Closed bolt Ion conversion kits - updated version
50 sets in...
Bolts and tail insert are anodized.
Newest design does not require any threaded components, and has integrated chamber devolumizing. The firing piston has also been redesigned with one of the seals being stationary instead of 2 seals on the tail - this allows the supply air to provide a holding force when the piston is retracting to prevent the possibility of the piston bumping forward after retracting, as well as helping it to open faster. Another advantage to the new style is that there is an optional installation that lets you hide the complete assembly inside a stock Ion body with no tubing showing outside. Requires a permanent modification to the firing can to do this, as well as shortening the piece of the kit that fits into the tail of the can and putting a groove into the donut, but allows for a 100% hidden setup. All of these modifications are able to be done with a dremel tool and a 10-32 tap to deepen the threads for the rear air fitting.
Operates at ~190psi, obviously varying quite a bit depending on paint and barrel. Efficiency also varies with paint and barrel - expect 1,600 - 2,000 shots per tank depending on those factors at ~300FPS (I get ~1,800 with the paint I get locally in a bore matched barrel - smallest I have - shooting 295-300FPS - efficiency is exponentially related to velocity - 270 could give you ~2,200).
Price is still $75 shipped and paypal'd. Includes conversion components seen, as well as all fittings needed, new tubing, and a set of replacement seals.
For customers that have purchased a mechanical conversion kit from Deathwish_DW and myself, price is $65 shipped (make sure to let me know before paying via PM). If you want a mechanical conversion for these and do not yet have one, let me know before hand, and I can coordinate with Deathwish so you can pay all at once (he has all of the stock of the mech kits for shipping). Overseas/international shipping is not a problem, PM me for requests.
I have a backlog of requests in my email for these as well, I will be contacting everybody that has requested information on when they were available, but it will take me a few days to wade through the PMs. Feel free to shoot over a fresh one even if you know that you had sent one previously.
OLD TEXT BELOW
I am finally releasing my conversion for a closed bolt Ion as a nearly drop in conversion kit. This valve system is the same operational concept as the one being used in the MCB open source group project. Main purpose of the kit - efficiency. Tests indicate that anywhere from 1,600 - 2,300+ shots per tank is achievable. The low end on that scale is from mechanical conversions without a QEV and a slight overbore, the high end is electro conversions (no QEV) and mech conversions using a QEV and bore matched paint.
As indicated, the system can operate mechanically or electronically. The firing piston seals the dump chamber immediately before firing, nothing required for mechanical operation other than a normally open 3-way valve such as the Clippard SMAV-3 - which is often found in Ion mechanical conversions (readily available from Airsoldier.com).
The only permanent mods needing to be done to the Ion are a hole in the back of the body (less than when doing a BOB mod) and a channel cut into the bottom of the body to allow a hose to reach to the back outside of the frame. A hole can also be drilled into the frame for the hose relocation as well. No metal cutting is required. All other components lock in place with no modifications.
The conversion kit works on original Ions (XE kit is now available) and Epiphanys. The stock board works for electro conversions - but the eyes are not functional. Third party closed bolt boards are required for eyes with the electro conversion. With the stock board, the dwell acts as a ball in place delay as it is not important to the firing sequence and has no impact on efficiency or velocity - just how long the bolt is open. Force feed loaders are recommended.
Price is $75 shipped and paypal'd. Includes conversion components seen below, as well as all fittings needed, new tubing, and a set of replacement seals.
-Current kits do not include the replacement donut and rear plug - these pieces have been replaced with an updated design that does not require as much body removal and stands out less visually. See posts below for pictures of the current pieces. Originals not replaced as reference for those with them.

Would there be more interest in kits for an XE?
Is the kit priced too highly? If people think these belong in a different range, please let me know.
Wow $100 per kit. I think that might be a little high specially if the eyes don't work. I have an ion that I no longer use. I would like to toy around with a closed bolt system but I can't get myself to pay for the kit. Now if the kit was priced around $50. I would consider it.
It's impossible to have a closed bolt system for an Ion that uses eyes without a new board.
I'd never be able to get it down to $50, at least not without having them mass produced in China. I suppose I could split the difference though, I'd rather make less than hoped than nothing at all. I'll update the original post.
If i had an Ion I would pick one of these up, this is wicked cool. I love it.
Keep up the good work =)
i am interestedin the closed bolt kit, but im on the fence with the ion i have right now.
but knowing the work you have done, might you have some parts i could use to put together a mech ion, (the valve and or barbs)
if you might have anybody feel free to lmk me here or on PBn.
thanks, and im really psyched into getting my hands on one of those fasor kits youve developed.
A normally open 3-way mechanical valve is, incredibly surprisingly, not in the list of valves that I have. I've always just plugged up a cocker 4-way when I needed one, which is a less than elegant solution.
Haveblue has SMAV-3 valves on airsolider for a very good price though.
Which FASOR kit, I've done a couple of them :)
I'll make a pictorial installation guide for one tomorrow showing where the fittings go, and the general cuts that need to be made to the body. Good idea.
