Tippmann M4 V1 Hop Up Nub - Long flat (above #2500

The idea behind this nub is to provide a larger surface area which will be in contact with the hop up rubber. Along with a slightly larger diameter which reduces side-to-side play, this results in a more stable grouping when shooting. Ideal for both stock hop up rubber and flat hop modifications.

Main difference between this nub and Nub - Enhanced flat is a longer body which makes it more stable. The total length of this nub extends to the point just before the upper surface of the receiver (it's not sticking out).

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.
