Which ShotKam Mount Fits My Rifle? How to Measure Your Barrel
ShotKam isn't just for shotguns. Hunters across Canada mount it on their deer, moose and coyote rifles, from Tikka and Savage to Ruger, Remington and Winchester. Because rifle barrels come in many sizes, the right mount depends on one thing: the diameter of your barrel where the camera will sit.
Step 1: Measure your barrel
Use a digital caliper to measure the outside diameter of your barrel in millimetres, at the spot where the ShotKam will clamp on. That is usually 10–20 cm back from the muzzle. Barrels often taper, so measure at that exact spot rather than near the action.
Step 2: Match it to a mount
| Barrel diameter | Mount |
|---|---|
| 12–15 mm | .410 Mount |
| 14.5–18 mm | 28 Gauge Mount |
| 14–18 mm with a moderator, silencer or muzzle brake | Moderator Mount |
| 18–22 mm | 20 Gauge Mount |
| 21.5–26 mm | 12 Gauge Mount (included with every ShotKam Gen 4) |
If your measurement falls in two ranges, for example 15 mm, either mount will work.
Rifles with a moderator, silencer or muzzle brake
A muzzle device can get in the way of the camera's view. The Moderator Mount holds the ShotKam 35 mm below the barrel, so the device stays out of your footage. It fits barrels from 14 to 18 mm and needs 76 mm of bare barrel to clamp onto.
Rifles with a Picatinny or Weaver rail
If your rifle has an accessory rail, the Rail Mount is often the simplest option. It needs just 50 mm of rail.
After mounting: calibrate
Align the ShotKam's reticle with your riflescope at the same distance your scope is zeroed, for example 100 metres. That way the red dot in your video matches your point of aim. Our guide to calibrating your ShotKam reticle walks you through it.
