The widely accepted answer is that the rifling imparts spin on the dart to make it more accurate. Why SCAR barrels make a dart fly more accurately has been up to debate, and more research is needed. Due to this, these barrels are usually used on very high velocity blasters. Bearing-based rotation barrels impart less friction on the dart as the bearing rollers do not affect it as much as strings or channels. These barrels use either strings (usually fishing line), plastic channels, or bearing rollers to act as rifling on the dart, increasing accuracy while also decreasing velocity due to added friction. Some barrel extensions, like the Mega Dart Barrel Extension, double as their own blaster.Ī special barrel extension piece found on some homemade/third party blasters are known as String-based auto centering and rotating ( SCAR) barrels, Printed centering and rotating ( PCAR) barrels, and Bearing-based auto centering and rotating ( BCAR) barrels. It's important to note that these types of barrels will only increase performance on blasters that have their own compression barrels, and if there is a seal between the blaster's barrel and the barrel extension's barrel putting these barrels on any other blaster (which is usually not possible without modification anyway) will actually decrease performance as they would introduce even more friction than a conventional barrel extension.ĭue to their negative effect on performance, barrel extensions are mostly used for aesthetics on blasters or provide other features such as added tactical rail space. Their inner barrels are often made of metal. These barrel extensions prolong the amount of time the dart is in contact with compressed air. The only types of barrel extensions that increase performance are those that act as compression barrels, such as the Deuce Pro's barrel extension. Some barrel extensions may have a wider inner barrel which remedies these issues. Secondly, in the confines of a barrel, there is less room for air in front of the dart to escape to, so friction from the air increases. Firstly, the dart may bounce around and hit the walls of the barrel, losing kinetic energy. However, in most cases, the increase in accuracy from a barrel extension is negligible, if there is any.īarrel extensions almost always cause a decrease in velocity due to two primary reasons. the dart immediately swerves off course as soon as it leaves the barrel) a barrel extension may help correct its path for at least the length of the extension, although it would in turn introduce a lot of drag on the dart due to it contacting the sides of the barrel. It can be argued that if a blaster is grossly inaccurate (e.g. 1.1 Auto centering and rotating barrelsīarrel extensions are said to make blasters more accurate, however, this is widely disputed the popular Elite Dart and previously popular Streamline Dart are known to be inaccurate even with extensions equipped.
