If anyone is looking for some larger tanks to fill/refill their air guns, shoot me a message. I have a bunch of SCBA tanks that I no longer need and will let go pretty cheap to move them out of the garage. All of them are steel tanks, not the composite ones that have a specific service life. I'm in Wichita Falls, but go to the DFW area all the time, and will even be traveling to San Antonio next month and can bring them with me.
