Product Description
ALG Defense AK High-Energy Main Spring — Heavy-Duty Recoil Spring for AK Platforms
Give your AK build hardened, reliable cycling with the ALG Defense AK High-Energy Main Spring. Engineered for shooters who demand extra spring force—whether you run suppressed setups, short barrels, high-round training, or heavy buffers—this high-energy main spring delivers stronger return force, reduced spring-set, and consistent bolt carrier timing for dependable function under stress.
Why it matters
Standard factory springs can lose tension after heavy use or struggle with altered gas dynamics from suppressors and SBR builds. The ALG High-Energy spring provides the extra push your bolt carrier needs to ensure reliable extraction, feeding, and ignition across a wider range of ammo and operating conditions.
Key Features
-
High-energy design — increased spring rate for stronger bolt carrier return and improved timing.
-
Premium spring steel — heat treated for durability and long service life.
-
Corrosion-resistant finish — protects against rust and wear in field conditions.
-
Factory-pattern dimensions — direct, drop-in replacement for standard AK main springs.
-
Low spring-set — engineered to resist permanent deformation over high round counts.
Benefits
-
Improved reliability with suppressed, short-barrel, and high-pressure rounds.
-
More consistent extraction and feeding, reducing malfunctions in adverse conditions.
-
Longer service life versus worn or economy springs—less frequent replacement.
-
Simple swap — no gunsmithing required; installs like the OEM spring.
Compatibility
-
Platforms: AK-47, AKM, AK-74 and most AK-pattern rifles using the standard factory main/recoil spring.

Remove the receiver cover and existing recoil assembly per your manual.
