I've never seen a true Mac style lower (magazine in the grip and behind the trigger) that didn't use a traditional Mac trigger assembly. So based on that logic: No. However In addition to the other guy's suggestions I've seen a super safety compatible MacDaddy frame that requires you to cut a small amount of your uppers bottom side just behind the trunnion. It's a lot easier than it may sound tbh it was harder to order the accompanied trip plate from SCS that must be bent. My dumb ass selected the wrong thickness and ended up with a bar instead of a plate. 😞
