For gun barrel inspection, a borescope needs to have good lighting and very short focus distance (less than 3mm) due to very limited space. Also the diameter of gun barrel scopes have be small (less than 4.5mm) to fit into 17 calibre rifle. Normally, the insertion tube is either totally rigid or semi-rigid, side-viewing mirror or lens is highly desired to exam barral walls in details. 

We have two types of gun barrel borescopes: traditional optical fiber type, and miniature video camera type. For video camera type, our USB scopes have manual focus feature, and can connect to PC, Android phones and iPhone iPad to preview and take pictures and videos. The most popular models are Vividia GB-460 (4mm diameter, 24" long probe), GB-430 (4mm diameter, 12" long) and GB-8556 (8.5mm diameter, 22" long semi-rigid).

Available diameters of gun barrel borescopes are: 2.8mm, 4mm, 8.5mm. Side mirror usually has slight large diameter. Our gun borescopes are used by gunsmiths, firearm manufacturers, armorers, barrel builders, precision rifle shooters, and gun enthusiasts. The scope is also called rifle borescope, gunsmith borescope, firearm borescope, precision shooting borescope, handgun borescope, pistol borescope and rifle barrel borescope.
