Modify Baton Flat Hopup Bucking Hard Type + S-Nub for Airsoft Hop-up

Worked perfectly with both of my AEGs. Using a Prometheus tbb and prowin hop up. Works perfect every time if you match up the correct Rhop patch for your barrel with the correct hop up unit (must buy both for best results). Very amazing product for such an affordable price.

Perfect fit every time I’m have several set ups and they all have elvish tac on the inside, if you’re looking for better range and accuracy buy it now

Falls in the tube, had to super glue it.

This set is on ALL of my AEG (2x Krytac, and 1x VFC Avalon) works great for something this cheap, no need to go super complicated for your upgrade.
