goodoboy, here is basic AR setup with everything you need for self defense use and nothing you don't


MagPul Slimline furniture (note the extra length of the handguard), Aimpoint H1, Blue Force Gear adjustable sling and weapon light.

The MagPul Slimline stock accepts M-Lok accessories including QD cup for mounting a sling (cup is on the left side). The extra length gives the shooter more handguard to hang on to and protects the shooter's hand from the hot gas block. Slimline handguards further protect the shooter's hand with heat shielding. They are comfortable, slim, lightweight and rugged.

The Mossie Tactical Midnight Mount locates the 12 o'clock position for easy operation. It holds the light securely and in all the years I've put it to use, it's never come loose.

The Surefire X300 is light, rugged and the switch is ambidextrous, easy to use and simple. Push the switch for momentary and rock the switch up or down to lock it on. It's really bright and the beam gives good coverage.

The sling is padded for comfort and it's easy to adjust. Material is rugged and stitching of good quality. It's a good sling.

I can't think of anything to do to make this AR better for home defense except shortening the barrel and adding a suppressor, but that's another discussion altogether would only detract from this thread.
