This!

seriously what's so wrong with the ruger?

I think the biggest downside is that it's got a proprietary rail system

but otherwise it looks like it's good...

For just below $2k, take a look at the Robarm XCR if you want something very reliable and different.

I like mine as well. Had it about a year with 2k+ rounds through it. The only small issue I had was getting jams from 5.56 NATO or other hotter rounds on the default gas setting. Dial it back to 1 for those, and it's GTG. Proprietary rail kind of sucks, but at least it's unique :P I've had a lot of people ask me what is on mine. You can see it in my signature picture.

if you're gonna drop 2K+ on a piston AR get an LWRCI M6G...they're dope...same stuff MARSOC as well as other SF units use, utterly reliable and proven, you can't go wrong

Interesting. Do you have a source for that?
