So i wanted a rifle and ended up a friend of mine was selling his so i checked it out and thought it was decent. I was told it shoots great but he didn't know what brand it was so i gave him $100 and called it good. Then about a week ago i went shooting and the thing wouldn't cycle right because the safety had to be turned on to pull the bolt back all the way and then off to fire it so we stopped shooting it incase something else was wrong. So we went home after shooting and i started taking stuff apart. I wanted to check out the scope because the few times i did fire it i couldn't adjust the crosshairs. So i took off the mount and scope and handed the rifle to my dad. He then said "Oh Shit, Damon this is a Remington!" I then started looking at it and realized it was an 03a3. I then did some research and found out what i was turning on and off was the magazine itself because in wwII, you would throw 1 round at a time until you needed to shoot them faster and that the safety was on the bolt. So i thought it was a cool story and the fact i only paid $100 for a magnificent rifle! Anyways i was wondering where i can get a rear sight for the rifle. When i bought it the scope and mount were on it and i didn't get a rear sight so any help would be great. Thanks!
