I have designed the Master Class Kit to include the most sought after upgrades on both the CO

The kit includes:

• The Two Stage Trigger
• Applicable Power Mods
        Power Pack Plus for CO2
        Flat Man's Pack for Pumpers
        See details below.
• .177 or .22 Steel Breech [Shaved Steel Breech Mod info]
• Longer Barrel (.22 only, max 24 inch length)
• Fiber Optic Front Sight
• Includes Plastic 2289 Barrel Band on Longer Barrel Pumper Orders
        Upgradeable to Metal 2289 Band

On the CO₂ guns, you will receive the Power Pack Plus as the power mods. That's the power valve, power spring, bored out bushing.

On the pumper guns, you'll receive the Flat Man's Kit, which is the Flat Top Valve / Piston, power spring, bored out bushing.

And a longer barrel of your choice, up to 24".
