Re: Lands vs. magazine length, browning A bolt 270
No you dont have to take it out. Just be careful with your dremel and get the high speed cutters that will fit as good as you can along side the rivet. I most of the time end up taking off part of the sides of the rivets before things are done. One thing also to think of is you will need two cutter. They will eventually fill with the aluminum and quit cutting. With two you can switch and keep them cool to prevent this. All you need is two verticle channels one on each side of the rivets. It is not to tough to get it smooth, and works great.
