"RHOP" what do folks know about this.

[2nd Bat]

I had a local shop hyping the advantages of a new system he callec "R" hop. Apparently instead of a nub effecting the bbs spin the bucking is such that the surface is more of a flat mat with the nub on the reverse side. Supposedly the friction is more even, more consistent and reduced air pressure loss at the hop up. The tech at the shop swears by it. It is able to be installed in virtually all guns.

Anyone know anything about this?

[masterchef]

A few of the eastwind guys swear by them as well, the concept as I understood it was you exchanged the standard nub for a more flat, long piece to ensure more consistant hop is applied to each bb. I've toyed with the idea of trying it in my mg3 but haven't found the time.

As long as you already have the necessary upgrades it will be the best investment you will ever make into your gun. My primary rifle (VFC m4 with G&P v2 gearbox and Madbull 6.03 TBB) is dialed in at about 390 fps with .20's. Using .30's I am able to hit man sized targets at 250 plus feet with no problem since having a buddy install the RHop. I am planning on putting one into every AEG I own.

Im A tech At Fox airsoft and we do installs of R hops as well.

They are really great, I have R hopped all of my guns. Probably the best investment you can make in your gun.

The best part is that you can do this to a stock gun and still get fantastic range out of the gun without other upgrades.

I actually made my own hop spacer using a BB I filed down flat and in addition to removing the hoprubber nub and rotating it so it uses the smooth side of the hoprubber. Works really well in my garand.

While that gets some of the effect of an R hop, I dont think it gets the full effect. The contact patches that we use are made by a local company Milsim Labs and they work great, If the R hop is used in a Steel barrel the effects are magnified, the vibrations are reduced as a result of the heavier metal. Using a proper Mnub that is cut correctly you can reach 100 yards or more.

I know thats hard to believe but with a .28g BB in a 363mm Bravo Steel barrel thats the results we were getting.

[2nd Bat]

Not to sound like a doubter (and I absolutely mean that). but describe with some detail what your "testing" procedures are?

[elder90]

We measured the distance at 300 feet, with a refrigerator door at the end of the 300 feet

With a 363mm Bravo (Steel) Barrel in a Upgraded VFC SCAR-L shooting 405 FPS with a .2g (In the test We used a .28) hit the door every time and could keep going past the 300 feet but we cant measure past that because that's all the room we have to test.

A very good friend of mine as a ICS M16 that has been DMR'ed, In Colorado the rules for such a rifle are 450FPS w/ a .20 and semi only.

He has a 509mm Madbul Black Python (Aircraft aluminum) in it and its shooting over the limit currently (465ish FPS) and it has the most range of any airsoft gun I have ever seen in my life.

I know its really hard to believe because for the longest time a airsoft gun that can hit 100 yards was not possible, but this R hop is so great, Ive done it to all of my guns now. Its great to watch bbs fall at your feet and you just aim straight at the guy and nail him on the first few rounds.

Interesting. Thanks for sharing. Id like to hear additional experiences. Ive always used a 12 inch pie plate as a long range target as it provides a nice audible ping when hit and you can even get a pretty good sence for how hard it hits. Its always amazing to me how few airsofters really have any sort of accurate idea about their weapons range or trajectory. An interesting characteristic of airsoft bbs is that once they loose their initiative the bbs almost literally stop in mid air and drop. From the shooters perspective these bbs often appear to be going much further than they really are. The tin audible target is one way to guage whats happening although ideal is to have a spotter down range inspecting directly the flight of the round. The other key discovery from deliberate and science based testing is realizing how much quicker lighter bbs lose velocity while heavier bbs maintain their inertia so much better. Hence providing greater range. It sounds like rhop has even greater influence on heavier bbs than lighter bbs and also that setting the hop more precisely is even more critical than with traditional hop up.

I'd be interested in such a mod being shipped to me to install in my custom .30 I'm finishing put me into contact with who I need to be in contact with please.

Charley, unfortunately the Hopup has to be modified as does the barrel and the gun tested to insure it fires properly, its a very fine art installing a R hop, you may have to disassemble it multiple times to get it right (Although We pretty much have it down it took several months to have the install time to about an hour and a half depending on the gun). So unfortunately you would have to ship the gun into us and we would do it for you, make sure everything is done well, test and send it back to you.

Very true 2ndBat, With the Rhop, how it creates such great range is it smoothes out the Contact with the BB so instead of "popping" under the nub/bucking it rolls accross it. The result is the BB doesn't rotate on multiple axis and only rotates on one.

The Ballistics behind it are very interesting.

Somehow I think shipping an all steel .30 would be cost prohibitive. I'll keep looking into it to perhaps do it myself or have it done by someone local.

OH you ment M1919? Yeah, shipping that in would be a little much. Let me talk to my head tech and see if you could send in the Hopup if we could get away with that.

What Kind of hopup do you use? M14?

[CharleyNovember]

P90 currently, but experimenting for final.

[elder90]

I called the head tech and he said that you can send it in but you cant expect the greatest results because each contact patch has to be tuned to the specific gun.

Is this a service that you are offering? Im quite interested!

Yes Paladin, I am a Tech at Fox Airsoft a airsoft shop out of Colorado and I have been a member on here for a while and just stumbled on this thread and thought I could help answer some questions

This is our website, if you are interested in getting an R hop done give us a call and Ask to talk to either Kent Zimmerman (He is the head tech) or myself Tanner Caillouet. I wont be in the shop until the end of the week but Zimm will be there all day today.

The reports on rhop do seem to be consistently positive which is encouraging. Often times these things are more hype or fantasy than reality but I have heard very encouraging statements from people i trust but all indicate that proper installation is the key. I have NOT actually seen comparisons in anything close to a scientific circumstance and would love to have that opportunity. The one fellow i know who has experimented with it the most (Brad at Sirplus) has stated that based on his testing the effect on range is not as great as the hype implies but it absolutely has a pronounced impact on consistency and hence accuracy. In spite of not seeing dramatic improvements in range (there definitely is some he says) he installed it in all his guns and has been delighted with the results. At the very least it definitely sounds like the way to go on a gun you're mounting or replacing a hob up in.

Your friend is right but What kind of barrel does he have? We have done dozens of R hops and the ones that are done in Steel barrels tend to be much more impressive. Im my guns I have seen an Increase in range of about 50-75 feet, and that is DEPENDENT on the gun, Barrel and hopup.

thanks elder90. I called today and couldn't get through busy no doubt. I would love to get a pair of BAR's through your tech team!

I too have a .30 cal that I would be willing to ship if got the gold touch!

GIve me a call tomorrow Paladin, Ask for Tanner and I will talk to you about the R hop.

I am in from 3-7 Mountain time.


Also some good news, the owners of Fox are at Shot show right now trying to work out a deal with ICS to get As many Garands in as possible to do a Review before it comes out. I will keep you posted (Sorry it off topic)
