Strike Industries Flat Wire Spring – AR Carbine Key Features
Model: AR Carbine Flat Wire Spring
Part Number: ARFWSC
Material: Silver stainless steel flat wire
Finish: Natural silver stainless
Compatibility: AR-pattern rifles with carbine-length buffer tubes
Function: Replacement / upgrade recoil spring for AR carbine buffer systems
Designed Specifically for AR Carbine Buffer Systems
The Strike Industries Flat Wire Spring is purpose-built for carbine-length AR buffer assemblies, making it ideal for:
Standard AR-15 carbines with collapsible stocks
AR pistols and SBRs using carbine-length receiver extensions
Builds chambered in 5.56/.223, .300 BLK, 7.62x39, 6.5 Grendel, and other AR calibers using carbine buffer systems
It drops in as a direct replacement for your existing carbine recoil spring, requiring no special tools or gunsmithing. Just swap it in when you’re already in the buffer tube for cleaning or upgrades.
Stainless Steel Flat Wire – Built for Longevity & Consistency
Unlike traditional round-wire music steel springs, the Strike Flat Wire Spring is made from premium stainless steel flat wire, which offers several advantages:
Extended service life compared to standard springs
Better resistance to set and fatigue over high round counts
Increased corrosion resistance for rifles exposed to sweat, humidity, rain, and harsh cleaning environments
More consistent compression characteristics, helping maintain reliable cycling over time
If you shoot a lot, run classes, or keep a rifle as a dedicated defensive or duty gun, this is exactly the kind of long-life spring you want at the heart of your recoil system.
Smoother Recoil Impulse & Reduced “Twang”
One of the most noticeable benefits of a quality flat wire spring is the improvement in feel. The Strike ARFWSC helps provide:
A smoother recoil impulse, reducing that choppy or “bouncy” feel of some stock setups
Reduced “sprong/twang” sound in the buffer tube when firing
A more controlled return to battery, aiding in faster follow-up shots and better sight recovery
While it doesn’t change physics, a well-tuned flat wire spring can make your AR feel much more refined, especially during rapid strings of fire.
Optimized Coil Geometry – More Spring in the Same Space
Flat wire construction allows more effective spring material to fit within the same overall length, which can:
Increase effective energy storage without excessive preload
Help maintain consistent tension across the stroke of the buffer
Provide a more linear compression feel through the entire cycle
All of this contributes to reliable feeding, consistent ejection, and softer perception of recoil, particularly in carbines that see mixed ammo types or suppressed use.
Corrosion-Resistant Silver Stainless Finish
The ARFWSC features a clean silver stainless finish that’s not just about looks—it’s about protection:
Stands up to moisture and carbon better than untreated music wire
Ideal for rifles stored in vehicles, humid climates, or less-than-ideal conditions
Easier to inspect visually for wear, damage, or fouling
Pair it with a quality buffer and proper lubrication, and you’ll have a recoil system that shrugs off hard use and rough environments.
Drop-In Installation – Easy Upgrade for Any Builder
Installing the Strike Industries Flat Wire Spring is straightforward:
Ensure your rifle is unloaded and safe.
Remove the stock and buffer retaining pin to take out your buffer and old recoil spring.
Slide the old spring off the buffer and replace it with the Strike Industries flat wire spring.
Reinsert the buffer and spring into the carbine buffer tube and reassemble.
In just a few minutes, you’ve completed a high-impact upgrade that improves feel, reliability, and longevity.
Perfect for Duty, Defense, Competition & Training
This spring is an excellent choice for:
Defensive / home-defense AR builds where reliability is non-negotiable
Duty and patrol rifles that must run in all conditions
Competition carbines where smoother recoil helps with speed and control
Training and high-round-count rifles that put serious mileage on internal parts
If you want a recoil system that stays consistent from round 1 to round 10,000+, a stainless flat wire spring is a smart foundation.
