I have designed the Master Class Kit to include the most sought after upgrades
on both the CO2 guns and the Pumper guns. This is the kit to buy if you want
to quickly and easily upgrade a bone-stock Crosman to an accurate, powerful
pellet gun. The kit includes:
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.

Two Stage Trigger and Power Pack Plus

Flat Man's Pack and Steel Breech (both calibers available)

24" barrel for reference and fiber optic sight |
