Switzerland’s most popular native-English-language guns & shooting channel! Probably. Maybe. I guess. A somewhat off-the-wall and tongue-in-cheek look at firearms, military history and shooting, and a jolly good tilt at the windmills of fuddlore to go with it.

We normally launch “in-series” vids on a Friday (early launch on a Wednesday via Patreon and the FB page https://www.facebook.com/Blokeontherange/ ), out-of-series vids launch precisely… whenever.
