This vise is good for a $40 vise, but they have problems as a result. I ordered this vise to complete my 80% lower AR-15 receiver and it did the job, but it was a bit awkward. This vise allowed me to finish the 80th lower part (I wouldn't have been able to without it), but I'd rather spend the extra $40 on a better quality vise. If you want a cheap vise this will do, but I would recommend a better quality vise for a more precise application. PRO: - Sturdy build, heavy and easy to grip - Holds up well if you don't make a mistake while drilling - Inexpensive CON: - Very high tolerance, oscillates a lot, can move half an inch while drilling - If the drill bit slips while plunging with a drill press , it will shift - turns well in one direction, but not the other - the packaging is not very
