Thread: Can Questions

Use calipers and measure width of barrel where the bush will go. Drill to that size, you're ready to go.
Ask an engineer mate if you can use his drill bits and press so you have the choice of 16.3, 16.4mm etc rather than using the 16.5mm from mitre10 because it's "close enough".

If you want an overbarrel without needing to do a bushing then look at a hushpro.
