I've got a Sig M400 chambered in .223/5.56 Nato with a 1x6 sun optics scope, bipod, and Binary trigger. The Binary trigger is awesome! Don't use it as much as i planned. Only has about 15 rounds through it. Great gun, super fun to shoot on range day.  just wanting to go a different direction. comes with 3 mags. have the original boxes for the scope and gun.  I also have a sig romeo5 red dot sight thats never been opened id throw in for an extra $100.00 if you're interested. I think i have the original trigger still to if you want it.
