So in your video you suggested crazy glue-ing the patch to the barrel window. In the barrel I tried it on (madbull 6.03) , what seemed to be the closest fitting patch still raised up slightly when I inserted the round rod shown in the video, thus preventing me from glue-ing both edges. Like the old video showed, I used some silicone to fill in that space and then sanded the top, but I was concerned that the patch may have been lop sided off to one side or the other when I silicone it in place, so when I didn't have good results I got discouraged after my second failed attempt... Any suggestions?
I should note that I did also try sanding the inner channel as per the traditional way, and upon disassembly I noted that the flat hop I was trying was to big for the hop up window. So many variables here. This would also be much easier if I didn't live in the city, and could just go out in my back yard and test it any time I wanted...

So far, have shaved and sanded the bucking, Was worried about tearing it but was able to do it. Over cut the r-hop so just sanded it down to fit. Two pin head drops of super glue to hold it back in place. Just waiting for that to dry and I'm done. Hopefully it turns out good. Still worried on it tho. When the barrel goes back into the hop up.

The r-hop goes on the top right?

You're going to want to sand down the top of the r-hop patch so that it's flush with the outside of the barrel before sleeving your bucking on.

I know this is a older post, but I was wondering what patch people used in Prommy barrels. I tried the medium barrel, and its seem to fit the best, but still overhopped with .25g bbs

you have to be extremely lucky to have a barrel that you just put the patch in and go.. so far I've not found a barrel that any patch fits perfectly in terms of barrel intrusion. Also after sanding it to fit with 0 intrusion and being able to drop a bb down the barrel, once installed that sucker overhops everything to the moon, so I've had to sand the inner radius on every install I've done so far. This is where patience and the futzing come in.. you need to sand, assemble, test... pull it apart and rinse and repeat till its' right.

YMMV. I've used both the middle and deepest patches for Prommy.

Oddly I've been really darn lucky without having to sand the inner channel on any Prommy barrels.

If you're over hopping you need to make sure the outer curvature is sanded flush and your hop sleeve is also flat.

yup to both. still overhopped in the v2 I installed prior to nightfall... the patch was flat with the outer and no protrusion inside, but when installed into the hopup, the hop was always on... I aggressively went at the inner surface using the installation tool and some sand paper, we finally got acceptable results. We were using a prommy bridge nub which to me appeared to fit very tightly into the window, maybe too tightly soo maybe it was jamming in it and not releasing properly when adjusting the wheel.

I did another v3 the night before we left and it's shooting beautifully, though I sanded the fuck out of it both surfaces to make sure there was good clearance. This one was set to use a standard cylindrical nub.

Just so everybody is clear and has a good idea of what a perfect R-hop install using a Z-kit looks like, I threw this up really quickly right after finishing an install for a client.

Perfectly-installed R-hop - YouTube

Hope it helps everyone.


If you have ham hands, email us at sales@airsoftstore.ca to inquire about our R-hop install service. Now that the summer season is over, we have a bit more free time to do the smaller jobs.

Alright, I'm bumping this up because we've literally sold HUNDREDS of Z-Kits but have yet to see any "in the wild".

So what gives guys? Are people having difficulty installing it? Does your install look too mangled to show and tell? We're here to help.

I'll start - this is a #2 patch in the bonding stage on a Prometheus barrel with the new Installation Aid (V6)



On another note, we've been asked whether or not the R-hop is maintenance-free. And the answer is - yes, for the most part. I have over 50,000 rounds in one of my R-hop barrels (through 2 seasons) without the need to clean the patch.

But if you do wish to clean it, do NOT use any solvents to clean the patch, a simple dry Q-tip will suffice to remove any BB residue from the rubber surface. A photographer's lens blower will finish up the job. Compressed air (duster gas) is pretty dry and should be avoided.

Also, when cleaning R-hopped barrels, make sure that the hop-up is turned completely off so that you do not shift the patch around in case insufficient adhesive was used to secure the patch (which should be rectified anyway).

I've been partial to Loctite brand CA glue lately, but in the past I basically just bought the first thing I saw at the store. The actual adhesive used really doesn't matter, the key is the consistency of the adhesive at the time of application and the actual method of application.

I tried crazy glue with no luck whatsoever. It didn't even bond to the Promy barrel window. Also, the edges of the patch didnt sit well on the edges of the window, no matter which of the 3 patches I tried. Do they need trimming? If so, how?
