The second factor is exactly how an R-Hop applies the pressure. In a traditional system, you have a curved nub protruding into the barrel and when the BB passes underneath, it deforms and flattens out slightly. An R-Hop applies the pressure gradually and evenly, meaning there are fewer variables and inconsistencies through excessive movement. Another theoretical but anecdotally proven beneficial effect of applying the pressure like this, is that the BB leaves the patch much more smoothly, resulting in fewer bounces along the inside of the barrel.
When an R-Hop is correctly installed, there is a very slight protrusion along the whole length and breadth of the hop window, on the inside. This allows the BB to touch not just a single point but a whole curve. If your R-Hop patch is centered, then your BB is centered and when it leaves the patch along the barrel, it is much less likely to come into contact with the sides of the barrel.
The ideal scenario is that the BB travels straight down the centre of the barrel, without touching the sides at all. Any touch from the barrel will impart friction and therefore adjust the direction of spin from being exactly backwards to slightly to one side.
Traditional hop rubbers protrude into the barrel more in the middle and less to the edges. This necessarily holds the BB very slightly to one side, greatly increasing the chances of off-axis friction and is what gives you those annoying fly-aways at extreme range or less depending on the quality of the setup.
The fourth main factor involved in the effectiveness of R-Hops, is that they do not need to protrude into the barrel as much. I touched on this earlier: because the R-Hop patch is longer, it needs to protrude less into the barrel in order to apply the same or greater amounts of friction. This allows the air pressure to transfer the energy more efficiently to the BB, resulting in less of an fps drop per amount of backspin. Of course, this effect must be taken into account when designing the build so it does not fall foul of any power limits.
The last main factor is the separation of the method of backspin from the air seal. Tradition hop rubbers are single units which must apply backspin and seal against the barrel and nozzle. This means a compromise must be made between the aforementioned levels of hardness. The method of backspin has been separated from the method of air seal so the tech is free to choose the most suitable rubber for the given setup. As you can see, there are a number of advantages to a properly tuned R-Hop.
Greater consistency, more backspin allowing heavier ammo; and better efficiency. All of these advantages are evident when using common weights of ammo but they are further enhanced by using even heavier ammo still. Wind and other variables will have a lesser effect. We all know that heavier ammo will have a lower fps in the same gun as lighter ammo but what is often not realised, is that the energy level at the muzzle is the same.
So the heavier BB might be going slightly slower but it has just as much energy and because it bleeds off this energy slower conservation of momentum , it will have more energy left at any given distance than lighter ammo. Heavier ammo is more affected by Gravity which is why more backspin is required. It also takes longer to apply the backspin due to the weight and this is where an elongated patch really shines. Not only does a heavier BB have greater forward momentum, it has greater angular momentum.
For example. I understand that might have been a little more jargon than is useful so basically, what that means is that heavier ammo can fly further due to the speed bleeding off slower and fly further due to the backspin bleeding off slower. Traditional systems cannot apply enough backspin for the really heavy ammo 0. The speed bump is an aggressive way of applying the backspin and because of this the BB vibrates and bounces down the barrel as it exits; this impacts on effective range and accuracy of your Airsoft Gun.
R-hop is less like a speed bump and more like a gentle hill, both impart the same amount of backspin but an R-hop does it in a much gentler fashion. Imagine hitting a speed bump at 60mph compared to a small hill. The added benefit here, is that you can apply more backspin to heavier BBs. In addition to this, the 'speed bump' is now the same curvature as the BB see diagram below , allowing the BB to be centralised in the barrel during firing.
