This ammunition intentionally does not cycle the action, for the ultimate in quiet shooting.  Each round must be manually ejected.

16” barrel rifles will function differently with subsonic and super sonic ammo. This ammunition is not intended for semi auto or full auto rifles. If you are unsure how your rifle will perform please check with the firearm manufacture.

This specialty ammunition is perfect for younger and smaller framed shooters who are learning to shoot their family’s full size hunting rifles, seniors who have become recoil sensitive due to age, persons who only have access to indoor shooting ranges that do not allow high powered rifles because of the noise they generate that echoes off of the walls or fear that the bullet will generate so much power that it will pass through or tear up the backstop. It can be fired on smaller plots of land that are safe for firing handguns but where a miss with a rifle bullet would likely travel beyond the property, or the use of a full powered rifle load would disturb nearby neighbors.

It is a perfect round for ranchers to dispatch varmints and predators such as coyotes or bobcats that prey on young calves and small livestock, with a reduced chance of scaring larger animals into a stampede. Subsonic .223 is also the rifle cartridge of choice for military and law enforcement tactical professionals as well as civilians in over 35 states to use with suppressed firearms because the bullet does not reach or exceed the speed of sound and does not create a loud sonic boom as it travels.

This relatively innocuous cartridge, with its low recoil and report will serve many shooters, new or experienced, young and old with an alternative target and varmint round to the loud supersonic standard .223 cartridges and at a price you can afford.

    Great ammo for my Unitah bolt action upper

    Hello, I just wanted to give my opinion of the subsonic .223 I ordered back in July. I was on a military deployment in the Middle East but home now and finally got to try it out. First the Ammo is overall perfect, through my suppressor it’s quieter than my .22. My only complaint and reason why I have not ordered more is that the load does not have enough power to cycle through my AR. I have the rack the charging handle after each shot which get a little annoying. I wanted to share my experience to help in your product quality.

    Very quiet, and nice ammo particularly if you want to shoot suppressed. Velocity seems consistent

    I really love this product. The product is extremely quiet and I felt no recoil!

    Works great, super quiet

    Awesome quality – hushes my unsupressed rifles to .22LR levels, and from a can it truly is “hollywood quiet”. Keep up the good work, Detroit Ammo!
