Rick thanks I got your e-mail. Good info buddy! The gun stayed stock only 2 days hey? You 're nuts

Maybe that's some kind of record for the Guiness book of airgun records?
JM's reply is below. It did not answer my question to him which basically was: "Is the arctic kit a full-power spring that I 've been looking for my 350?" I would like to say that JM says in a couple of places on his web site, that he cannot sell guides if you have bought the spring seperately already, but he contradicts that here and says the Arctic spring will fit fine in the factory guides. He says on the web site every spring is matched to the guides when they are made, so he cannot sell guides and hoping it would fit your spring like a glove.
Having read that, I would really rather get an "Arctic kit" if he makes one that includes custom guides (and seal), rather than using the 350's guides. That's my plan anyway.
In any case here 's what he wrote which doesn't tell me a hek of a lot and didn't really answer my questions except the one I asked: "what does Arctic mean and how is it different than others" His reply covers that but not much else about the power the spring provides, and if he has any available for my 350, or do I need to custom order one, etc. He didn't bother answering those. Maybe this was a "canned reply" that he has in a text or Word file that he sends to everyone?
""Dear Sir,
As Todays Specials indicate the items are listed when
made. When it sells out it automatically delisted.
When I list the parts I list the info from the TX kit
to explain the spring. Here it is as it relates to a
TX-others as well except dimensions,
5. New Arctic SG Mainspring. This spring was designed
for the new TX200's with the .558-.560 OD guides (
latest model) The spring is .560 ID x 30 coils x 128
wire.
It is wound in house from the finest wire and goes
through 7 days of processing thereafter. Each is
pre-set and ready to install on your guns guides. Kit
buyers will have the option to buy spare springs in
the future- consumer quantity only""
