I used to have a small orion but it does not even compare with the Tippmann A-5
Tipmann marker with car stock remote line flatline and anti-chop bolt.
I would probably buy an expansion chamber
Very good aim and range with the flatline.
Cyclone feeder very effective in preventing chopping,
Little bit heavy when first start to use it
Can be hard on air.
The tippmann ha improved my game immensley since I got it. I am able to pick off guys with one shot with the flatline. If you add the stock it only increases your aim because it holds the steadier. I would recommend an expnsion chamber thogh because it caan be hard on air. I don't think you would need to buy an electronic trigger because it shoots just as fst as you can pull the trigger. Another upgrad I would recommend woul be a scope, it combined with the flatline would make a deadly combination. It is bit heavy when you first get it but you get used to it really fast.
Overall I would recommend this product for even the more serious paintballers, it is a very good gun with very little chopping. Great for begginners and vetrans.
