The Worker MOD Alloy Scar barrel tube is specially design for Prophecy-R blaster, of course many nerf could make use of this barrel tube onto the stefan ready LongShot and Retaliator. This integrated design with the alloy barrel tube and scar rifling muzzle together to induce a 0.5 rotation spin (which means the dart will spin half a turn or 180 degree) from enter till it exit the muzzle. The friction within the muzzle will cause a drop of fps and also adding spin to a dart will result a reduction of blaster range, but in exchange of accuracy.

This allows you to hip fire more accurately or even fit on a proper scope/sights and use your blaster as a 'sniper'. You will be pleased with what this thing can do.
