Very true, and if push comes to shove, I'll go ahead without it; but I'd like to have that luxury if I can have it. I'm thinking the AR15 lower receiver drill jig shown in this link would be my answer (as well as helping if I were to do an 80% lower in the future). http://www.cncguns.com/tooling.html (scroll down)LRBHO is pure luxury. It's not needed to operate an AR
Have you contacted the manufacturer or seller??Very true, and if push comes to shove, I'll go ahead without it; but I'd like to have that luxury if I can have it.

The website says: This AR-15 jig will also aid you in drilling the bolt catch hole as well. Simply slide the block with the slots (as seen in the photo) over the receiver and clamp them together with a C-clamp and you are ready to drill the bolt catch hole, nice and straight without worrying about a crooked hole and ruined lower.
Has anyone here done any business with this outfit before?
Mind, even if you drill it @ an angle or in the wrong place, there's still a chance to fix it by drilling a larger hole in the correct place, drilling a larger hole in the LRBHO, and using a larger roll pin or screw. So you get more than once chance to fix it. A lot of makers thread the hole these days and use a screw instead of a roll pin.
Use a PO money order - he reneges on that, you have recourse to the Postal Inspectors.
All excellent points. Thanks guys!The "jig" is just a piece of steel with a hole drilled the correct distance from the edge. Easy enough to make. Just clamp it to the lower in the correct place and use a long(6"?) drill bit the correct diameter. If that doesn't make sense, google some 0% lower instructions.
Finally got out to the range with this FMK for a shakedown and function check. I had some feeding issues with the first magazine I put through it but after that, it was clear sailing; put a couple hundred rounds thru it. I wasn't trying for bulls eyes (not that I could anyway) but nonetheless I was pleased to be ringing steel at 100 yards.
...and <drum roll, if you please> it's done!I've got one more lower to build -a forged unit, not an FMK- but it apparently the QC checks weren't done on it. The hole for the bolt catch is missing and I'll have to figure out how to drill it without effing it up.
I'll probably have to find a jig, there's no way I'm going to try this without a guide of some sort. Here's a pic of the hole i'm talking about:
