Amazing Rifle

This is an amazing rifle, I have run bad levers for a few years now, but I saw these and was very impressed. There are a lot of companies out there that claim "ambidextrous" controls but few are fully ambidextrous like this one. When I first got this rifle it took a little time to get fast again with my reloads (just building up the new muscle memory), but now I am faster than I have ever been. I also don't have to worry about a bad lever in my trigger guard. THIS RIFLE IS AWESOME!!!

My favorite rifle.

This thing is awesome. I can't find a single bad thing to say about it. Super crisp trigger, comfortable ergonomics, and built like a tank. ADM has out done themselves for a great price.
