No doubt there are those who would disagree, but there is no perfect home defense weapon platform. Pistols, shotguns, and rifles all have their pros and cons, which can be (and will be) argued forever without resolution.
Even the concept that one of the three can be identified as the “best” compromise platform is a misnomer. The fact is, everyone’s situation is different. Variables like population density, house or apartment, size of the gun owner, financial situation, etc. are all specifics that can impact one’s decision on the “best” firearm.So the discussion of a specific scenario for those who prefer a specific weapon’s systems seems like a more productive topic to cover here. For those of you who swear by your Glock 19 or Mossberg scatte rgun, unfortunately, there will be no exploration of the best 9mm hollow-points or most effective 12 gauge ammo.
The discussion here is solely focused on increasing or optimizing the stopping power of an AR-15 rifle platform being used for home defense, as well as a bit of history.
AR-15 to .300 AAC Blackout
Anyone paying any attention to rifle and ammunition trends for the last couple of years will no doubt be familiar with the .300 AAC Blackout. It was initially developed to fit a relatively small niche. Elements of some special operation groups were looking for a cartridge with better performance than the 5.56 NATO round.
This cartridge also had to be more effective, with more stopping power as a subsonic load than the 9mm in which most submachine guns were chambered. A subsonic variant was a must so it would remain appropriately silent with a suppressor. On top of which, this new cartridge also had to be compatible with the M4 carbine.
Earlier attempts at larger cartridges, chiefly the 6.8 SPC and 6.5 Grendel, for the M4 led to some expensive, time-consuming, and tactically undesirable issues. Primarily, using them required replacing the bolt with one modified for the larger cartridges, and while they fit in the 5.56 NATO M4 magazines, the capacity was reduced.
As a solution, Advanced Armament Corporation (AAC), with the cooperation of Remington Defense, developed the .300 AAC Blackout. Bigger than a 5.56 but smaller than the 7.62x39mm AK-variant cartridge, the .300 AAC Blackout has been described as what the former two would produce if they had a baby.
Most conveniently for non-military personnel, the .300 AAC Blackout is M4-compatible, which makes it AR-15 platform compatible. The Blackout can be loaded into AR magazines, used with the AR bolt and carrier group, generally the entire AR lower. It just requires switching the barrel, and trading out an upper is a lot less hassle than modified magazines and a slew of part-interchangeability issues.
One of the requirements of the .300 AAC Blackout was the necessity for a viable subsonic load to function as an effective tactical round while remaining whisper-quiet through a suppressor. It worked. With subsonic loads and a good suppressor, virtually only the clicking of the mechanism is audible.
That’s not often considered as a great bonus for home defense, but should a scenario arise in which you’re required to use a suppressed .300 AAC Blackout to defend yourself, future you will thank you for the damage not done to your hearing by discharging a rifle in an enclosed space.
So if you love your AR-15 platform but are looking for something with greater stopping power, find a good selection of .300 AAC Blackout for sale and head out to the range.
