Not Thomas but I’ll throw my 2 cents in if that’s alright. I would disagree with the opinion expressed by this friend of a friend, and let me explain why. The noise level of a firearm shouldn’t really be one of the first priorites when looking at a weapon for defense situations, most all firearms produce noise levels that are in the permanent damage range, especially in an enclosed area. This doesn’t mean you shouldn’t consider noise levels at all, but when it comes to the best possible way to defend your home noise isn’t going to be much of a factor, and can actually help in some situations. John Lovell of WPS actually has great video on this where he disucusses actually not using a supressor in a HD situation because of the advantage it gives him. When someone is attempting to come into your home you want to “descend on them like a fire-breathing dragon” to quote John, and that is exactly what an AR-15 does. As loud and frightening as the muzzle blast and noise may seem to you firing the weapon, it’s incredibly more so to anyone on the receiving end, and can be very advantageous if facing more than one assailant. In the moment with all your adrenaline pumping you most likely won’t even notice the noise, but anyone attempting to invade your home who is unprepared for it will all of a sudden be met with a feiry explosion (or multiple) blasting their direction. While yes, it may cause some permanent hearing damage this is going to be the case with most firearms fired inside the house, so you may as well defend yourself with the best tool for the job. An AR-15 is hands down one of, if not the best weapons for home defense. They are far easier to control and aim under pressure than a handgun, and they are far more precise than a shotgun with far less chance of over penetration or collateral damage. Most of your standard 5.56 rounds will barely penetrate through a standard sheetrock wall, and more often than not dispel all of their energy into the sheetrock and come out the other side in non lethal fragments. Lead 00 buckshot on the other hand will punch right through a wall and keep on going, and even 9mm or .45 ACP are capable of penetrating through several walls before stopping. So I wouldn’t let noise hold you back from buying an AR, the advantages they offer far outweigh the increased noise levels, and a little bit of hearing damage is a LOT better than losing a gunfight. As for suppressors, most suppressors designed for AR-15 platforms are around $500-$1,000 plus a $200 unconstitutional tax stamp, which is what any decent AR is going to cost you, so no, they’re not double. Also keep in mind that a suppressor does not make the weapon magically quiet like in the movies, a suppressed 5.56 area is still within damaging noise levels. The main advantage a suppressor offers is flash suppression, which like I discussed above may or may not be to your advantage depending on the situation. The one area where a suppressor on an AR can really shine is on a 300 BLK build. Subsonic 300BLK rounds fired through a decent suppressor are hearing safe, and can be a great option for a HD build, but again are not without tradeoffs. 300BLK rounds will penetrate further than a 5.56 round, as it is a much slower, heavier round and will not break apart in sheetrock, and 300BLK is a fair bit more expensive than 5.56, so buying ammo to train with will cost you more as well. We could have an entirely different thread on the advantages of 5.56 vs 300BLK but just something to consider when looking to purchase your first AR. Remember to have a clear purpose in mind for the rifle, and let that purpose dictate what kind of rifle you decide to go with. Is it purely for HD? A SHTF rifle? Would you possibly want to hunt with it? All things to consider when purchasing an AR. As always we’re glad to help in any way we can, I’m sure Thomas will have a reply soon (hopefully agreeing with me lol) Also here’s the video from WPS if you’re interested.
