Using Nitrogen in a PCP air rifle.

Thanks cmatera... I just did some rough estimating using this caculator and I see that if I were to fill my FX Crown directly from the Nitrogen Cylinder I should get better than 100 fills That is filling my rifle to 3600 PSI and refilling it when it gets down to 2000 PSI. I am not sure just how low I can shoot this rifle to before I have to top it off. Guess this is something I should pay more attention to.
 
I am shooting an FX Crown and also an Air Arms S510. I got a price today on a bottle of gas that is completely filled to 6000 PSI and is 480 CU.FT. All for 900 bucks, and the regulator from the Nitrogen to my 4500 PSI tank is another 200 bucks. So for 1100 dollars I should be all set. Don't have to worry about a compressor. Now I will have to do the math, just to see approx. how many shots it will last me. I am thinking I get around 3 to 4 fillings from my tank I have now into my FX Crown. I think I use to get at least 10 fills to my Air Arms.

At $900, are they selling you the Nitrogen tank? How much are they charging you per fill?
 
At those prices, and at $250 per fill, I do not think of it as a good deal. At those prices, I would go ahead and get a nice compressor. I already consider mine at $150 a year borderline worth it. The quality of the nitrogen is not what makes it possibly worth it for me. For me, it is convenience and not having to put 10-20 years worth of air down at once like it would take to buy a compressor, but that is at my lower prices. I think at the rate you have to pay up front and yearly, that would go a different route for sure.

I agree. With the prices I quoted early, it is:

Rental $15-20

My first fill $96

Refills are $42

Drop off fee $40$

$500 regulated hose assembly CGA677. You can see why it adds up fast.

At your prices I would definitely pass.
 
This has been a topic I’ve had questions to ask someone about and I think they have pretty much been answered. And the answer is pretty much that once everything you need to shoot pcp airguns is bought from scope(s)/optics be it day/night vision /thermal, 4500psi bottle, a 3L bottle, suppressor and adapter, bipod or tripod or walking stick aiming post, accessories such as rails/rail mounts,magazines, flip up lens cap, regulators, hoses connectors, perhaps. Chronograph, range finder, IR lights in 940nm and 850nm, reactive targets, at least one compressor and the one or two air line moisture trap(s), enough, pellets to make it worth going to shoot now and again and the airgun itself. Around then the costs go down a bit. Whew!

Baja. You can get a Benjamin Fortitude for $289 at AoA and a $5 tin of Crosman pellets and a $33 handpump from Walmart with a 2 year warranty and be shooting cheap. The gun also has a 5 year warranty. Done.
 
I just got the quote from Airgas here in Marshalltown Ia. it is $62 a year tank rentall and $149.95 a fill, tank weighs 225#. A fill valve setup is $185 or a regulated $489. Currently I am paying $15 for a fill at the scuba shop 40 minutes away and I have to leave the tank for an hour so they can filll it then let it cool and top it off. The trip for the fill is not a problem because we have a son that lives close so we go often.
