Maby some extra tubes if it's a primairy
Replacement Bolt... do they even make them?
Sealed C02 Chamber
Over all and excelent and phenominally reliable gun. It has a closed co2 chamber which means that even if the co2 doesn't puncture and set appropriately there wont be any leaks. It's like putting your tank inside a little tank.
It's easy to add a bottom line if you wanted it and it's very easy to load. If you reload the 10 rd clip while it's still on the marker you can actually get 12 balls into it.
The gun is very compact which is really the only reason for its minimal weaknesses. The barrell could be longer or have some porting but since it's a pistol that would defeat the purpose. However it would be nice if they'd added some threads so a barrell could be added if you wanted it. As is your stuck with stock. Because the barrell is so short (It's a pistol) the accuracy is somewhat lacking but it's reliable enough to shoot. The spread is about a foot at 50 feet and a little more at 100.
The bolt is actually preety cleverly designed given the stringent requirements but I think they could have done a better job. When the bolt is cocked it doesn't sit quite right in the barrell and you can wiggle it around with you fingers about 1/4 a mm. It doesn't affect anything it's just a little obnixous and is probably caused by the bolt's length, just over an inch. My bolt however still had some of the metal shavings on it. I just took them off with a modeling knife.
The gun gets excelent co2 mileage. It shoots over 30 shots on one 12 gram when firing less than about 4 bps even at max velocity.
If for some reason your upside down when your shooting make sure you dont shoot the last ball because it will cop guaranteed. The spring loaded feader will only push the last ball into the chamber 1/2 way and then it runs out of spring power and since gravity is working against you on that ball it's 1/2 in 1/2 out.
Definately an excelent pistol. In this price range I think you'd be hard pressed to find a better performance. I'm sure the $500 pistols are better but honestly, whats the point? If your looking for a cheep pistol for playing around with this is the one to get. If you want a primairy weapon, this is still good but you'll be out classed by some people.
