    (verified owner):

    Love this thing. Have had some time to shoot with it and it barely has any recoil. I was surprised by how light it recoils. I had to replace the buffer spring with a lighter spring. Just a pleasure to shoot. And the adjustable gas block is great for running a suppressor. I am a lefty so I do notice a little splatter coming out of the ejection port with a suppressor, but not bad. She’s easy to clean and runs great.
