Quick and Easy DIY AR-15 Upper Receiver Vise Block
I needed to install an AR-15 barrel on a new upper and didn’t want to pay $25 for a vise block. Instead I used some scrap 2x4s and a few screws to make my own.
This took about 20 minutes of measuring marking cutting and screwing to get just right. It’s a little bulky and could have been cut down, but ended up being far cheaper than one I would have had to buy!
