I've only shot about a case of paint through it, but found that the GT Commando 2 is a surprisingly accurate gun. The stock barrel in Micro-honed and seemed to give the paintballs stability. The gun come standard with a fitted carrying case, shoulder stock and double trigger. All O-rings are the same size as your CO2 tanks. Cleaning is a breeze. It's comfortable to use and looks great!!! You'll get many "OOOOs" and "AHHHs" from people who first see it.
As I said before, I only shot about a case of paint though it. I used it in one "pick-up" game so far. The gun seems to have bee shipped from the factory with a internal leak in it, the connection to the CO2 tank seems to be threaded slightly off, and the trigger snapped in half!!! Needless to say I contacted the company immediately because the gun is under warranty. They would not guarantee the cost of shipment for me on a gun one week old. This is still going on so I can't let you know how it's all going to end.
Overall, I rate the gun itself very highly, I like the look and feel of it. It shoots like a dream and is VERY comfortable to shoulder & carry. I can't quite condemn the entire gun for short-comings that might be due to one time manufacturing errors. If that was the general contentious; GM, Ford, Microsoft, etc.. would be in real trouble. I'd give this product a 10 if it weren't for these issues. But seeing these issue exit currently, I'll give it a 8.
