if you are just assembling a lower you don't be putting much force on the parts. I've take scrap wood and shaped it accordingly to fit fairly well in the mag well and chucked it up in the vise.
sometimes it just isn't necessary to spend money
I took an old, junked steel 20 round straight magazine pulled the spring and follower slid a piece of lumber into it to keep from crushing it in the vise and twisting. Vola! Instant vise block!
