M24 Sniper Rifle

My latest Sniper design. Hope you like it. constructive criticism please. It was built for extreme accuracy over 25 m or so, and medium accuracy for anything between 25 and 50 m. The scope is specialized, and I am looking to make one which csan be ajusted for distance like a real sniper. The barrel is long, which is why it is so accurate, as the bullet stays straight all the way down. Im trying to get rid of a pigeon infestaqtion im my garden with it at the mo, but had to abandon the quest after shooting my sister (accidentaly of course).
