R-Hop Installation Service
[17417]
Free Shipping for orders over $149 No Coupon needed
The R-hop is a modification where a rubber/urethane/silicone patch is inserted into the hop window on the inner barrel of your airsoft gun. The patch is meant to fit flush and conform to the radius of the inner barrel. By applying a symmetrical backspin over a longer distance, without providing any downward pressure in order to reduce the amount of contact the bb makes with the surface of the inner barrel. The result is a much more consistent hop trajectory and increased range. When paired with a high quality inner barrel, it makes for an impressive increase in range, consistency, and accuracy output.
This service includes all labor and materials to perform the modification in any applicable airsoft gun. This includes patch, new bucking and any modifications to the barrel window.
NOTE: Due to the elasticity and reset speed of the materials used, in some high rate of fire guns, using full auto can result in slight loss of hopup trajectory.
Package Includes: One (1) R-hop Patch, One (1) New Bucking, Modification and Installation of R-Hop Patch
Please Note: The R-Hop modification is NOT compatible with Miracle Barrels, Prometheus Delta Strike Barrels or Gas Blowback Guns.
Please Note:
- We require at about 10 business days to complete upgrades. This is an estimated time ONLY; some jobs may finish sooner, some may take longer.
- R-Hoped barrels work best at a velocity of 380+ FPS. It is also recommended to use .28g BBs or heavier depending on the final velocity output.
- $65 Fee only covers one (1) Gun
- Installation work may take longer than 10 business days to diagnose and repair.
- If you purchase this service, and plan to send your airsoft gun through the mail, please call Airsoft GI during our business hours to receive shipping instructions. Our contact number is (909)869-0671, and our hours of operation are Monday - Friday 9A.M. - 5:30P.M. PST. PLEASE DO NOT ship your gun to us without calling.

I won't be here to preach how R-Hop _ Everything else as I haven't truly been able to test how much better it as as any tests I can offer is invalid due to possible bias or error due to external forces.
I will say though as a pro and I'm sure isn't biased, the R-Hop is more durable than most other hop-up bucking. This is due to it hopping against a rubber plastic vs rubber bucking. I've blown through 3-4 flat hops, Prommy Purples, which cost me 60-80 dollars respectively and so far shot 20k rounds through the R-Hop with almost non-existant wear.
R-Hop may or may not be for you, it may or may not increase your accuracy groupings, it may or may not increase your range. But at the end of the day when I can look at my hop-up and see hardly any wear, I have to say I am a winner. Installing Flat-hop is easy to do, but when you have to replace it so often I feel it is more a hassle.
The installation here is done by a professional, the bucking cost about 20... the rubbers cost 15 dollars = 35, for 30 dollars for a quality installation and never having to replace the bucking, for a long time at least, I would say the price is right.
Pros:
- Price is right for quality installation
- Durable vs other bucking
Cons:
- No Gun for 2 Weeks
- Placeholder to reach 30 character minimum

I purchased this for my AMD-65 that I acquired back in September for my birthday and I must say that the performance on it is superb! I can easily reach out and touch people around 200+ feet, which is perfect considering that I play mostly outdoors. I bought the service with the gun so it only took around a week longer than it usually would have to ship to PA. I would recommend it to anyone who wants to have a long lasting, high performance hop-up in their AEG.
Pros:
Quick shipping time considering tech work was involved
Excellent range out of my AK
R-Hop is durable
Saves me the hassle of taking apart my gun
Cons:
A little pricey (but if you can afford it, it is well worth it)

Krytac Alpha crb was upgraded and turned out amazing no cons!
Pros:
They did outstanding! They did more then just the R-Hop! I paid extra for them to also include a madbul barrel and i have absolute no regrets! I just went out and played at an event and i did amazing with it! usually my bb's would start to drop or curve away at about 100 ft. but when i played with it upgraded it was like a whole new gun! I was averaging kills at 200ft!
Cons:
There are no cons at all. super happy with the purchase and if your thinking about doing it, you should!

Would it be a good combo if i were to use this in a 500mm ORGA Magnus 6.23mm widebore inner barrel with parts for better compression (i.e. non-ported Cylinder, double O-ring Cylinder head, steel tooth Piston, and a O-ring piston head), a high torque gear set, a M150 spring, and converted to semi only?

Included Bucking
I noticed in a previous question that the included bucking is a Madbull Blue, however I do not like the reviews/looks of bucking and was wondering if I could have you guys keep the current bucking (KWA SR10 2G Bucking) and still install the R-Hop. If there is a drawback, please tell me. Thanks for your time.

It really depends on several factors, namely the FPS on the gun, the barrel diameter, and the bbs you're using, but assuming 400 fps, a 6.03 barrel, and .28g bbs, I'd venture to say over 200 feet.
