matas17 Posted July 26, 2018 Share Posted July 26, 2018 So im in need of new hop unit/hop rubber and a nub. I am not sure what would be best combination for 326fps gun with 0.2g. Anyone can recommend something who has more knowledge in this. Thanks Link to comment Share on other sites More sharing options...
Mostly Retired Moderators L3wisD Posted July 26, 2018 Mostly Retired Moderators Share Posted July 26, 2018 The first thing you should do is up your BB weight. With a new rubber you could / should be fine on .28s. One of the most popular rubbers is the Prometheus purple (you'll see this called the "Prommy purple"). I've got one and it's fantastic. I'm going to start keeping a spare in my case too. Hop up units tend to be finicky. I've got a Prowin and it works fine for me. Some people have guns that don't agree with the Prowin. It's trial and error in afraid Try a purple rubber in your gun first with heavier BBs, leaving the hop unit standard for now and see if you're happy with that is my advice.

My main rifle is KWA RM4 ERG and the hop unit is bit of a hassle, since its really tight and honestly. its hard to slide barrel with hop rubber on it. Its so hard that the barrel literally slides through the hop rubber and pushes it back past the space where hop rubber is meant to sit. I tried Prowin and whenever i get everything done, it feels bit loose on the inside no idea why Link to comment Share on other sites More sharing options...

Supporters ImTriggerHappy Posted July 27, 2018 Supporters Share Posted July 27, 2018 Forget the Prowin and look at the maxx hop unit. It is far better and doesn't have the same QC issues. Link to comment Share on other sites More sharing options...

EvilMonkee Posted July 27, 2018 Share Posted July 27, 2018 Prowin won't fit in an ERG, believe me I tried. You are pretty much stuck with the proprietary KWA hop unit. Re rubbers, the best that actually fits is either the Guarder Clear or the Madbull 50, both will need trimming down to the correct size. Re hop rubbers in general, I have found the G&G Green to be superb Link to comment Share on other sites More sharing options...

Re hop rubbers in general, I have found the G&G Green to be superb it does fit once outer barrel is filed down properly, Believe me i done it to fit any hop unit i want. and i have 2 uppers 13.5'' and 10'' both are filed down to fit any hop unit Link to comment Share on other sites More sharing options...

Extremely well made with good tolerances. It comes with a couple of arms to suit your preferred hop and nub combo and there is a tracer version as well. They have even made one specifically for the ICS Cxp range. Haven't had my hands on that version yet but hoping it is just as good. Link to comment Share on other sites More sharing options...

Try skirmshop uk for it. Might show out of stock but they will get it in for you and at the same time you will be supporting one of our own as he runs it.

Arwen Posted July 30, 2018 Share Posted July 30, 2018 Newbie question alert... I've got one of these hop units in my Recce just now. *Unit with the adjustment wheel on the side Can I replace it with a unit with the adjustment wheel on the back? Like this prowin M4 one? There seems to be plenty of space around the unit when it is in the gun.... but I don't know if am just not looking at it right: Link to comment Share on other sites More sharing options...
E21A Posted July 30, 2018 Share Posted July 30, 2018 Yes, should fit just fine. Link to comment Share on other sites More sharing options...
