Not more than 100 rounds through it and have a bunch of Pmags to go with it. Works perfectly. This is essentially what the AR10 should have been. $1800. Comes with Ruger cloth case, a bunch of Pmags. Might consider selling a Leupold VX-R Hog 1.25-4 20mm scope for an additional $500. $2,300 takes both and a bunch of Pmags. PM me for more info. No sale and it goes to Texas Guntrader.
