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.
