Due to special viewer request, PPC Airsoft gives his take on the ACETech Lighter S Tracer Unit. Available for some years now, this airsoft tracer unit is very compact and can be easily mounted on pistols without upsetting the balance when handling it... "Viewer request! Thank you very much. A number of tracers released by ACETECH. It can be said that it is a standard model among them. Result: The BB cost is high, but it shines so much that it is fun even in the daytime."
