I like Brownells Mag Tips, but a few points:
#1. There are other brands of tips , made in USA that are same quality.
Brownells doesn’t make them.
#2. The brands that seem to be real popular are mostly junk. Check close
and you will find China in fine print. That’s enough for me but I’ve
never seen a Chinese tool worth carrying home, including a hammer.
#3. Sets, I’m not much on sets regardless of manf or tool. Half the set you
never use. I buy the bits and taps I use in units.
#4. Sets like Grace, Forrester,ect are decent tools but only fit limited
number of screws. They don’t have enough range.
#5. If you are going to be doing most of your tinkering with certain guns
buy the appropriate tools. It will save you in the long run. You can
very easy get into the cost of a screw driver buying one gun screw
with shipping & handling.
