I would like to hear from a few of you guys on this before I plan to buy it!

I have been hoping for a tighter grouping for my new DMR build. Now, my questions are as follows...

1. If I am going to purchase a r-hop from HSA, which would best suit me for a G&G M14 EBR? I am pretty good at modifying, however, the easier and less-likely I am to mess it up, the better.

2. How hard have you found the installation to be for an r-hop? Do you have any tips outside of the guides that are offered?

3. How dramatic of an increase have you seen in the grouping of your shots, or rather, the overall accuracy of your shots in general?

Thank you for your time everyone! I'll be waiting for your replies. op:

1. The regular R-hop is the easiest to install and will suit your purposes well.

2. It is very easy, it only takes about 10 minutes to do once you have done a few.

3. It is fairly dramatic, maybe better groupings by half or thereabouts.

My suggestion is to get the ir-hop because of the better temperature tolerances, but it doesn't matter too much. Also make sure you use at least 400 grit sandpaper to sand the channel and try to get it the same shape as the bb. I wasted an ir-hop because I accidentally sanded the channel too wide and it made the bb swerve left. One more thing, replace the hopup arm nub with a bit of nerf dart foam. It was suggested to me by Cheese and works great.

also check out Rezzo's thread in the rifles&parts section, he does a complete install and test fire in a 16 minute youtube video.

Also use a very very very very sharp cutter.

I'm the only guy who's ever not have HS5's R-hop work for me (bad installation likely). But luckily I found someone in HK whose using it and getting pointers from him on installation.

Excellent guys, thank you for all of your input!

@Cheese: By regular R-Hop do you mean the R-Hop/IR-Hop, or R-Hop/Z-Kit?

@Master: Would the IR-Hop really be necessary for an AEG? I won't be playing much in temperatures anywhere below 20 degrees. Even then, I only plan to play maybe 5-6 cold weather games, so I am not sure if it is necessary or not? Also, in regards to the Nerf foam (this may also be directed at Cheese)... How much/how little is enough foam? Should I cut it to the approximate size of the existing nub, or should I cut it larger due to it being easier to compress than the rubber nub?

Thanks again guys!

I cut mine to the thickness of the regular nub but to the length and width of the r-hop patch. If you don't play too much cold weather then the ir-hop really isn't necessary, but like I said, it just ensures the weather won't change it's characteristics. It's sort of like getting that extra tough material for something you build, even though you know the normal material will probably stand up, you just want that extra strength. I think it is a good idea, but get Cheese's opinion too.

If you are really worried about how to install it and what to use, I'm pretty sure Cheese does regular r-hop installs (as in not er-hop) although I only see photogenic r-hop install on his site.

I call it the photogenic R-hop install because I install it for those who want it to look pretty for pictures. It takes a little more effort but it looks really great. It's the same thing.

I cut a little bit from a nerf dart, tested, and then just kept doing that until I had the right nub. It will be slightly larger.

I mean the R-hop/Z-kit/IR-hop. I personally like the IR-hop because I live in AK, but honestly, the regular R patch is better if you don't plan on playing in the cold. Even then, it really doesn't affect it too much, but it's all up to you.

 

[TheTJ]

Sounds great guys, thank you. I'll just wing it with the guides and post my results!

What others said. One thing I might add is that the Z-kit made it incredibly easier for me to install the hop because I basically had three different cuts that I could try. One fit perfectly on my Prometheus 6.03 barrel (VSR cut for my Tanaka M40A1) so I did not have to modify the legs or the outside of the hop. I just had to file the inside with some sandpaper because I was getting a lot of overhop (consistent, but still overhop) with .43g.

Also, by getting an IER-hop Z-kit, I got the amount of a total 6 regular IR-hops, when cut..this means I have one spare for my Tanaka M40A1 and maybe the others will fit my G&P WOC GBB or I might get crazy and install one in my KSC P226 PTP

This is my R-hop video CM was referring to (thanks! Shameless plug )

Just emailed HS5 for for a purchase order. Grabbing the IER Z-Kit and a Barrel Lockdown Kit. Wish me luck when it arrives! =)
