I’ve been using this in my dmr it’s plastic material not rubber so the adjustment is very slight I tiny movement ether way makes a difference but it seams to keep a better consistency I’m using a r hop so the hop stays firmer in the barrel can be a little fiddly to set up I would recommend using a r hop or maple leaf rather than a standard hop with this nub as it pushes the sides for better coverage and with it being plastic you need the hop to flex as this can’t if you get it set right you can get it working very well but it is harder than a standard hop nub in both senses

They're a great idea and makes sens e to follow curve of the bb. The issue is then need to fit in a hop unit, They're tiny! Even with pro purples the soft rubber doesn't follow the shape of the 'H' I've tried these in my G36c & MP5K PDW. They work but as to being better I didn't see better results on my chrono. Maybe they'll yhe rubber will settle into the shape in time. Maybe... oh and they're slightly too wide for either hop. Just sand a fraction off each end. 400+ wet n dry.

had to sand the ends down to fit in two different hops but no biggie. They're tiny, whether the hop rubber will fit the curve - jury is out, due to the size and the thickness of even Prometheus purple i could not see the curve in my G36c or MP5K PDW hops. Does it work? Yes, as a hop pressure nub it works, wound my hop units right back to almost zero but it works. Is it better than other types. IMHO not really noticeable difference. put 500 rounds throught it and no problems. im hoping the rubber assumes its curve after time. Time will tell i guess
