--Smart Parts Ion--
-Redz Body Kit
-SP Q-Lock Feedneck
-SP On/Off ASA
-Shocktech Micro Rail
-Empire Reloader B
I got this Smart Parts on/off because I used something similar to the Smart Parts screw in on/off. I wanted something that would be mounted to my gun. I didn't like my Shocktech On/Off because it was nearly impossible to turn. So I got this for $24.00 and I didn't think it would mount to my Shocktech Drop, but it did. It mounts to any dovetail rails. This on/off works great. Its very easy to turn, looks cool, stops airflow when you want it too, and its cheap. Its very easy, you just turn the knob 1/4 ways & BAM, your done. It also comes with an extra c-clip for the on/off. Stops airflow and then unscrew your tank and then turn it back to open to let it all out. Saves o-rings, and I never blew one yet.
Overall, This product is great. I've been looking sooo long for an item like this and I've finally found it. Get it!

This came stock with the nerve I had and wound up ruining a tank reg. Metal is soft and wears unevenly and offers almost no resistance when it got so much slop that it crossthreaded. And I mean no resistance, business as usual until I went to take it off. Tank goes on..wont come off without a wrench and the first three threads at the pinvalve were fubar. Thanks Smart Parts! I hoped it was an anomoly, that does happen. I received a dark timmy through trade that had the same asa on it, and it did not dissapoint. Immediately started flaking the threads in the asa and pretty much saw the writing on the wall. Put a check it mount on it, sound as a pound.
Im not sure if smart parts got a bad run on the aluminum or what, but the ones I have come across are junk. Its a good design that has been in my experience made of poor quality materials. I like smart parts but after having to buy an asa and a tank reg to repair what this thing did to me I give it an F.

Weird threading, place of nob is not consistent with one another (read review)
I was looking around for on/off to go with both my dm4 and ion. First factor was the macroline setting. I didn't want anything that comes off towards the side because I wanted to reduce the width of my marker... yes.. i am anal like that, but macrolines coming off the sides bothers me. Therefore, I only had but a few choices.
I immediately picked up the smart parts on/off mainly because it looks good, macroline fitting is towards the front so all I needed was a straight elbow. It just requires me to turn a nob to gas up the gun, and degas the gun. Also, I got it along with the S-rail and makes it look sexy hot. Anyhow... those are the reasons why I purchased the item. Do know that I purchased 2 of these. Now for the product itself.
1. When I first took the on/off out of the box, one thing puzzle me. Both the on/off nobs aren't on the same side between the one on my ion and the other on my dm4. one is on the left, and one is on the right. I assume that because they have it that way, I can switch it myself w/o any problems. Even better for me.
2. The on/off came greased up already. Thanks SP for doing that part for me.
3. When I aired up both my markers, no problems at all, no leaks and turning the nob was a lot easier than when I was using my CP and check-it. Esp when you have a lot of air in the tank and your gloves are all greasy... turning the other nobs are a bit more difficult. I didn't have a problem at all with the smart parts on/off.
4. This item looks great. It is glossed back with no designer defaults at all. It fits 100% perfectly with the S-rail and like i've said before... gives it hell of a nice look to it. It also moves your tank forward about 1cm if that really matters.
5. I purchased this item brand new for $20.00
6. I would have to complain about this... on one of the on/off... when I was screwing on a tank, it gave it a sqeeky noise... Maybe because I've messed around with the tank threading of the on/off too many times. I am going to put some oil on it and hopefully that solves the problem.
I think this is a great item. The price is fair and the item looks great. it gave me the option I wanted, which was straight macroline feed, and it is very easy to use. I have no problem degassing my tanks at all.
I would recommend this item if you want something simple, cost effective, compact, and looks great. For the price, you really can't go wrong. I won't give this a 10/10 because it is not the best. however, I am very satisfied with this item over all the others I have used.
You can turn off the air to the gun but it does not bleed off the air still in the adapter. The tank is still supplying pressure to the adapter because the tank it's self was never actually turned off. It will still put pressure on the o-ring as you take the tank off(which is usually the reason for o-rings blowing), which defeats the purpose of having an on/off adapter in the first place. It's alright if you're using N2/HPA and you do not need to take the tank off your gun.
Make sure if you get an on/off ASA, it is one that we bleed when you turn it off, like a CP ASA.

All are equally good. I would reccomend any of the 3.
Trilogy Competition, SLIK Lite Cocking Block(bolt, pin, rod, block), KAPP delrin ball detent, grey Empire skull grips, Smart Parts on/off ASA, CP black rail, Macdev macroline kit, X-boarded Revvy, Nitroduck 47/3k steel, black Redz 47ci tank cover
Knob only moves 1/4th a turn
Can't be knocked into off position
It's an SP product
I got a Hybrid Grind on/off for 24 dollars with rail one day. It leaked after a little use, so the guy I bought it from traded me that for this so he could fix it, and maybe sell that Hybrid off(the color of this one matched my marker, unlike the Hybrid, so I got the long end of the stick). Comparatively, the Hybrid, Function, and this product are all easy to use, take as much effort to switch between on and off, and are all something to brag about having. I would equally reccomend any of those.
Initial use showed that it does it's job very well. There is no one hole in the ASA for the air to bleed into, there are four equally distributed around the pin. This isn't a selling point, but at least we know there will be air getting into the marker, and oil gets in without a problem. In the longer run, it's still holding up fine and is the one Smart Parts anything I have liked.
The niftiest feature of this ASA is that the knob only turns a quarter turn. You can't go past it, so turning air on and off is quick. Twisting it to the left turns the air off, and vice versa. It's no longer than a CP rail(the length of the trigger frame), so extended or shortened setups do not occur unless you mount it as so.
The fitting comes out of the front, and I have found this pleasing as well. It provides for the most low-profile setup your hose can have. Macroline would be perfect, since it can be cut to length.
The knob is on the side, and in turn doesn't move a pin inside the ASA that turns the air on and off. I haven't broken into it, and don't plan to, so all I can tell you is that it cuts the air off while the tank's valve is still opened.
I haven't found any weaknesses. It does what it should, didn't leak(even when used), the four holes around the pin makes sure your oil gets inside and gets friendly with metal parts, and is a real bargain. The only way it could get better was if it came with a rail mated or separate.
Red Smart Parts Ion
All American with 14" Freak Front
SP Bottom Line On/Off
Redz Marker Cover
Mounts On a Rail
Doesn't Supress Pin Vavle (Explained in Review)
I was looking at some on and off's for my Ion to replace my junk Duckbill asa. After looking at the price tags on the Eclipse purge's and Unimounts, when I seen this, I knew that;'s what I would be getting. Also my brother has one on his Ion, so that kind of helped too. He had his on a CP Flame Drop, which was very hard to install in onto. I ordered this, and an S-Rail at the same time, so I would have something to mount it to. I guess you could call this a downside, but not a weakenss really, to this product. It can only be mounted to a rail. I really like this product though. It goes really well with my S-Rail.
Okay, As I said, this On/Off doesn't supress the Pin Valve, so you cannot unspress, if you will, the pin vlave, venting the pressure off the tank. You can only vent the pressure off the marker itself. However, it does what I want it to. I can now store my HPA tank on my Ion, with no constant pressure on the internals.
Overall, another great product spewed out by the all mighty Smart Parts. (Thats going to upset some anti-SP people lol) If your looking for a cheap on/off ASA to be mounted to a rail, then pick one of these up. Looks really nice too.
black to silver fade nemesis, evil bolt, evil ram, evil detonator, evil grips, critical trigger with magnets, 25 gram microswitch from air soldier products, egg with z board, and 68/4500 pure energy tank
Ease of use
Hard to put tank in/out
I really like the idea of this on/off, but the only thing i can really complain about is how hard it is to get ur tank in all the way and how hard it is to take off, it almost seems like the valve pins are too long or something like that, other than that it works great, so if you just man up and get some muscles you will love this part, great upgrade :)
I like this style on/off then all the regular ones, if you don't like the regular ones with the knobs in front of the on/off then give this one a try its very nice.
Ion black. q-lock sp qev crossfire 47 / 3000 halo hopper
freak barrel on order
bop body on order
It looks very smart
Not a real on off
Got this when i saw how nice they look on my mates Ion. It has a low profile and looks very smart.
Knob turns easily. Fits the marker perfect
The bad. Noticed that the bottle eats the threads. Then i realised why. It turns the air of going into the marker. But there is still air pressure in the asa. This makes the tank turn very hard that then breaks the threads. If u leave ur bottle on the marker all the time or if u only remove the bottle when its emty it will not harm the treads.
It seems to only happen when the tank is full and you try to remove the tank.
I do not think its a true on of. The asa with the pin that push in to turn the bottle on or off is a better option. But the sp on are a very smart looking one.
Its your choice to go for looks or a work horse

Easy to use
Wastes as much air as any other on/off
I bought it for 20 bucks new, so that's already a plus; not to mention it was replacing an ugly, heavy, brick-looking on/off I had on my cocker. It's super light and looks nice and barely lets air out when you take the tank off. What else is there to say? I like it.
Like anything, its about what you think looks nice. If you like this product, don't hesitate. Its and awesome piece.
