It’s a common myth in paintball that there are more or less accurate guns. To my point of view there’s no such thing as an accurate gun – it all depends on many factors and one of them is the player himself – with the ability to shoot right and tune the marker to perfection.
But of course there are things that depend on the marker functionality. Marker’s consistency has a great impact on accuracy and it’s up to the player to fine-tune the marker so it will be able to shoot with almost the same speed for the very shot he makes. If the marker is working properly than there’s no reason for it to have a bad impact on accuracy.
The most important things are the barrel and the paintballs. The quality of the barrel (it’s length, porting and so on), the quality of the balls (their shape) and the ball-to-barrel match make the shots more accurate than ever. If you’re shooting bad quality paint than there’s no reason to complaint that your marker is not doing it’s job. It’s the paint that in most cases spoils the gameplay.
And of course one of the most important things is your shooting skills. If you’re used to shooting with markers and you’re comfortable with your gun you will definitely have better shooting results than any newbie player. So as you see it’s only up to you to improve your accuracy and it’s your responsibility to maintain your gun, buy and use good quality paint and match it with your barrel.
