Lower your MOA with a hit-area smaller than head size. Paired with the right ammunition, tighter groupings at range will enable you to acquire targets swiftly and confidently, knowing that your shots will land where you intended.

Feed only the best. The right weight and quality BB is crucial in getting the most performance. Your R-Hop is taking on the shape of your BBs, creating a perfect fit over time.

Equipped with the Prowin Hop Up Unit designed for our Flat Nub and R-Hop Modification. We are installing a high density rubber patch in the hop up window and then polish it perfectly flush and flat to the inside of the barrel to ensure perfect fitment.

Heading

Newton's third Law

The backspin provided by Hop Up magnifies the effect of drag between the BBs surface and the air. Air is accelerated on the top edge, in the direction of the spin, and slowed down on the bottom edge, due to increased drag. The resulting net downward force creates an equal upward deflective force.

Magnus Force
The angular deflection in the fluid flow, after the BB, imposes a deflective force on the body in the direction of the spin.

Featuring

All of these features combine to offer the user a higher performing Airsoft weapon, making the rifle more versatile between different scenarios. Due to the stronger and more consistent pressure we are putting on the BB we are now able to use heavier BBs. Those heavy BBs which will ensure less drift in windy situations and enable you to reach out even further than with light weight BBs.

Using recommended BBs

Rigorous testing of ever barrel we hand make is our key to ensure absolute perfection. The modification is designed to ensure that a BB is able to pass through the barrel smoothly, while minimizing the space between the BB and the R-Hop when no Hop is applied. This ensure that you can tune your Hop Up to perfection by making very subtle changes to your hop.

Our warranty covers manufacturing defects only. Professional installation is recommended. Make sure to use a proper flat-hop bucking or properly modified bucking with this barrel, in case you do not use the full-unit. Professional and accurate installation of the M-Nub into the Hop Up Chamber required. Take good care of the R-hop patch and clean it regularly. Swelling due to oils, scratches, etc not covered; Must include proof of purchase, barrel, and original patch.

Issues In case you experience excessive over hop it can be avoided by using heavier BBs and ensuring that your M-Nub is not applying any hop when set to its neutral position. Should you still experience over hop shave down your M-Nub to shorten and thereby optimize the distance it protrudes into the chamber. This is especially crucial in case you are not ordering our complete Hop Up set up where this tuning has already been done by our technicians.
