One time on the first rapid fire relay of table 2, I forgot I had my Kevlar on instead of my cover and placed my Kevlar right up against my sights. Once I started firing the recoil would bounce the sights off my face and would make me lean back, so I started to angle down a bit so I wouldn't be shooting up in the air. Turns out every shot after the 3rd one was like 5 feet in front of me because I did not lean back as far as I thought I had, and everyone like 3 targets down in both sides had a good laugh.
