I can't use it but I saw sgammo.com has some 5.56 tracers in stock. $86 for 120 round bandoler and $600 for a case of 840. I think they come on strips as well. Just thought I'd pass on the info.
I bought a thousand de-milled tracer bullets in .308 a few years ago on a whim. They were pulled from military stuff, and I've reloaded a hundred or so. Shoot them on occasion when its damp outside.
Same stuff that ctd has in december for $199, I wouldn't do it at that price, but did at the 199. lifetime supply of tracer, but sure better than no ammo. Shooting when damp is a good plan. kids love them, Heck I love them.
