HK releases the RAPID FIRE VALVE

[martix_agent]

I just ordered the HK RF Valve for S&G... we'll see how it turns out. My main concern though is that I REALLY want to be able to fire in semi whenever I need it. If this goes off full auto every time someone just looks at the trigger then no bueno.

I was thinking: imagine someone on a budget that just gets an Emek 100 and such a valve. I guess there would be no need for an aftermarket 3-way and trigger. That's a lot of firepower on the cheap.

This is definitely an issue with the new valve. It sounds like you don't always get 1 shot per pull. Sometimes you get 2-3, even though you wanted 1.

This looks like a company saw he "fin delete" mod and made it a product.
8% is a big number, I'm surprised they're throwing that out there because you know people are going to contest it.

I think the big change isn't necessarily between what we see on higher-end gamma's (the 4 post design) and this, but more on the "honeycomb" style gamma's you see in EMEKs.

So I've heard. I have a DW hAir 45 + ID Fang trigger set-up. When I'll try the HK valve, I'll switch back to the stock valve if need be.

I never noticed the difference, but just pulled out my Emek and see what you mean.

I might actually buy this, now!

The only possible issue I see with this design over the honeycomb is that the emek valve is removed by twisting. I would be afraid that if the bolt or front can bound up it might bend the posts. The other gamma core guns are toolless and pull straight out instead of twisting.

Fair, but it says this is designed for the emek. I wonder if I could buy a spare chamber and cut the webs out a bit.

I have to stop thinking up projects, and start finishing them instead.

oh wow. There is a difference in the emek and other gama cores. My gen 1 GTEK doesn't have the honeycomb design. I wonder why they did that. Cheaper to manufacturer? Maybe it's got to do with it being screwed in, instead of just sliding out?

[flyweightnate]

Certainly looks cheaper - drill instead of mill!

I have a spare on its way and will be... adjusting it for science.

[MrBarraclough]

Probably both. Less milling and more robust.

[flyweightnate]

I modded a spare can and saw a negligible difference in velocity, trimming a group of three holes into one big triangle. Color me suspicious that the improved flow is better than placebo.

My local field has already started making anyone with a mech Gamma Core hold the trigger for a second to show it doesn't have one of these rapid fire mods installed as part of the chrono procedure. I presume we'll see more of that as these things proliferate.

I played at a field New Year's day and the refs grabbed my Emeks off the table and took them out to chrono and test them for rapid firing. The owner mentioned a rapid fire valve and we talked about how we both didn't really like the single shot issues. They were aware and looking for it.

Though I used mine for a game at my home field a few weeks ago and no one said anything. It's easy to switch it out, so if refs aren't watching, you could get hit with one. I used it when we had a bunch of guys ramping and running down the field with electros against a bunch of rentals and mechs. I did slow them down a little that way but that's a different issue. To be fair though, the field owner let my oldest son borrow a rental emek that had the oring cut to shoot full auto. He was shooting faster than I was when he held it down. Mine shoots about 12-13bps on full auto with the HK valve. I bet his was closer to 15.

The Whisper chamber thingy already has a lot of great reviews. I have one now, just installed but won't get to use for another week.

[Cyberpyr8]

I bought one. I don't notice a lot of difference in sound. I also used the nano barrel and it was almost as loud as it was. It might be a little softer shot and I'll see if there's an improvement with efficiency. I'm not instantly impressed with it. When I go to the field I'll do a better test and a buddy has a similar Emek without the whisper I can directly compare to.

[The Jayster]

Well, I got my valve and installed it. With a fully stock Emek, there is no way to reliably fire off a single shot every time I pull the trigger. That's both when dry firing and actually shooting paintballs. Worse still, when I tried to shoot a string of single shots I'd often ged mad drop-off (below 200 fps). I know, I had a chrono. However, when I did fire full on the streams were steady with no discernable drop-off. I was using old paint on a cold day and had no issues whatsoever.

When I tried the valved coupled with an aftermarket Exalt trigger, forget it. The thing became possessed and wouldn't stop firing. I had made sure that there was plenty of play so that the valve rod had ample space to reset properly, but still.

Yet, for now, I've decided to keep the valve along with the stock trigger. At least with the stock trigger it is actually easier to fire off a single shot or two for chrono purposes. The beauty of it is that within 30 seconds I can easily swap valves if I want to. That for me is the clincher. This Emek will make for an awesome loaner or for overall s*** & giggles purposes. OTOH, I can easily revert to the stock valve and slap on a PAL loader, going for a totally different effect (slow ROF - I find that the PAL works fine with a fully stock Emek, but can't keep up even with only an upgraded trigger).

By the way, it so happens the field I was at offers the cut o-ring mod to Emek owners.

I also bought the cheaper Core Ignition Valve and it does the same thing. These valves are only good if you want to do full auto. Though, I didn't have the drop off issues you are seeing. I gave my RapidFire valve to a buddy with an EMF and he didn't like it either. I have my Emek back to Hair45 and fang trigger configuration. It rips that way and is predictable.

It's funny the field offers that option. Most fields don't want people with rental guns shooting that fast. Though I borrowed an Emek for my son from our local field one week when he was in town and they gave us one with the oring cut shooting full auto. But they don't normally let people use it.
