For sale/trade is a Night Blaster Tracer Compact Varmint Hunting Light Kit made by Optronics. This is model # GL-100C. My bro-in-law found this in his gun closet and asked me to sell it. He never used it, but we did test it to make sure it functioned and it does. I honestly don't know much about this weird little light, but feel free to ask any questions. Asking $20 or will trade for ammo or.....????
