Thank you, Geissele!! - John

Like the previous reviewer I love my ACR, but hated the stock trigger. It felt like I was grinding sand in gears every time I pulled the trigger. I just replaced it with the Super ACR trigger. What a beautiful difference this trigger makes. Silky smooth first stage and clean second stage break. No gritty feeling. I can't say enough how much an improvement this is. Installation can be a little frustrating, but that is in no way a fault of the trigger. Just be patient. There are a couple of really good videos on YouTube that show you how to do it. It took me about 10-15 minutes to swap it out. Only tools I used were a flat head screw driver and small punch. WATCH THE VIDEOS!!! Anyway, I can not be more pleased with this trigger. I'm now a Geissele customer for life.

Great upgrade for the ACR. - Derek

I really like my ACR but the factory trigger was grittier than a salty Drill Sgt. OEM trigger was heavy and felt like it had sand on the sear. I replaced it with this unit and OMG what a difference. 1st stage is about 2lbs, 2nd stage feels like 1 1/2 with a glass-like break. This feels closer to my SSA-E than it does my SSA. Also, there is almost zero overtravel. You might want to have a friend help you install it though, you'll need 6 hands. Maybe Bill can link a video of the install. It's kind of tricky to get the right leg of the hammer spring into position on the selector lever, when installing the hammer.
