Vesta Defense Tachyon-S Power Barrel Extension

The Vesta Defense Tachyon-S is a power barrel extension for the Vesta Sentinel.

It adds about 4.7″ / 12 cm to the barrel.

Vesta states that the Tachyon-S can also increase the power of the Sentinel.

A standard Sentinel can produce up to 19 Joules.

With the Tachyon-S fitted, power can increase to up to 29 Joules.

This makes the Tachyon-S a useful upgrade for Sentinel owners who want more performance.

More Power for the Sentinel

The Tachyon-S is more than a barrel extension.

It is also a power upgrade.

Vesta states that the standard Sentinel can produce up to 19J.

With the Tachyon-S fitted, the launcher can reach up to 29J.

That is a possible increase of about:

+10 Joules

Actual power may vary.

CO₂ temperature, projectile weight and launcher condition can all affect the result.

For an exact reading, test the launcher with a suitable chronograph.

4.7″ Barrel Extension

The Tachyon-S adds about:

4.7 Inches / 12 cm

to the Sentinel barrel.

The longer barrel gives the expanding CO₂ more time to push the projectile.

This can help increase projectile speed and power.

Made for the Vesta Sentinel

The Tachyon-S is designed for the:

Vesta Defense Sentinel 0.50 Calibre

It should not be assumed to fit other Vesta models.

This includes:

• Vesta PDW50
• Vesta P68 Guardian

It should also not be assumed to fit Umarex or other 0.50 calibre launchers.

Easy Installation

The Tachyon-S screws directly onto the compatible Sentinel barrel.

No permanent changes are required.

Before fitting it:

• Unload the launcher
• Remove the CO₂ source
• Check the threads
• Clean away dirt
• Screw the extension on carefully

Do not force the extension onto damaged threads.

Muzzle Thread Position

The Tachyon-S moves the muzzle thread forward.

This allows compatible muzzle accessories to be fitted at the end of the longer barrel.

Always check the correct thread before adding another accessory.

Strong Metal Construction

The Tachyon-S uses CNC-machined metal.

It has a black coated finish.

The current product specification lists the weight at about 200g.

This gives the extension a solid and secure feel.
