I have X-caliber's BART 2.0 tool, little pricey but watch for a coupon code on their FB or web site, will save you 15-20$. Awesome tool for lapping and reverse the tool and lock it to a vise to work on a upper, no stress on the upper itself. Little pricey but if you have multiple ARs and work on them it's worth it over the wheeler.
