These Swabs are made especially for the collection of biological evidence from the inside of a gun barrel.
As opposed to the use of small standard sized swabs, the Gun Barrel Swab collects more biological
trace material from the complete inner surface of a gun barrel due to its form and size.
Just add a few small drops of distilled or DNA-Free water to the foam tip and you can start collecting.
The Gun Barrel Swab comes in 4 different sizes: .22cal/ 5.56mm., .357cal/.38-cal/9mm., .40cal/10mm and a .45cal/ 11.50mm.
The foam tip is connected to a 21.6 cm./8.5 inch long plastic handle.
Each Gun Barrel Swab is hermetically sealed and made DNA-Free by ETO (Ethylene Oxide).
