I need a new Hop Up!!!

[A\/P]

So what's the best hop up for my CA M15A4 airsoft gun. I don't necessarily need a new one but I want a better performing hop up than the stock CA hop up, which seems to be very sensitive and sometimes will adjust itself while firing. Price really isn't a factor and I would prefer to know the best brand of hop up.

Thanks in advance

I have one and I love it. Stupid easy to install and stays adjusted once you dial it in.

I have found Systema hop up units to be very effective. Get a good bucking too.

This is pretty much your best choice.

I'd avoid the Systema hop up's, they don't really like staying in place and the wheel can turn all the way around on most of them. (Read as, they are overpriced junk.)

My Systema chamber had an axle for one of the dial's break off, so I went back to the stock G&P chamber and was fine.... I'd use a Prometheus NEO chamber over anything though. I had one in my VFC HK416 and it was great.

I'm like the mad bull hop up but when does the LED tracer unit come out? every website says "coming soon."

Madbull released news that the tracer is out, so it should be just a matter of time till your retailer gets them in stock. Priced around $40 MSRP.

Also, for safety reasons, I'd suggest not installing the rubber O ring that stops BBs from falling out of the hop up. You never get to use them, and to make sure your weapon is indeed safe and clear means you need to shoot it upside down 3-4 times (which can be bad for it from what I've heard).

I don't see how it would be bad, but I don't fire upside down often enough to find out.
Ninja, what gun do you use? I heard that some bodies need to be modded for that hop up to fit, and I really want one, but I want to know if I have to mod my body for it or not.

I have a TSD HK416, by the way.

It went in a G&P M16 slabside. No issues at all, just popped right in. I've also seen it has no issues going in a G&G M16.

[Raging Hormann]

Right on. I'll probably end up with one this summer. If I need to do any mods, I am of course ready and willing.

the madbull is the end all for hopups. ive had good luck with systema too.

ASO has the madbull tracer LED units in stock as well.

Systema hop chamber is very good, the dial is not stiff but won't spin freely, it does worth the high price tag.
The Guarder POM hop chamber isn't too bad at all; for $25ish dollars, pre-assembled with the hop packing and nub, I am pretty happy about it.
If you always dial the hop up, get the Systema, more robust.

Fix your signature.

Haven't heard good things about systema. But, one of my friends uses an Element Hop Up and he gets really good compression and accuracy. He uses the KWA bucking that is similar to the firefly bucking.
