Description

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:

  • Lightweight Carbine buffer W/ 2 Steel Weights and 1 Aluminum weight (2.7oz)
  • Sprinco Reduced Power Buffer spring (Yellow)
  • Made in the USA

Sprinco Spring:

  • YELLOW:  Reduced Power Spring

Useful for under gassed rifles, such as some mid-length gas rifles, “Dissipator” builds or 300 blackouts that short stroke or have weak ejection patterns trying to shoot subsonic’s without a suppressor. 

Lightweight Buffer:

BKF Industries AR15 Lightweight carbine buffer for use in AR15 carbines with a collapsible Carbine buttstock. These are made for tuning specialty subsonic loads in platforms like 300 BLK. It is not recommended to use with full power loads.

  5. Jacob A. (verified owner) –

    Only had time for one outing so far. Required an adjustment to my gas block but that was kinda the point. Small but noticable difference in weight.

  6. Pete (verified owner) –

    Lightning fast shipping. Good price.

  7. Greg (verified owner) –

    Perfect addition to a mid-length build with a 12.5″ barrel, needing a a lighter recoil system.

  8. Eric (verified owner) –

    Shipped fast and totally fixed my short cycle issues.

  9. Ryan P. (verified owner) –

    Absolutely fantastic! Fixed my feeding issue in my 7.5” .300 blackout! 220 grain wasn’t working right even after I put the suppressor on and this lighter spring and buffer corrected my issue immediately!

  10. Wesley (verified owner) –

    Couldn’t be happier! This setup allowed me to reliably run subsonic 300blk ammo in one of my at platforms. Because why not! BKing’s Firearms was awesome to deal with, ideas shipped fast and with no hiccups. I will be ordering again soon!

  17. G W. (verified owner) –

    This buffer and spring combo worked great in my 300 blackout pistol build. It fixed all the cycling issues I was having. Now I can run 150gr down to 120gr without any issues.

  18. Hector Midence (verified owner) –

    It did not solve my problem with the short stroke and the BCG not coming back into battery. I’m back to zero in figuring out why it did not work.

    Works great no problems!!

  38. MARK R. (verified owner) –

    Just what i was looking for my short barreled suppressed 300 AAC

  39. Geoffrey (verified owner) –

    Spring works as intended, allows my rifle to shoot lower powered .223 steel case as opposed to my normal spring that only allows for function with .223 or 5.56 brass case.

    Fixed the error of ejecting a spent case but not chambering a new round due to the bolt not traveling the entire length of pull.

    I reccoment this product for this error only in borderline cases where the bolt is almost fully functional, but barely not. If you have more severe cycling issues, I reccomend you make adjustments to your gas system instead as lowering the spring force will not drastically change your rifles performance.

    Fast shipping and product is good.

  42. Christopher (verified owner) –

    My 7.62×39 10.5″ pistol upper, with carbine length gas system (very short dwell time) would occasionally short cycle when using American made ammo. It must be loaded slightly under powered. This took care of that, runs like a champ now. No issues! Great value!
