Find a .22 kit and keep shooting it. My 5.56 stash remains squirreled away for when I feel like it while I enjoy regular range time with .22.
Remember: .22 will get you thru times of no 5.56 better than 5.56 will get you thru times of no guns.
Not only that, but my Colt-marked select-fire Tokyo-Marui airsoft M4 gives hours of fun when the weather is too crappy to go to the range.
In a victim nation, a classroom full of dead children is morally superior to a teacher holding a smoking gun knowing she just protected her students.
