Russian assault rifle Anti air missile Sniper rifle - looks like a Russian draugnut sniper rifle. Combat rifle- the most modern looking weapon. Covert pistol- it has a sound supressor
It is possible, and in the history of silenced weapons it may have been done for some special purpose such as assassination, but the rifle will still make an audible sound. With any rifle, the bullet will hit the target before the sound reaches it anyway, and that time is increased by the extra range of a sniper's rifle, so there is little point in silencing them for most wartime applications. The sound emitted can be reduced further still by using subsonic ammunition, but this is less effective, and also can reduce the effective range.
Do you mean "What sound does a rifle make"? If you do, it makes a very loud "pop" similar to shooting a cap gun but about 1o times louder.
A short-lasting, but loud noise. Such as a rifle shot, or a hammer bang. These make the sound appear louder than it really is.
Bayonet, scope, grenade launcher, sling, muzzle break, sound moderator, etc..
The FIRST sound would be the crack of the bullet making a sonic boom- most travel faster than the spped of sound. The second is the sound of the gun firing- it takes longer for the sound to get to you than the bullet takes to get to you.
Could be several different reasons. Are you using the same weight pellet. Different pellets create a slightly different sound. Also a new rifle has a break-in period, it takes about 100 to 200 shots for an air rifle to break in. The air chamber settles down over time. Or it could be just where you are standing. If you are close to a wall the sound bounces off the wall back to you. Also never dry-fire a pellet rifle this will damage the air cylinder and never leave an air rifle cocked for days on end, it will damage the spring.
