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.

For all you people who are too cheap to buy an expensive N2 THIS IS FOR YOU. I have PMI N2 and it doesn't cone with on off but now that is not a problem. it works flawlessly.
This is definitely a great investment. If you dont get it you are missing out!
If you are still reading this blow-up your computer and buy it now!
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.

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!

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.
