    Mup jig

    Posted by Ishnifus on Jun 23rd 2022

    Shipped fast, Lil more than I wanted to pay but been on the hunt forever, and coupled with a fcu the discounted price wasn't bad. Did show signs of surface rust in a couple spots which I wasn't happy about but luckily on surfaces not crucial to jig operation. So aluttle tooth brush and oil and good nuff

    I haven’t used the jig to make a fire control unit so this review is just on the jig itself. Some of the markings indicating what size drill bit to use for a certain hole are very faint and hard to make out. Also, all the drill bits came in a single plastic baggie. The larger drills are marked as to their size but the smaller ones are not. It is hard to figure out which is which. There isn’t much of a difference between a #39 drill bit and a #40 drill bit. Wish the drill bits came in separate baggies with the size indicated on the baggie. At this point, I’m just guessing.

    If you take your time, you won’t be able to tell the difference and you’ll be asking yourself whether it’s live, or Memorex.

    I was very happy with how easy it works

    Getting the tabs to lay over right is a bit of work, but overall the rest was pretty simple. This is by far the easiest 80% I've ever done.

    Awesome tool!!!

    This jig is awesome!! I've never done an 80% before, and this jig was easy. It's built to last as well, even after hammering the top to bend the taps, you can barely see the marks from my hammer, and I pounded that thing, too, lol, probably more than I needed to!! So while maybe costing a bit more than a Glock plastic one, this will last you a long time, and of the quality and build more like the 1911 jigs. I will say, if you are new, and not used to running a drill press, buy extra bits. I burnt up the #40 (Ace has them, Home Depot didn't). It's not that the bits are cheap or anything, at all, just that its easy to put a tad too much pressure on it, not have enough cutting oil, etc. All the other bits are still good to go, I just got too excited with the little one, and of course I only had 2 more holes to go!!! Eh, it happens.
