Tippmann M4 V1 Hop Up Nub - Enhanced flat

This nub is designed to apply even pressure on the hop up bucking and therefore is suitable for flat hop mods or the stock bucking/regular bucking. This nub is also larger in diameter than the stock one so that the play between the nub and the hole where it sits gets reduced. This gives you better grouping when shooting. This nub was designed upon request so feel free to try it out and share your thoughts with the rest of the community.

Worth mentioning: The print quality/finish on these nubs are better than the standard quality from Sculpteo, since they're printed in a higher end printer.

Installation description:

Make sure that the top arrow is pointing towards the hole where the adjustment screw sits. Double check the orientation. While pressing down the nub, assemble the adjustment screw and give it a couple of turns. This step is important, as you could damage the nub if the screw doesn't orient inside the key shaped hole! If you're not experiencing any hop up and you're sure that the bucking is correctly installed, then you may have installed the nub incorrectly. Please not that if you're planning to R-hop/flat-hop your inner barrel then you need to use item named  "Long flat -short tip" along with "DE Compression nub" . This functions as a "shock absorber" each time a BB passes but also compensates for the depth of the barrel window.
