R hop does not involve any accuracy sacrifices.
It looks interesting but as a few people have said I'd need more info before I believe the 60m range claim.
I would be interested in putting one in my M249 to give that some extra harassing range if it turns out that you sacrifice accuracy for range as the vid seems to suggest and if people find they get accuracy too then I'd probably stick one in my nbb socom as well.
R-hop, if anything, should be increasing the accuracy due to long contact patch.
You can see that the grouping improved drastically when he tested the AEG which should have longer barrel(and perhaps also higher quality).
So...if this one fails, go for a real R-hop?
