R hop or flat hop mod..

Has anyone here done the flat hop before? Please tell me something more about it.

I want to install an R hop in my M28 but there is no freaking way I wanna take apart my rifle about 20 times. I just dont wanna,lol.. So the next best option is either R hop my Sr25 cause the hopup is much easier to get to.. then when its perfect, take the barrel back out and put it in my M28? Would it be the same setting or would the different hopup and bucking make things different?

Also, since I just dont wanna fool with an R hop so much, would the flat hop just be the way to go?

I guess its safe to admit I am getting lazy in my old age,haha.. The R hop just seems like too much work! I dont wanna fiddle with it that much. I'm already getting 250ft or so with the stock bucking and excelent accuracy since I shimmed the hopup arm and did the Tdc.. Or should I not even bother since its already a pretty awesome rifle?

No videos, it's just the nature of the beast. Like Luluk described, you have to push the bucking into the barrel. This causes excessive wear on the bucking, and while it will last for a time, and work well, eventually, it will tear, and you'll need to replace it. There are other reasons, but that's the biggest issue in my book.

Check out They have the HS5 R-hop installed Prometheus barrels. However, they are all AEG cut, not sure how that'll work for whatever guns you guys have.

And you could always send the rifle or hop up assembly off to have a tech install the r-hop for you.
