Tippmann M4 V1 Hop Up Nub - Long flat, short tip

This item is basically the same as Long flat nub but with a shortened tip to allow soft attachments on the tip (recommended attachment: DE Compression nub found here).
The DE Compression nub provides soft adjustment and optimized grouping when used with R-hop/Flat-hop patches found here.

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 may need to use item named "DE Compression nub" . This functions as a "shock absorber" each time a BB passes but also compensates for the depth of the barrel window.
