This is the strightist shooting most accurite barrel on the market. If you want to go out and buy only 1barrel this is the one. You can shoot virtually any brand of paint through it provided it is of reasonable quality and It is not too heavy either. It is als one of the quitest barrels I have ever shot.
The G-1 dose not shoot well with broken paint at all in fact if you break a ball you need a spray bottel to clean out all the small porting. It is not the lightest barrel on the market similar to the boomstick. Also seperation of the front and back of the barrel is not as unheard of as it should be.
I have used 12 to 16 inch barrels on cockers sniper II and angels they are the most accurite thing I have ever used and it is also relitivly simple to anodize it to match your gun. The spacers give it a versility that was unheard of when it first came out and it is the standard for multi bore sized barrels. It is well worth the cost and blows all similar barrels out of the water. The small proting was even corrected on the latest generation and I would reccoment it to anyone willing to spend the money. One of the if not the best barrel out there difinatly outstanding.
