A sniper rifle is a special kind of gun used by soldiers who are really good at shooting from very far away. It's like having a really good pair of binoculars that can shoot bullets.
The sniper rifle has a long, skinny barrel that helps the bullet go straighter and further. The sniper also uses a special scope on the top of the gun to see far away and aim really precisely.
Sniper rifles are very powerful and can shoot bullets that are much bigger and stronger than most guns. They are also very heavy and have special stocks that the sniper can use to make the gun more stable when they shoot.
Snipers have special training and use their gun very carefully. They have to be very patient and wait for just the right time to shoot. They also work in teams with other soldiers who help them find targets and communicate with them.
Overall, a sniper rifle is a very special and powerful weapon that takes a lot of skill and training to use correctly.
