Hey guys, I purchased the RA-Tech trigger set for WE AK74, and it installed without any issues. However, my full auto isn't work at all. I figured out what the problem is, and apparently, the steel selector lever isn't pushing down at the back of the steel sear. This is caused by two things that I have noticed:
1. The RA-Tech sear is significantly shorter than the stock sear
2. The RA-Tech selector lever is slightly thinner than the stock selector lever.
Because of these two issues, the selector lever is not engaging the sear at all and cant push it down during full auto. Notice in the picture below, Ive highlighted the difference in length of the back of the sear sticking out. During full auto, the selector lever only pushes down at the back of the sear, but in my case, it cant even push it down because too little is sticking out. As such, full auto doesnt work. I read that people had no problems installing their RA-Tech kits and it seems pretty straight forward. Im just wondering if I got a lemon because my sear is soo much shorter

Here are some pictures to show the problem:
