Question: How do you refill the air tank? Is it just compressed air from and air compressor?
Document: This gun is great!! As long as you have a electric hopper your good! This gun can shoot around 8 bps!! It is good for beginner - intermediate players (1 year of playing) it has a nice mechanical easy to push trigger! make sure you have an electric  hopper I have a halo and make sure you have a compressed air tank. If you have a gravity hopper it will be hard for the hopper to catch up to the speed of the gun (8 bps).
this marker is the best i love it my dad loves thing it the best worked great for meat first i couldn't figure it out then i got the hang of it i use it every day
this is a good gun for the price butt i have one problem about every 12 cases i cope a ball and the bolt is very hard to get out this could be fixed with a different hopper
all i have to say fast shipping and a great beginner gun.. bought this as my first gun... so yeah im a beginner ... the  package is awesome and the package came with everthing it said  readly recommend it :)
Worked great first time out; its a lot of paintball gun for the money. every time since the first outing it always chops balls and then contaminates everything with paint which causes more problems. I understand that Adzone has great tech support and maybe they can help me quickly solve the problems.
This product broke the first in the first 5 minutes of usage. If you are reading this review I urge you not TO BUY THIS PIECE OF JUNK!! !
This is probably the best deal you are going t get for a package.The Package is $127 but is worth sold for about $180.The Marker is Fantastic.
This gun is alright but chops brittle paint like crazy and to stop that paint chopping you need a tech t hush bolt wich is another $45 and even then the bolt slips out when your shooting it. Over all I wish I had gotten a tippmann gryphon instead of this gun would have saved me a lot of money.
The package came as expected and performed well. It is definitely the best marker under a 100 dollars you can buy. I advise getting a better hopper though.
Perfect starter gun with everything the recreational player needs to start playing. I bought 3 sets for my 3 grandsons. This was only their 2nd time competing, and they felt like they were pro's and had a ball. Best Xmas gift ever according to all 3 of them.
