I recently swapped a couple 308 AR barrels, which gave me a reason to use the Geissele Gas Block Roll Pin Tool. It made starting the roll pin extremely easy. I wish I'd purchased it years ago (if it was available before now).
Bending 1/16" punches is definitely something I do well, so I'll be getting their punch set at some point.
