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

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 AR platforms.

Includes:

  • H1 Carbine buffer W/ Tungsten Weight (1) and Steel Weights (2). (3.8oz)
  • Sprinco Enhanced Power Buffer spring (Blue)
  • Made in the USA

Sprinco Spring:

  • 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 mid-length gas systems, short barreled rifles with carbine length gas systems, etc.

H1 Buffer:

H1 (Heavy) Buffer for your carbine, AR15, M4 Standard USGI part for the M4 Carbine. The heavier weight buffer is used to slow down the cycle rate on carbine style AR rifles which helps lengthen receiver life. A heavyweight buffer could potentially increase performance on hotter loads by slowing the cycle rate enough to allow the magazine to ready a new round for the chamber. Weight: 3.8oz

  3. Duane I. (verified owner) –

    Great advise on great product

  4. Anonymous (verified owner) –

    I’ve previously paid close to this price for JUST Sprinco Blue carbine springs alone. While the buffer has an anodized housing, it functions flawlessly and makes the combo pricing a super deal.

  5. Robert K. (verified owner) –

    Great to deal with

  6. Anonymous (verified owner) –

    All good.

  7. Duane (verified owner) –

    repeat purchase, would buy again

  8. Andre (verified owner) –

    This combo made my 10.5” barrel build cycle great and lock open on the last round, loving it.
