Smart Parts Ion, 50/3000 WGP WorrGas, HALO-B, CP Razor drop and CP on/off ASA
Strengths:
Effortless on/off, sexy, has ports on both sides, comes with port plug
Weaknesses:
WHY does no one give you mounting screws???
Review:
Just purchased for $25 to fit onto my CP razor drop. I used to have an older one but sold it a while back and the only thing I didn't care for on it was the fact that I kept unscrewing the on/off knob and not turning off the tank! CP has fixed this and the on/off on this one is absolutely effortless. It would killed them to include freaking set screws, but I guess they figured most people could use their old ones which is usually true, except that they don't include them in their drops and they don't include them in the ASA's. So if you buy the drop and the ASA, you have no way of sticking the two together even thugh you just spent $70.
Anyway, it's one of the best looking ones I've used, I like the fact it has ports on both sides so you can mount your macro either way, and they include a plug for the unused hole. Be sure to use teflon tape on it kiddies!
In short, if it's rail mount type you want, this is one of the best. I really like the exchaust port on it so when you turn it off it relieves any additonal pressure in the line.
Conclusion:
Defianlty reccomend to anyone using rail mount style stuff. One of the best and doesn't dissapoint. Just.....buy...set screws if you're buying it with a CP drop because neither one comes with any. 10/32 threads for reference.
Mounting screws your looking for come in another package with a rail in it. this rail is attached to your marker, and the top side of the asa is slid down the rails.
