers improved performance with most non-suppressed 12.5"-14.5" SBR's, 16" DI Mid-Length BBLS, and all mid-length uppers with adjustable gas blocks. Best performance is usually achieved using buffers ranging from ST-2T, H2, DPMS Extra Heavy . Will run in 18"+ Length BBL RRA'S with ST-T2 Buffers, and some Colt 6920 LE's. Use of heavier buffers may not be possible with the aforementioned as well as most uppers with light weight carrier groups (VTAC, etc.) Color Coded BLUE.
-
“RED Spring” EXTRA Power Buffer Spring, Best option for 16"+ 5.56 barrels with carbine length gas system platforms with standard front sight towers and H buffers, 16" + BBL gas piston guns, *some* suppressed shorties, and 9mm, 6.8 SPC, 6.5 Grendel, .458 SOCOM, 450 Bushmaster, .500 Beowulf, and assorted "Thumpers" using standard 7" depth M4 extension tubes. AR-10 Carbines (E.G. Armalite, Noveske, LMT) using deeper extension tubes and standard length carbine buffers to accommodate the longer .308 BCG also use the "RED" Spring. Please call us to discuss successful "recipes" for implementation of the RED spring in .308, 6.8 SPC, etc. RIFLE length extension tube platforms. Color Coded RED. NOTE: NOT for use in .308 Carbines using standard 7" M4 extension tubes and short, stubby buffers. (Use the "ORANGE Spring" below for that specific 9+platform approach application.)
-
"ORANGE Spring" The ONLY specifically engineered EXTRA POWER Buffer Spring for .308 Carbine Platforms using standard 7" Depth M4 extension tubes and .308 short "stubby" buffers (Including aftermarket "heavy buffers.") You cannot clip coils from any other commercially buffer spring to yield the proper spring loads for this application, especially in heavily gassed .308 carbine platforms. We started from scratch on this design to provide Operators with a viable alternative to existing OEM and aftermarket offerings. Platforms known to exist using this approach include DPMS, Bushmaster, Remington, CMMG, Mega, SA Defense, Colt 901, and Rock River Arms. Color Coded ORANGE.
-
"GREEN Spring" In addition to use in 5.56 Fixed Stock Rifles, our “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 BBL configuration, both with or without a “can”. Color Coded GREEN.
** Please NOTE** Due to the inconsistency & minimal power factors used with low power SRTA training or SIMS Rounds, use the Standard (WHITE) Spring or designated reduced power buffer springs for these training operations.
