M16 RIFLE CS STANDARD SPRING KIT

SPRINCO USA

In stock

£31.90 * £31.90 - £34.90*

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.

Extractor Springs

Sprinco USA's XP 5-Coil extractor spring is stronger than OEM springs, eliminating the need for additional modifications like a D-Fender™ ring or CRANE Viton O-Rings.
The enhanced 4-Coil springs are ideal for 18" or longer barrels, maintaining the load of a new Mil-Spec spring, while the 5-Coil version is suitable for all 5.56 barrel lengths but may be too strong for some bolts.
These extractor springs can withstand temperatures up to 750°F, are designed for extreme duty cycles, and may be the only extractor springs needed for the lifetime of a bolt.

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.

Extractor Springs

Sprinco's Extractor Springs are heat treated and cryogenically processed for durability, and can handle heat up to 750°F without performance degradation.
The XP 5-Coil spring offers a heavier load than standard OEM springs, making additional D-Fender™ rings or CRANE Viton O-Rings unnecessary.

It is suitable for a variety of calibers including 9mm, 6.8 SPC, 6.5 Grendel, and others, but compatibility may vary based on individual firearm specifications and ammunition loads.
