Nine Ball Outer Barrel Adjustment Shim Ring Set for V2 M4 AEG (GG06-15)

The Nine Ball Outer Barrel Adjustment Shim Ring Set for V2 M4 AEG is designed to eliminate wobble and rattling in the external barrel assembly, ensuring a secure and stable fit between the outer barrel, barrel nut, and receiver. 

Purpose

The primary purpose of the shim set is to fill minor dimensional discrepancies (gaps) that are common when mixing different brands of airsoft parts, or simply due to manufacturing tolerances. By using different thicknesses of shims (commonly 0.1mm, 0.3mm, and 0.5mm are included), a user can achieve a precise, tight fit. 

• Removing Gaps: Fills the space between the barrel and the barrel nut, the barrel nut and the receiver, or the handguard and the receiver.

• Resolving Alignment Issues: Ensures the outer barrel is properly centered and aligned with the receiver and hop-up unit.

• Enabling Proper Torquing: Allows the barrel nut to be torqued down to the correct specifications while still achieving proper alignment for components like the gas tube, which might not align correctly otherwise. 

Benefits

The benefits of using the Nine Ball outer barrel shim set translate to improved overall rifle performance and durability:

• Increased Stability: A tight and stable outer barrel directly leads to a more stable inner barrel, which in turn can improve shooting consistency and accuracy.

•  Eliminates Rattling: Removes annoying "play" or rattling sounds, making the airsoft gun feel more solid and realistic.

• Prevents Premature Wear: A wobbly outer barrel can put stress on other components like the hop-up unit and inner barrel, potentially causing premature wear or damage. Shimming prevents this movement.

• Enhanced Durability: A more secure assembly is less prone to damage from impacts or strenuous use.

• Customization: The various shim thicknesses provide flexibility in custom builds, allowing users to mix and match different handguards and barrels while still achieving optimal fit.
