Yeah that 30-day range pass seals the deal for me. I know people get better deals, like the G23 Gen 4 for under $500 even without a LE discount but it was worth an extra $35 or so for the range pass. And at first I thought it was just for the gun you bought there but you can bring any guns (as long as they allow that caliber). It's only a 25 yard range but still a deal.
Unfortunately Impact Guns is only in Utah and Idaho I think, but maybe someone else close by might do something like this?
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
