Hi, I recently bought a savage 111 in 30-06 with removable box magazine. Synthetic stock non acutrigger. I took stock of and put in trigger. When I took it a apart a small metal collared washer fell out of one of the action screws I'm not sure where it goes it came from one of the 2 action screws not sure if it goes. I really want to shoot this thing but I want to lock tite screws down and don't want to do this twice thx for any replies!! I did look in savage booklet I got with gun but it wasn't in it. Ps this is a 3 screw stock. Thx guys !
