Trigger fires with safety on - Elftmann Tactical ELF AR-10/.308 Trigger

Alright I personally cannot recommend this trigger. Installed it still fires the trigger with the safety on. I have a couple opinions on this and I dontthink its necessarily the trigger. I tried this in a 80% lower milled with a router. While its milled beautifully for a router thats the problem its not cnced and as perfect tolerences as a cnc can achieve. Routing allows for slight larger tolerences even with the best kit. So with how precise this trigfer is made and how unprecise an 80 percent lower is it allows to much play and allows the teigger to fire. Installing the bottom plate helped a little and almost made me think It stopped the trigger from firing but putting a good amount of pressure on the trigger on safe it fired still. It probably took a good 15 - 20 lb squeeze to get it to fire but it did and is unsafe for this 80% lowers in my opinion unless cnced by maybe a ghost gunner and even then Ild have my doubts.
