I am lucky enough to have Atomic Tactical's front door is 267 steps from of my office chair. I visit once a week to see what's new and to check out the "bargain bins" (which have disappeared for some reason).
Excellent service, great employees. It is great to have a local place that carries every conceivable AR-15 part, in stock - from individual gas rings to complete rifles. Great cash discounts too.
FFL transfers take minutes - super fast, in & out service, $20.
I have been a customer for years (even at the old building) and I have had 0 bad experiences.
Just my $0.02
Good Luck!
