He's using Psionic Upgrades (italian company that presented the R-Hop as the latest technology super duper upgrade, when in reality it was already around 10 years ago) pre cut patches, he has just to glue them, slap a flat rubber on top and replace the tensioner. Afaik he hasn't installed anything yet and for our testing he used a pre assembled set (patch, barrel and hop unit) from PU themselves.
I reckon €85 is a bit too much when the kit costs 20 and can be made for pennies and some silicone tubing. Take into account umbrella armory too, they offer a Maxx hop unit, a nice Prommy barrel and the R-Hop fitted and tested for €160. https://umbrellaarmory.com/collections/r-hopped-barrels-1/products/umbrella-pdi-6-05mm-r-hop-inner-barrel?variant=29676572704881 (breaking that down it's €70 for the chamber alone, the PDI 6.05 goes for roughly €100, so the patch + installation is basically free)
Still, my €11 AEG MR-Hop seems to be giving the same exact results in sending .32s way over there at a fraction of the price (while still retaining most of my sanity because lol @gluing shit on the barrel).

r-hop is a pain in the ass, much easier to just use a maple leaf offering.
