Lights and cameras are a must. I have solar powered blinking red lights alongside my driveway that let anyone entering my property know they have been seen before they get all the way to the house. I have a very similar bag hanging on my bedroom door. I like how you have a TQ accessible on the outside of the bag.

While the wait times are WAY low (nephew just got his approval in 13 days), get a suppressor, especially for the .300 blackout. You don't want to be shooting an AR indoors (ie home defense) inside your home if you value your hearing. Personally, my AR and secondary both have suppressors on them. 8" .300 Blackout (registered SBR) with subsonic loads and an FNX-45 (.45 ACP is naturally subsonic).

Good content overall... but if you toss that airsoft device at the cops, they're not just going to fall back and regroup to find out what's happening. For all intents and purposes from their perspective, you (the "bad guy") have just attacked them with some kind of BOOM!, so their first instinctual reaction is to start shooting as they get to cover. Even in the scenario where they've got the wrong house, THEY don't know that. They're already in a high-stress, high-adrenaline fight mode and they're not going to be thinking slowly or logically, calmly communicate with you, or give you the benefit of the doubt. If you KNOW it's the police, you've got better options... or you're going to get Malinowski'd. If you DON'T KNOW it's the police, (whether it is or isn't) your tactic *might be a good option... or you still might get Malinowski'd. I'm not saying you shouldn't use that tactic, or that you shouldn't defend yourself and your home - if someone kicks in your door and they haven't identified themselves as LE, they get the BOOM! and the business end of that 300BLK. The airsoft device is a great idea in the non-law enforcement scenarios, but a terrible idea if it does happen to be LEOs. Just my opinion. I subbed for more content! Best of luck!
