The Gen 2 Silent Captured Spring system provides a smoother, quieter operation for AR-15 rifles without permanent modifications.
Includes an adjustable spring rate for optimization and an aluminum guide rod to reduce weight, with three stainless steel weights for buffer mass customization.
Compatible with both M4-style collapsible stocks and fixed rifle stocks, and interchangeable buffers allow for use in both AR-15 and AR-10 models.
These high-quality replacement buffer springs help maintain the proper function of your AR-15.
They are ideal for emergency spares or when assembling a parts rifle.
The springs are made to precise tolerances, with materials and finish at least equal to OEM parts.
Mil-Spec carbine buffer spring designed for AR15 carbines with a collapsible buttstock.
Not suitable for carbine models with collapsible stock when using the rifle buffer spring intended for A2 and A4 AR15 rifles with fixed buttstock.
Manufactured in the USA by Aero Precision, suitable for new builds or as replacements for worn parts.
Precision ground and polished springs for smoother, quieter operation in AR buffer tubes.
Compatible with various AR platforms, including fixed stock rifles and collapsible M4-type carbines.
Recommended for use with JP 308 Low Mass Bolt Carrier Group for enhanced performance.
The M5 .308 carbine buffer spring is designed for .308 AR's with a collapsible buttstock.
The M5 .308 rifle buffer spring is suitable for .308 AR's with a fixed buttstock.
These buffer springs are made in the USA and are not interchangeable between rifle and carbine .308 AR configurations.
The Green spring is suitable for A1/A2 fixed stock rifles with rifle length buffers and is optimized for lesser calibers like .223, 5.56, and others.
It can also be used in VLTOR A5 buffer tubes and may be appropriate for heavier calibers with long barrels when combined with H2 or H3 carbine buffers.
For over gassed heavier caliber guns with rifle length tubes, SPRINCO USA recommends their Red or Orange carbine springs with a standard carbine buffer and spacer.
The Blue spring has approximately 15% greater load than the White spring, tailored for high-performance demands.
Mike Pannone of CTT Solutions influenced the production of the Blue spring, which is suitable for a range of specimen platforms.
While often paired with an H2 or ST-T2 buffer for 14.5 - 16” ML carbines, the optimal setup can vary due to diverse gas port values.
The Hot White spring was an accidental production between White and Blue spring loads but became a valuable tuning solution.
Customers seeking an intermediate spring performance found the Hot White spring to perfectly meet their needs.
It's a good choice for those preferring Mil-Spec carbine springs, enhancing performance in most situations.
The ALG AK recoil spring is uniquely designed from chrome silicon steel for resistance to impact shock and material relaxation.
It features 2 to 3 dead coils in the center to alter the natural frequency, which helps in preventing harmonic damage and maintaining its free length.
It is compatible with AK-47 and AK-74 rifles and is manufactured by ALG Defense.
The Yellow spring is about 20% lighter than the White spring, designed in collaboration with ammunition manufacturers and gunsmiths.
It is the preferred choice from four samples tested for certain guns, with recommendations to enlarge the gas port for better reliability.
Suitable for use with low power SRTA and SIMS Rounds during training operations.
The SI Carbine Flatwire Spring enhances the service life and smooths the shooting cycle of AR systems with carbine buffer systems.
Cryo-cycled 17-7 ph steel construction ensures strength, reliability, and longevity, with added resilience to high cyclic rates.
It reduces system vibration for quicker follow-up shots and increases bolt load for more reliable feeding, while mitigating AR "twang".
The Orange buffer spring is designed for heavy caliber applications such as .308, 6.5 CM, and .260 Rem in AR-10 pattern rifles with standard 7" M4 extension tubes.
It is suitable for carbine platforms with a robust gas system, particularly in 16” - 18” ML gas carbine platforms with heavy BCGs.
This spring is also effective for tuning over-gassed carbines and can be used in AR-10 tubes with 3.25" buffers or with lesser calibers like 5.56.
