Newbie Q? PCP Air tanks

[cookselk]

I have been interested in PCP air rifles for some time now but have been reluctant because of the initial outlay of cash for the associated equipment, specifically the air pump or tank.  Recently while shopping around on ebay an idea occurred. 

Can SCBA 4500 PSI carbon fiber tanks be adapted to PCP use?

I see these available in 30, 45, and 60 minute ratings, used they are priced from $50 to $130.  Capacity is indicated as 45 CF for a 30 minute supply, this would seem a much cheaper alternative to the new tanks from some of the suppliers.  Granted these are used but as an example the 60 minute tank that I located was last tested in 2012 and according to the manufacturer's specification had a 15 year life or until 2018.

If this is a viable alternative for air supply, what other fittings/ hoses will I need?

The PCP rifles that I am considering are the Benjamin Marauder (most likely), Evanix Rainstorm, or the Hatsan 65 in 25 caliber.

Thank you in advance.

Ain't that the truth!

I just had 4 scuba tanks done.  My local dive shop wanted $55 each!

I found a small hydro shop. When I dropped them off he quoted me $12 ea., but only charged me $10 each.


Edit to add:  Forgot to mention, the $55 charge included a fill, the $10 did not.  I had to pay $8 a fill to the dive shop.  Still a $37 savings per tank, $148 total savings.

Guess I have some money for a scope now...
