Only for Cyclone Feed Tippmans, I would not consider it a weakness though
Review:
This is one wopper of a hopper!
450 rounds on top of your gun.
My field doesn't count gun hits so the size isn't an issue.
This is a heavy gunners wet dream.
The extra paint does add some weight but if you are looking at this you know that already and should be able to handle it..
Construction is solid, hopper fits tight, lid snaps shut tight.
I tried in my A-5 which is 1.5 years old and also my 98 w/Cyclone which is brand new and they both fit tight.
I had the 350 hopper from APP before and it is wider than the 450.
The 450 is longer with a similar shape like a ricochet hopper.
I have not tried the offset mount because I don't use a scope, I usually walk in my shots in.
If size does matter to you, then this is the hopper for you.
Conclusion:
If you are a heavy gunner this is the hopper for you.
If you have a Double Trouble or Hammer buy 2.
The size, the quality of the workmanship, and the company stands behind their product. Anybody who is complaining about an APP product didn't call the company.
