Update time… sort of.

Its been a week… I have still not gotten an official, "Yes, I will redo the install." I have only gotten small hints…

Since my last post, Tony has been 100% unresponsive to my emails. Even prior to that, he only answered emails as to why it could have done that, nothing to do with sending it back.

Everybody I know thinks I'm crazy because my KJW M700 curves left and right, which is apparently "alright, even if its a sniper rifle"

Story of my life the entire time I owned mine.

Feel free to contact me if you like. I'm working with Todd's KJW-based Mantis and getting 180yds out of a sub-4 joule setup on less than half of your hop up/BB contact patch. ER-hop is totally unnecessary and overkill for what you're trying to do, by the way.

I'm giving Tony until tomorrow before I call him for a 1-on-1 talk over the phone.

I did see your posts on the Mantis, I followed that all the way. You were using .66g bbs, which contributed to the awesome ranges. I also noticed you said that accuracy was not perfected yet. What do you plan to do about that?
Do you think that the ER-Hop was giving the bb too much friction therefore reducing its velocity and range? Not going past 200 feet seems odd for a system like that. As I recall, you are using a simple R-hop design?

Sort of. We haven't TESTED for accuracy yet, as in we haven't hung a target out there at max range. We're still dialing back some over-hop so once we've got the hop up tuned we will be working on adding some more power back in for Gunner. He doesn't skirmish with it so a higher energy/MED doesn't affect him negatively. It is actually cut down from a normal r-hop patch length and is only about .220" long.

I don't want to speculate on why your system is sub-optimal, but I DO know that I can get 100 yards or more with a plain vanilla Nineball bucking and 2.8 joules using the 'defective' BBWarz .43g BBs.

Whats actually funny…
I can safely conclude that range, prior to the ER-hop, was never an issue. I've got a 500-foot pond in my backyard, and 300-foot natural range, the bbs have always flown 300-400 feet without issue, but sometimes over-hopping. It has always been the accuracy that has been sub-par.

Last night I got really determined and decided to do something that I have never attempted before, and that is a flat-hop. I've got a bunch of stock parts from the KJW, I've owned several. I didn't want to hurt the fragile setup I have now because it didn't curve (but has inconsistent hop) so I decided to use stock everything. This means the stock plastic chamber, stock brass barrel, stock nub, and the stock bucking flat-hopped. Being my first time flat-hopping a bucking, I did a sub-par job, hell I probably double-bogied it… prior to installation I did notice a little piece was hanging out on the left, so instead of fixing it my lazy self decided to let it be and assume there would be left curve.

I can finally say I am thoroughly impressed with the performance. I mean, shooting 230 feet accurately was a pipe dream before… And yes, I was correct about the leftward curve, my fault entirely.

But there is one thing that has bothered me since I shot the rifle and hour ago: I'm using a stock barrel with a 6.10 bore, and who knows how good the quality control is on that. Why has this bothered me? I never feel satisfied until I know why something happens the way it does. Popular belief has it that stock barrels are bad for accuracy no matter what… I've been thinking about the theory behind using wide-bores for polar star rifles, do you think this could be the answer? I could use some input here…

Bobcat:
Hopefully the Tech will warranty his work and the parts.
If he does not, then that is on him.

In airsoft and tech work, "stuff" happens.
Maybe it was one minor thing that went wrong and thus the domino effect ensued.
Give the tech a chance to make it right.

Also understand that everything about Hop-up work involves fine tuning and testing. Generic filing of the Patch and shooting out to 50' in the back yard is a blue-print for a terrible R-hop install.
A lot of professional airsoft techs do lousy R-hop installs, even some very distinguished techs.

R-hop can be a difficult mod to get right.
It simply takes fine tuning and thorough testing, that most techs really do not have the time for nor proper place to test, before sending the finished product back to the customer.

It just ticked me off that I spent $200 with the only HS5 Certified tech to ER-hop my barrel. The tech wanted to charge me another $15-20 just to have it reinstalled, plus two way freight charges along polar ends of the coast.
Considering Tony is the only HS5 certified R-hop tech, I'm sure you're right, Vanevery. I don't know what kind of test setup he had.
I will tell you I was surprised to hear he finished the job literally overnight… (Shipped Tuesday, arrived Thursday, done by Friday, shipped back Monday, arrived Wednesday)

Because I still have the ER-Hop products (chamber, barrel, nub, etc.) I was planning on going to McMaster for the tubing, not making the mistake of spending $21 on two patches, then having Tony take the extra… And trying to reinstall the patch. If it breaks, hey, I got 10+ feet of it…

Thanks for the input, Vanevery

I hit you up in another thread, but I wanted you give you a look at my last install and offer to do yours for free in exchange for a favorable review (if, in fact, you find my work acceptable. Hopefully it exceeds expectations!)

This was done on a Prommy Delta Strike barrel. I did the install for sgtwilliam and, because I was so amped about it, used it in my weekend game for "testing purposes". Mwa ha ha. It's cool though, he's in Norway, what's he gonna do about it?? :hehe:

Seriously, though. I put it in my PolarStar, 475 fps with .20, and I was firing .32 EliteForce bb's. It wasn't quite reaching ranges that my 540 fps APS2 gets, nor quite the accuracy, but really darned close.

The offer stands, though. I'll do your install for free. Mostly because I don't like HS5. At all. I'd rather do yours for free than have you pay him for anything.

You can do mine for free ;D

Jks but that's a pretty good deal

 

[bobcat]

Truth be told, I don't like HS5 either… They over charge way too much.

Paid Tony Zito of HS5 $160 to do an "excruciatingly difficult" ER-Hop, and an extra like $30 because it was a steel barrel…
Later that month I spent ten minutes with a metal file, vice and another steel barrel, did an ER-hop cut just fine… it made me angry

As for your offer, That is just awesome. I cannot believe how nice people are on this forum; I've gotten several offers from other members here about this thread, its just fantastic.

I'll have to consider the offer, basically its either I give it a go myself or I send it to you… Maybe I can attempt an R-Hop on my other barrels… (AKA, leaning towards having you do it…)
Do you have the material available, or will I have to supply?

Thanks again!

 

[Shifty1016]

I have everything on hand.

If I charged someone $200 for any tech work I'd have to sit and contemplate my life. Just send me the barrel and hop unit and we will be set when I send it back I will include hop and nub material for you to try more on your own.

Ya, HS5 said a few things about me, personal stuff, because I started cutting in on his share of the r hop market. Then I realized that I too was being a vulture, even by selling the material way cheaper than him. Now, I'd rather just give it away as long as that takes business from him. Plus, by now the material source is quite well known anyway.

Hi guys,

Just finished reading all threads and a lot of good info. Bobcat sorry about your set back. Hope you get it right. I just bought a KJW M700 from evike since the had it this past weekend for only 161.50. And Bobcat I've read your guide about a dozen times already. Great stuff.
Shifty1016, once I get my hands on my M700 I would like you to do your rhop on my 700. Just let me know what to do.
