As long as it is in spec, then yeah there doesn't seem to be a whole lot of difference. Some brands, like Anderson, get a bad rap but it's mostly because their QC isnt as good as some others, which means they have a higher number of lowers going out out-of-spec. I have an Anderson and it's been a great one. I would trust my life to it.

There are 3 certainties in an uncertain world:

1. All Politicians Are Liars
2. All Gun Laws Are an Infringement
3. Taxation Is Theft
