u/M18_smoke_violet

I plan on chopping my barrel close to the red line in picture 2 (it’s not the full 1 inch diameter all the way down) and was gonna leave a small space to attach this light mount against the shoulder.

My question for anyone that already has this one, any chance you could measure the width of it for me so I don’t have too much barrel taken off?

Picked up this mk4 not too long ago and haven’t fully decided what I wanna do with it… (currently have a sico sparrow pending approval) any recommendations?
