Who wants ER-Hop? YOU DO.

[Minerva]

So people HS is offering a deal for people.

If you want in, know there will be a deposit so once you commit you're in.

We are making a group order and you will get an ER-Hop made and installed for you

What you get:

Prometheus barrel
Hop cut for ER-Hop
IER patch (good for cold weather places like Oregon)
The bucking I think we determined to be a Prometheus red bucking, seeing as some people will use these for higher velocity set ups and you need a good seal

All of it will come pre-installed and be able to shoot anything under a .66

Total cost will come to $169 for the entire set up.

I know it sounds like a steep investment, but trust me, it's worth it.

Deposit will be $60 and the $109 will be due upon completion.

You can try your hand at assembling it yourself and it will cut costs down to $43 for the deposit. It will not come installed however.

You all seriously need to consider this.. If you haven't tried R-Hop before, this is your chance

If you're interested go ahead and drop a post HERE

We need more people so we can get the ball rolling on this. If not, it won't happen, so get everyone on board

Here is what it looks like

aside from your promise that it is awesome, please elaborate on how this is better than a standard hopup. evidence would be cool too.

i'm interested, but i want some proof on those magic beans.

Ok apparently I missed something. What is an ER-hop or EIR-hop and what makes it worth $169 ?

[Minerva]

Ah I see. Hold on allow me to gather a few resources..

[Minerva]

This:



Is an R-hop.

It works off of the principal that instead of using a single point contact such as the mound on the inside of your bucking to create spin on the BB, you need something that is concave to the BB to create proper back spin without axial spin to throw it off.

The point of contact is also MUCH MUCH larger creating much more hop so minor hop adjustments will have a HUGE difference..







This R-hop patch sits inside the hop window so the bucking actually never makes contact. Therefore you need to shave the mound off of the inside of the bucking to create a flat surface.

This concept all came as a result of some R&D after taking a look at the G-Hop and working off of that concept of longer contact.

G-Hop concept:

If you still need more information on the evolution of G-hop to R-hop in can be found in the Quasar thread here: http://forums.airsoftmechanics.com/inde ... pic=3603.0

Please note that that G-Hop video was done on Japanese velocities..

if you are thinking about seriously marketing these you should get two identical guns and install your design in one and leave the other stock, then take them to events. having a side by side comparison to show people what their $170 would get them would work wonders.

i get the idea now, and it makes sense. id like to personally see one in action before i dropped that kind of money on it though.

That is pretty swell. Can't throw the monies at one, but I sure like the idea.

I'm not marketing these, I'm just trying to generate an interest so we can do a group order from Hunterseeker.

It's not my design either I guess it can be originally gungineer's G-Hop design taken by Hunterseeker, and developed into the R-hop. It works kinda like an SCS should, but better because you have direct contact and it is flexible to a BB being pushed over it.

I have one in my G36c and it's getting out to 200 feet.

Mind you that video had a gun shooting well below 1 joule too and was getting somewhere around 160-180 feet..

The designer kind of has a thing against posting "proof" videos due to the massive amounts of flame and haters/stupid people roaming the internet. I'm sure I'm not the only one here who has messed around with the R-hop though. Hell I'd bring a barrel and R-hop and show you all the concept and how to install and whatnot but I'm down in California now

[Minerva]

If you guys are also interested, seeing as this is a new concept to you, you can try normal R-Hop. It isn't that difficult to install though you do need to be technically minded to do so..

You can purchase the patch here: http://hsarmory.webs.com/productsandservices.htm

It's a tedious job I have to warn you... But well worth it. And at 12 dollars it's pretty cheap too ^_^

I stopped caring about the performance of my guns long ago.

[McNair]

That is quite obvious.

So basically...you mill out the barrel, drop in another longer piece of rubber...and then slide the bucking over the original piece of rubber....

Ok, I have the milling machine...it looks like a piece of rubber tubing that is cut to size. If I can find the tubing...I'll make one.

Soooo....anyone that can find the tubing I'd need will get my undying love....especially Josh.

Seagreen it's made from some strange material. I think he orders it from Taiwanese factory making them (or so the baggy says) You can order a pack of 3 for $12 shipped so idk why you'd need to buy your own..

Also it's sort of like that.. I did mine with a dremel and it turned out dandy.

You also have to invert the bucking, shave or cut off the internal mound of it. Then you cut the circumference of the patch and sand the sides down to fit. Then you place the patch in the window and see if it fits flush. If all's well, then you un-roll the bucking over the patch and test fire it. A little bit of hop goes a LONG LONG way. If you are over-hopping too bad you have to go and sand down the inside of the patch (uniformly) and re-place it. Once you have it shooting right, put a TINY TINY TINY amount of glue in the corners of the hop window and place the patch there. Then apply a thing layer on the patch and roll the bucking over.

In my opinion, it helps a lot to create a square shaped nub for this too, because it helps more uniformly distribute pressure in the ER version. You can use some scrap sorbo or something you have laying around..

It sounds really easy, but it takes a few tries to perfect it. It's a really cool innovation for the DIY'ers but too in depth for the drop in people.

The reason he is selling the barrels as a pre assembled set, is a lot of people are afraid to go hacking up their hop window with a dremel. One mistake, and you just scrapped one . So from a business standpoint, a drop in works very nice

I think the longest purported distance was 380 some feet with an ER-Hop installed into an SR-25 shooting somewhere around 500 fps.. You'd have to ask Age though. I think he has a video of it floating around somewhere..

Although I agree that $12 is inexpensive...what's a project if you can't resource all the parts locally? That's the fun man!

That being said: I'm looking at this more in terms of a bolt action rifle...to help stablize heavier rounds. The current hop-up buckings in AEG's function well enough. The bolt-action hop-ups are usually finicky.

Seagreen have you thought about LRB's?
