Ok, so. Last night I took apart my 110 to work on the mag box, spring and follower. Having a feed issue. While I had it apart I decided to break down the trigger group and clean it. The only issue I had was getting the sear spring and bushing back in. After about 45 mins and several looks at a schematic I was able to reinstall and get it back together. Everything looked perfect.

Well I loaded the mag and cycled it and repeated several times. Feed was working. I gave it one more try. Loaded the mag. Cycled once and boom. 7mm round goes off. Safety was in bolt unlock position.

What did I do wrong? Any suggestions?

Upon breaking down this morning, trigger group is intact and exactly how I left it but it is loose to the touch. I didn't notice it before so I'm not sure if it correct.
