Electronic muffs also have the advantage of sound amplification, not heard with normal hearing.
use a Glock 40 with Underwoods at 2300 fps. for nightstand. and Holosun dot, and light, electronic muffs. (Dot has auto on/off)
For serious stuff, a NFA AK-47 with forward Ultimak scout type mount and a tried and tested Tasco 42mm Propoint, which as pointed out amounts to a more visible front sight type setup. If the they are in the "circle" its a hit.
Also keep 4th of July smoke bombs and whistlers handy
Downstairs, 300 AR pistol with 40 rd. mags, 208s loaded to 1200fps, and Blackout powder (no flash, lower pressure) Tru-Glo, laser and light combo mounted top rail, laser can be used and visible thru Dot window, if either battery goes down. (Dot site has 4 reticles, depending on lighting.)
Pool house, Troy AR-15, 1x8 Eagle Vortex. 75 gr. HPBT
And for those that are trying to run away, a Sako TRG 22, 308, and Vortex Razor located for easy access on the roof.
