T1645G 1.6x4.5mm Vials
Suitable for firearm sighting
Pictures show a replacement for an American friend (it is forbidden to possess any firearm personally here in Taiwan, do not attempt to send anything to us without asking in advance.) Original expired sight inserts were with metal tubes, so new ESI (economic sight inserts) were slightly thicker than the holes. We used T1645G only without shrink tube surrounding. However, it works perfectly.
Free white shrink tube only for those who purchase this vial (please add your request on your order note). Use a hair dryer to shrink it, but you MUST do your best to keep shrink tube and vial together. A pair of tweezers can do the job. Or you'd blow it to nowhere to be found.
