One of the guys from work has a Nitrogen tank that he is willing to give me I'm not sure what company the bottle is with but I know I may have to get a contract to fill it ....

I guess what I realy want to know is ....is nitrogen as good or better than air? Will it last longer ? What will the conectors cost so it can be used to fill my gun?

I'm still real new to the performance airgun world but with the opinions from you guys I'm sure to make a educated choice

Thanks for any advice !
