Sprinco Buffer (Action) Springs

Details

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.

First clued in to these springs by former US Marine and US Army Special Forces solider and trainer Mike Pannone, the staff at Weapon Outfitters have run a SprinCo springs in our rifles since 2008. We at Weapon Outfitters fully endorse the Sprinco spring's performance and longevity.

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: 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

  • BLUEMedium "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 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

  • YELLOW 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 Rifle Length Spring

In addition to use in 5.56 Fixed Stock Rifles, 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 specifcally engineered for .308 Carbine Platforms that use 7" Depth M4 extension tubes and short 2.5" Buffers (including aftermarket "heavy buffers"), this list includes: DPMS, Bushmaster (Post 2010), Remington, CMMG, Mega, SA Defense, Colt 901, Rock River Arms, and more

SBR build

Posted by Evan | (Posted on 12/15/2018)

I recently built an 11.5 in. SBR. As I kind of anticipated, I was over gassed and having frequent malfunctions. I bought the blue spring and paired it with an H2 buffer. Zero issues since. Great product, couldn’t be happier with the results.

Important upgrade

Posted by Justin | (Posted on 8/17/2014)

One of the best upgrades to your rifle without dumping hundreds of dollars, the Sprinco spring helps to improve performance by slowing down the action on most over-gassed carbines, reducing felt recoil, and lasts longer than your conventional springs.
