I agree . Same thing with auto magazine loader. Most of their other prices are reasonable. But I can do without . 
Go ahead and get a Tippmann, you will like it. I have no problem with the factory one.Would a standard AR15 charging handle work or is the Tippmann a special design ,I’ve been thinking of getting a Tippmann.
I look on the: M4-22 Aluminum Ambidextrous Charging Handle
It look very cool, but it prise is high... (price + delivery cost).
If rifle cost 600$, price Charging Handle 100$ is 15% cost all rifle.
I think is value Aluminum Ambidextrous Charging Handle is "overpriced".
When Tippmann has sale? I ask becouse I don't know US market.
