Y’all, asking for a friend:

Let’s say someone would like to put together a stable of Ars, each with its own purpose, i.e. home defense, range toy, truck gun, neighborhood defense, 2/3-gun competition, SHTF meat gathering, big middle finger to the grabbers, etc.

For what purpose(s) would you own your AR(s), and in what format/layout(s)?

Examples:
10½” SBR in .300BO with a can, a cheap red dot/laser/light, and a basic adjustable stock for home defense.
- or –
7” in .223 Wylde with BUIS and a blade for a truck gun.
- or –
20” A1/A2 with irons in 5.56 to harken back to my days with Uncle Sugar.
- etc…

Not looking for brand names (feel free if you want), just basic whats and whys. Details can be worked out as and when needed.
