thanks so much guys! They are a CA and g&g lr300. I have an airsoft pro cnc hop unit for my g36 and I think I'm gonna get thier m4 one... It's all these rubbers, buckings where I just get lost. I hear loads of stuff about r-hops but also that they are better for higher J guns. I will investigate the prommy ones. my g36 hop up is OK, (stock everything but unit) but I can't get it to overhop, leading to me think that it is probably underhopped... cheers again, it's appre...

Here's another brainscratcher: try and get the right 'rubber hardness' for your fps. I'll need to look it up but it's along the lines of 45

° for sub 300, 50° for sub 350 FPS, 60° for sub 400 and 70° plus 400 FPS and such. Don't quote me on the number though, no-one is very clear on that. It even depends on your ambient temperature since that also influences the hardness of the rubber. ANYWAY: I'd say try a few of premium brands

R-hops are indeed superior...

Thanks again. Gonna go for Prometheus / Laylax black and see how I get on. Cheers
