Looking for a Hop Rubber, Nub and Nozzle

[Noob7_0]

In the quest to optimize my G&P M4 I have now come to my barrel, hop up and nozzle. I currently have a 10.5” barrel with a 363mm inner which I will conceal with a suppressor. I have a Modify hop up with the Modify rubber. My unit doesn’t use a nub, forgive me I don’t know the nomenclature but the arm on the hop up that pushes the nub has a bump on the end in lieu of the nub. I have a replacement arm to receive a new nub.

I know I have compression between my piston and cylinder (type 2 cylinder) but I need to double check the cylinder to air nozzle. I have checked my nozzle-hop up seal by shining a light through the feed tube on the hop up to check the amount of light entering the barrel and there is a small amount so my nozzle isn’t sealing well to the hop up.

I have seen lots of discussion about “getting a good seal” and “get a good rubber” but I don’t know which products to look at and what will be efficient with my Modify hop up unit. What rubber, nub and nozzle should I purchase? My intent is to run a M110 spring for outdoor with .28s (minimum) and an M90 with .20s for indoor.

You can improve the nozzle/hop-up seal by sanding some material off the front of your tappet plate such that the nozzle will sit more forward.

I used to like Modify hop units and a lot of users here rave about them, but I've consistently gotten 20-40fps less on a Modify hop-unit - all other things being equal. The unit does give a very consistent FPS and I think a user examined the hop unit and declared that the ridge where the hop rubber's lips rest is cast at a different angle and thus leads to leaks. I haven't looked much beyond that and now I just use G&P hop units with good results.

Depending on how old our G&P is, the nozzle should be of decent quality (machined aluminum with o-ring) so I don't think you need to replace it unless you want a fancy red one. Lonex POM nozzles have been pretty good to us simply because the POM material has more lubricity and helps the hop rubber lips to slip over the nozzle better.

Take a look here:

We only stock setups we would use and recommend. In order of difficulty of installing and increasingly good results:
Lonex soft rubbers
PDI W-Hold (I'm only including them after the standard hop rubbers because the rotation of them needs to be just right or you'll get left or right curves)
REAPS
Flat-hop
R-Hop

I mean, the sky's the limit, just depends on how much time you want to screw around with it.
