I thought that the word "tactical" means they hype it, and charge way more for it.
Only kidding.
One could do it with, a manual, the components, a two die FL sizing set a dial caliper, (or something to cull out brass that is too long.) Case lube, a hand press, and a way to remove the case lube once the round is loaded. That is the bear minimum for an AR. (Fast in no way, though it would fit in a shoe box, or tactininja bag
, oh wait I mean "Bug Out Bag"
)
For a step up add a case trimmer, chamfer/deburr tool, a primer pocket crimp remover, and a tumbler. Also add a bech mounted press of choice.
