Up for grabs today is a built sig m400 tread. This rifle comes with an enhanced full auto bolt carrier group, Midwest industries free float quad rail and barrel nut, magpul 2 point sling, enhanced trigger spring kit, daniel defense rail covers, scout light clone, magpul minus flip up sights, 30rd pmag gen 3, and magpul vertical fore grip. Will also come with everything from the factory including box and docs. Rifle has less than 500 rounds put through it and runs like a top. Will cycle any type of 5.56 or 223 and will shoot like a tac driver. All together, the value of this rifle is $1545 after all of the after-market parts. Only reason for getting rid of this is I’m thinning out the heard.
