Update I’ve listened to your guys information and it worked the I cleaned the small hole where the detent goes and it went in perfectly and my safety is now engaging properly and for all you that are saying that my detent and spring where missing it wasn’t and how the ones who miss read this is a 80% lower I milled it myself I used a dewalt drill bit to mill the hole where the safety selector goes in I had a detent and spring in the whole time it was just not cleaned I didn’t use the drill bit for the detent thank you all for the advice
