More info on 6000psi Nitrogen setup?

You might try the search function. Its been a while since I used it but it works well.

I was actually gonna buy me a 6k psi cylinder from a local shop and they would keep it filled for 110$ a fill but by the time I purchased the cylinder (1200$)and a good regulator (500$) I couldn't justify it but that was buying the stuff not renting.

I get mine from local welding and supply dealer Moore Oxygen , I pay $38 for a tank and $7 month rent for tank , this setup will last a long time , hope it helps

I did a google search to find out where to rent a tank in my area. Prices vary. Then I bought a non-regulated valve from Joe B. for $189 as I fill up my 97 cu ft tank with it and don't need the regulated valve (closer to $500).

FYI, the threads on the valve from Joe and on the Nitrogen tank are reverse. Took me about 20 minutes to figure that out!! Once the tank gets down close to what the max pressure is on my gun, I just fill it straight from the Nitrogen tank as there is no risk of overfilling. DO NOT TRY FILLING YOUR RIFLE STRAIGHT FROM A FULLY PRESSURIZED 6000 PSI TANK WITHOUT A REGULATED VALVE. 

I go through about 2 tanks per year. Good Luck!

I do it all the time without a regulator. It is not difficult BUT it does require your entire attention and caution. The valve is easy to just crack open for a slow fill to a gun!

Remember with a regulator you are all set to tether your rifle for an extended shooting session.

This discussion has been on-going on the Guild: http://airgunguild.com/airgun-tanks-compressors-and-filling/nitrogen/ Bob Sterne posted some pertinent information about the number of refills which might be of interest to potential nitrogen users later on in the thread. Also of interest is the blog discussion about nitrogen over on the Pyramyd Air site. 

Part of the discussion is about the "dryness" of nitrogen vs. compressed air. I don't think that argument is valid, as there are a number of ways to dry air before and after compression.

pretty sure i seen it written somewheres where Martin does not reccomend using nitrogen in the R A W air rifles gonna see if i can find i will post if im sucsesful

I would need a good explanation WHY since air is mostly Nitrogen! I operate AirForce, Benjamin, Brocock, Daystate, FX, Kalibr Gun, ShinSung all on N2 with no issues for over a year on most of them. N2 is a guaranteed DRY pure gas.

IMO nitrogen would be ideal for PCP applications since it is dry air which does not contribute to oxidation (within the air cylinder)

Nitrogen is a "slow" inactive gas labeled as an inert gas due to its nonreactive nature with many materials. Oxygen on the other hand is a "fast" active gas that reacts with many materials called "oxidation." Additionally nitrogen is a dry gas that doesn't support moisture while oxygen combined with hydrogen makes water (H2O)

Compressed air is a combination of roughly 78% nitrogen (N2), 21% oxygen (O2) and 1% miscellaneous gases.

If I had to guess, the only negative effect of strictly using nitrogen is the possibility of the seals drying out.

I would highly recommend getting a regulator for the 6000psi tank for safety reasons just in case of main valve failure of have an epileptic seizure or heart attack or stroke or faint or black out or other distraction 
or integrate a burst disk onto the carbon fibre tank if it doesn't already have one as well as onto your air rifles being filled directly from the 6000psi tank to minimize the possibility of BOOOM!!!!.

Just a question here. If N2 doesn't retain or absorb moisture, then how will the seals dry out? I mean if it's hydrophobic and inert, then you shouldn't have to worry about seals drying out correct? Also how do silicone based lubricants "dry" out to begin with if sealed in place if an inert gas is passing over them? I'm ready for my chemistry lesson.

Just taking a wild guess if this is true.

No N2 does NOT dry out seals. There is no hazard at all with N2! I worked with N2 for 25 years.

I looked into using N2 a few months ago. It was $400 lease on the tank for 5 years and I think $89 a fill and they came out and did that with a fill or exchange. This is a large gas supply company that also comes out and fills my propane tank. https://holstongases.com/

Great topic, sounds like an excellent fill option!
Terry, can you please share your findings... tank and the Joe B valve cost? 
Thanks!

JoeB fill adapter for a 6K bottle cost is about $200 give or take.
