I have built many things over the last 6+ decades and have an outdoor range. I have attended the NRA Range Operations and Development course ( great ) If I was to build ( the plans I have now are for a 5 lane 7 yard range ) a portable range that I could move to weekend gun shows or gun stores would there be a demand for my services? I can build it to meet all safety ( projectile containment, air quality, and noise containment) requirements but it will not be cheap and I don’t want to do it unless I can reasonably expect a return on my investment. I just want to hear from you the shooting public. Thanks in advance for your thoughts!
