Firefly Hop Up Rubber

[LocoYokoPoco]

Hey there,

So after reading a lot of buzz around firefly hop up rubbers, im considering purchasing one for my G&G M14 DMR setup. However, I'm not entirely convinced that it's worth the price tag. I've used hop up rubbers from systema, guarder, modify, and prometheus, but I keep going back to the stock G&G green because it performs so damn well. Will the firefly really be worth it?

[ILLusion]

The Fireflies have a double nub bucking, which none of those other mentioned hop up rubbers have.

The only other hop up rubber I can recommend over the Firefly hop up rubber, is the PDI W-Hold. They're a bit more durable, and they perform a bit better... and best of all, they're cheaper. I've been trying to get my hands on more, but they've been sold out at all of my distributors.

It makes my sniper rifle a laser rifle. And I with the one in my M4, I was able to range a few other sniper rifles.
Absolutely definitely worth the price.

I didn't believe it till I seen the difference it made in my gun. Took me a few hundred bbs to break it in then all of a sudden like he said... laser

Yeah, the Firefly isn't a bad hop up rubber. In fact, I have it installed in quite a few of my pistols, bolt action, and AEG's and I think they're absolutely fantastic. They're very very accurate and very durable. I like the PDI ones more, only because they yield a slightly higher FPS along with the dual nub feature, plus the nitrile construction makes it more resistant to chemicals found in some oils and greases. They're still fairly new, so there's no long term results yet, but I'm liking what I see, especially at that price.

Hmm, I'm very interested in the PDI rubber now... Please let me know when you get some in, I would love to try it out.

As for the firefly rubber, I've heard of quite a few problems with air seal as well as durability. Can someone testify against this?

Also, what nub would you suggest to go with the rubber? SCS, H, or standard?

I have a feeling that this conversation isn't gonna end well for my wallet :P

I personally haven't had any durability issues with the AEG version of the Firefly hop up rubber, and the air seal seems "good"... it's on par with Marui. It offers no noticeable improvement for air seal.

On the other hand, the PDI ones do offer a bit of improved air seal in the range of 1-2% fps increase. It's more noticeable if you convert a gas gun to use this.

I'd actually recommend the Firefly nub... because it's a rubber nub, it offers more give than the hard nubs like what SCS and the Big-Out H-Hop offers. The flexibility in the give will prolong the life of the hop up rubber itself.

But what about consistency? Wouldn't a harder nub give you more consistent hop?

[ILLusion]

Not necessarily. I prefer flexible nubs, because the pressure remains more consistent against the BB, as there are two levels of flexibility (the bucking and the nub) that will affect the BB, whereas if you have a hard nub, it's just one level of flexibility (the bucking), backed by a fixed (solid) nub. This means a BB sized at 5.95mm will receive the an increased amount of pressure as a BB at full spec of 5.96mm, when it should actually receive a variable amount to deal with the difference in tolerance for an equalized pressure. A flexible nub will allow for a greater range of variation in flexible pressure, whereas a hard nub will limit it.

Anyways, this is just my opinion. I'm not an engineer and have no quantifiable proof of it. I've personally had good experience with SCS, H-Hop, and Firefly nubs... I prefer the Firefly nubs for the durability aspect alone, as it gives the rubber more give.

[LocoYokoPoco]

I think I'm sold on it. Only problem is it's out of stock on every retailer I've looked at

[ILLusion]

That's another reason why I started stocking the PDI ones... the Firefly ones are too hard to keep on the shelf. They fly off too fast, and are difficult to resupply.

If you happen to get any PDI ones in stock, I would be more than interested.

[ILLusion]

I had a batch come in a couple weeks ago, but they were all presold before I could even post them up! I tried to order 20 of them, but my supplier only had 8 in stock! Am trying to get more...

[LocoYokoPoco]

Damn, anyway you can put me on the list for one?

[ILLusion]

I can do that.
