Alias Intimidator or empire sniper valve pin for spyder valve

[devilzcall]

I'm still on the hunt for a non-blowback 11/16th valve for my SPump, but I'm not keen on importing one. Autococker parts are also somewhat hard to find, but I stumbled upon two clearance listings from a local-ish store.

Since I really only need an uncut valve pin, I'm wondering if one of these might be compatible enough with my generic 11/16th spyder (nelson?) style valve:

Alias Intimidator Pin and cupseal

Empire Sniper Cupseal (and pin, i hope)

The Intimidator pin looks perfect for lower pressure Since I already have a regulator on the gun that isn't doing a lot right now.
I am much more positive that the sniper pin should fit though. Can anyone weigh in on this?

Alias poppits people actually want in the states....

I don't think it would work for a spyder valve though.

The empire valve might though. They use similar specs to the Spyder clone rebel

I could probably send a bunch over for fairly cheap. Flat pack international shipping to the states is only ~14€ tracked, but many shops only offer 30€ package sizes.

I also had a stroke of genius and looked up the o-ring size for that part and it should be an 004, so 5.34mm OD which is slightly larger than my valve pin (5mm), but should fit without the oring, or maybe even with a metric replacement.

I am pretty sure I have a complete empire sniper valve if you want that.
I don't think the pin fits the average spyder valve, though there is a fair amount of variation.

Realize now that you are in Germany and don't want to import. But the Empire sniper valves are generally inexpensive if you can find one in country.

[devilzcall]

That's a generous offer, but I've now sprung for both of the valve pins to tinker with.
I actually can't find a full sniper valve in any german onlinestore...

Gruß gott! For what it's worth, I used a Spyder Magna Port (I think?) valve in an old Trilogy Autococker, along with the stock Trilogy valve pin and it worked fine. So maybe the reverse will work in your situation. I'm sorry I can't give you anything certain, though.

Interestingly enough my trilogy valve pin has a diameter of 4mm while my speedster mg's valve uses a 5mm diameter.

I got both pins in and while I haven't pulled out the speedster valve, I can say the empire pin is slightly shorter than at least the trilogy pin and the intimidator pin is significantly longer (~4mm).

Received the parts, my findings are interesting:

From left to right: Stock (but trashed trying to modify it), Empire Sniper, Alias Intimidator

The sniper pin is slightly shorter but has the exact same diameter as the stock pin (5mm). Good, and in my case cheap option, but probably not suitable for low pressure operation.

The intimidator pin is 5.2mm in diameter and a few mm longer. It was binding in the valve at first, but I was able to fix this with just a bit of polishing paste and a paper wipe. The fit is just perfect and almost airtight without the o-ring (which was too thick and had to go).

After reassembling the gun with the new pin and - without touching the reg or velocity adjuster - my first shot was 340, where it was previously set to 260fps. I had to turn the velocity adjuster all the way down and was still able to drop the pressure from 350 to 270psi until I got back into the safe/playable FPS range.
Of course those numbers are anecdotal and from single measurements, but even if you take it with the biggest grain of salt, I'm pretty impressed by the results.

I attribute these drastic improvements to both the narrower shaft for higher airflow as well as the longer pin that should significantly increase the open time of the valve. It's probably not a good choice if you're going for efficiency.
