The set includes:

1/ Beoranged Howitzer Front Bolt /A5, X7/
    Product description:
The Howitzer is made of Polyoxymethyl which is an easy sliding and self lubricant plastic that makes any internal scratching of the marker impossible.
The tip of the bolt is fade colored in orange. A second internal O-ring seals the air between the power tube and the bolt. The result is a higher (gas) efficiency and better performance of the complete system.

2/  JCS A5/X7 RED HOT POWER TUBE
    
Product description:
Constructed of lightweight, strong aircraft aluminum, the red anodized JCS power tube eliminates the possibility of cracking and breaking, associated with the stock A-5 plastic power tubes that occasionally crack and break - due to freezing associated with C02.

For Tippmann A-5 owners running C02, the JCS Red Hot power tube may prove to be one of the most significant add-ons you purchase – giving you the biggest bang for the buck, literally and figuratively.
Many users of the Red Hot power tube have also reported enhanced marker accuracy, more efficient use of air, and improved response over the stock tube.
It can be installed quickly and easily, and the upgraded front velocity adjuster results in a near-perfect tight-fitting, secure front velocity screw.

The JCS power tube produces a significantly louder pop, especially with short barrels. Whether the added noise is a positive or a negative attribute depends on your particular style of play.
When laying heavy suppression fire on opponents, some players prefer the "intimidation factor" of the louder noise; however, if stealth is a big part of your game, make sure your first shot is on target, because your location won't be a secret for long.

3/ New Designz V2 Turbo Valve Housing for Tippmann A5/X7
     Product description:
Will all the powertubes on the market, many players wonder why no one ever focused on the heart of the air system: the valve assembly.
New Designz has done just that with the release of the
New Designz V2 Turbo Valve Housing for the A5, X7 and BT4 paintball guns (basically markers that use the Tippmann valve design).

New and improved 3 port design. It was challenging to exceed the X7 valve, but with numerous prototypes this valve has surpassed the performance of the X7 4 port valve.
This will fit all makers that currently have the tombstone as the air inlet supply.
The valve body features ramped inlet and exhaust ports for improved flow, smaller front direct porting, 3rd top port and all of these combined will help increase velocity and efficiency of these markers.
This will allow for reduced input pressures and reduced spring rates.

Features: Ramped inlet & exhaust ports for improved air flow Smaller front port for direct flow 3rd top port for improved flow Adds 10-20+fps over high flow X7 valve using CO2 or air Add our optional weight kit for 14 different weight combination's reducing kick Made in the USA
