I had an extra SD3G trigger lying around so I put in my SR15 mod 0. During the last stage of the half and half drill I experienced 2 ftf with light primer hits. The rounds fired fine later. The ammo is American Eagle 55gr 5.56mm.
My diagnosis is that I’m firing too fast for KAC’s finely tuned gas system and the hammer is following the bolt. I have never had a malfunction in this rifle before. So the original KAC trigger is going back in for now.
Am I correct here, or is something else going on?
