"LOVE this setup with 410mm 6.03 barrel, R-Hop, ProWin Hopup, solid cyinder and M130 spring on my Valken MKIII SPR build.

Cannot go wrong with this Flat-Hop bucking and nub. Thinking about trying the Omega, Panthera or other concave nub to see if it makes a big difference...
by Edward M. on 07/08/2023

Fine bucking for moderate accuracy and distance improvements. However the bucking may rip a little from the nub if you use it on an AEG over 1.2J with heavier BBs. That being said, it's a universally great upgrade to have if you had to upgrade anything.

"This is a must-have upgrade for any stock airsoft gun.

This fits any M4 within reason. I have used about 4 of these. Use the soft for indoor (.20's) and hard for anything above (.25s).

This is a super easy mod that takes less than 15 minutes and does increase your range a bit, I don't have an exact number, you won't be shooting the moon or anything but it is very noticeable. Just put one in thank me later.
