well my breech O- ring " tool " is my cleaning rod ( 3 mm carbon fiber ) with a little tape on the end to make it 4.4 mm. Not able to visit faceting, as much out of the question as me visiting the Danish capitol, a place 10 Leopard 2 tanks could not drag me to.
Yes hopefully😅. My first reg on the m3 is leaking on the atmospheric side hole. Loosing around 10bars per night. I already tried to untighten the reg to fix the problem. Unfortunately, it's stuck like hell. Need to clamp it into a vice. 😢
