Has anyone heard an AR fired in .45 cal? I have been told due to the subsonic round that it can be fired without hearing protection. With less muzzle flash and sound , might be a good close quarters house rife?

I shoot a subsonic target practice round in my 1911 about 850 fps trust me you aren't going to shoot it with out ear protection. With a suppressor you could shoot it without ear protection.

I have .40 cal semi-auto carbine and it still makes noise, but it is a good close quarters firearm and it has been reliable.

Mine came with one 10 shot and two 20 shot magazines.

Here is one in .45 ACP:

I'm not a fan of pistol caliber carbines, but use whatever you feel comfortable with. That said, it will still rattle your cage in close quarters.

I have an AR chambered in 7.62 x 39. It might be a bit much inside! I was just curious about other subsonic calibers.

It can be done.. not sure if you can just go buy one that's ready to go.

A better option, if these are still produced, would be a Beretta CX4 in 45 ACP (or any similar pistol caliber).

I don't think that noise and muzzle flash receives enough respect when a weapon might be fired indoors. When I was a Navy Corpsman working in the ER at Balboa Hospital in San Diego in the 60's a woman fired a 357 magnum in the treatment room at her husband. The lighting was dimmed and the muzzle flash blinded me and the noise was deafening. It was absolute chaos with people diving for cover or trying to grab the woman. The noise cleared the whole waiting room and we ended up treating a dozen or more people with injuries even though the bullet itself only hit a cabinet and punched a hole in the wall. This was nothing like the depiction of an indoor shooting as seen on TV or in a movie.

I used to own the Beretta carbine in .45ACP and I can confirm that it is much quieter than probably any gun I ever shot. I even had people comment on how quiet it was when at the range.

That gun has been discontinued. I sold it because it only had 8 rd magazines. I traded it for a 9mm model that accepts 20 and 30 rd magazines.

As for a 45ACP AR rifle, I would consider it a toy and not a serious use home defense gun.

There are some decent 45ACP carbines, but they are expensive. Like the HK USC carbine. Or Kriss Vector. The High points generally work if on a budget.

The bullet may be subsonic the the muzzle gas isn't.

As stated previously, you need a subsonic bullet with a suppressor to get down to hearing safe levels.

Pistol cal carbines have enough compromises that I wouldn't recommend one as a primary bump in the night tool. You'd be much better served by a compact rifle or shotgun.

Lets be honest. A Beretta CX4 9MM carbine with a 30 rd magazine is a fantastic home defense gun. Its better than ANY pistol.

How so? It's a bigger, more cumbersome platform that shoots the same identical cartridge.

I currently have the use of a High Point 45 Carbine. It's pretty loud. I suppose you could fire it outside without ear protection, and your ears won't ring for weeks, only hours. It certainly does not have that ear shattering pressure of a 45 pistol. But in no way is it quiet.


People who count on their fingers should maintain a discreet silence.
