To me something just doesn't look right about it. I think it's the grip being to straight up and down. Like it should be kicked back more. I don't know just my thought. I just think the S&W looks better.
i emailed umarex and asked if the new HK416 rimfire would use stock AR parts or the proprietary junk in the Colt rimfire and as expected, it'll be a crappy Colt with HK badging and a nonfunctional bolt release.
if smith can figure out the magazine issue (if that's what causing a lot of these problems) they have by far the best .22lr AR platform around.
