FX 500 Air stripper and cone piece measurements

jking · Jul 17, 2017

Was wondering if some one could share with me the measurements on the air stripper ID and the screw in cone pieces ID on the end of the moderator. I drilled mine out hoping for a accuracy improvement and now I'd like to go back to OEM sizing. I'm assuming the parts are different per caliber.

Sorry, but this is the closest I get to your question from where I am at the moment, but guess you have sorted that out.

It looks like someone would just measure theirs and respond. Mine is drilled out so i cant help. Maybe someone else will chim
in.

Thanks Gunnertrones, I have that information but it doesn't detail the measurements. Scalf, I realize that most of the shrouds are glued on so that makes it almost impossible to do a quick take-apart. AOA as you know said the end cone piece was .252" for a 25cal. I'm not buying that. I was measuring .255-.257 on my 400's ID. Visited with Weatherby aka Mr. FX to me and he had some ideas on repairing mine and then I can re-bore the holes to something that makes sense.

My 500 that was up for sale fell through so, it's back out of the box. This gives me a chance to do some side by side for you before I box it up again.
Definitely a difference!

Caps...
ID
400 = .244"
500 = .295"
All other dimensions are basically the same. eg. a 500 cap will screw into a 400 shroud and a 400 cap will screw into a 500 shroud (ouch!).
Length of tube with rear cone,
400 = 10-3/8"
500 = 15-3/8"

Very nice of you Tom to go the extra mile. By chance did you measure the air stripper bore? This info will really help me to get mine back to factory specs.

Damn, what a great reply Tom. Nice pics and the info Jimmy was looking for.

Jimmy, you weren't kidding when you said you weren't buying AOA measurement, they weren't even close.
