You would also not be able to use the larger rivnut as the small gun is limited. The small stuff i drill and tap if need be. I like having the more variety of sizes/use. But for the most part im able to get where it needs
Not sure how i feel about that personally but everyone different lol. For my use im happy with my choice. I have yet to use a rivnut on my 40 build though. The chassis and aluminum thickness is plenty to drill and tap.
