Guarder Oil Temper Wire Tune-Up Spring (SP-140) for TM Spec AEG (GG08-09)

The Guarder SP-140 oil temper wire spring offers improved durability and consistent performance for Tokyo Marui (TM) airsoft replicas, leading to a predictable increase in muzzle velocity (FPS). Its oil-tempered Si-Cr alloy steel construction makes it highly resistant to fatigue and wear, while its progressive winding design ensures smooth compression and operation. Compatibility with TM-spec gearboxes and easy installation are also key benefits. 

Benefits of the Guarder SP-140

• Increased durability: The oil temper process makes the spring more resistant to fatigue and wear, extending its lifespan under repeated use.

• Consistent performance: Guarder springs are known for their accurate SP ratings, providing a reliable and predictable increase in muzzle velocity that is less prone to inconsistency than lower-quality springs.

• High-quality materials: It is made from oil-quenched and tempered Si-Cr alloy steel wire, a strong and durable material that can withstand heavy loads and stress.

• Smooth operation: The spring features progressive winding, which eases compression in the initial phase of the piston stroke, resulting in a smoother and more efficient operation.

• Easy installation: The spring is designed for straightforward installation, making it an easy upgrade for users looking to increase their airsoft gun's FPS.

• Broad compatibility: It is compatible with most Tokyo Marui-spec gearboxes, which are common in many airsoft AEGs.
