I'm impressed! (28.10.2010)
I have MS and I've never been mechanically inclined, but I got perfect results using this fixture. I highly recommend it!
Easy to set up and use (24.07.2012)
The product drops into place, the sides are always parallel and the drill bushings are always centered. Some guns require repositioning of the fixture after each set of holes. A Mossberg 500 shotgun, for example. I have useed this on M98 Mausers, a variety of shotguns and a Remington M700 long action without a problem.
Excellent tool! (15.11.2013)
This has been used in my shop on everything from a Mossberg 500 to a Winchester 30-30. Sets up perfect every time and allows you to drill with confidence the first time!
Not perfect, but worth the money (19.08.2017)
I used it to drill and tap a 93 Turk Mauser. It was hard to center on the round receiver. I measured carefully, with a caliper, from the bottom edges of the jig, to the flat of the receiver, and got it as close as I could. I lined up the holes for the front base, and placed a crossbar in the farthest hole back, on the fixture, placing it in position on the rear of the receiver, for the front screw of the rear base. I measured carefully for depth, and marked the depth on the drillbit with tape, to keep from drilling all the way through. I used a high quality drillbit in a cordless hand drill. There is not a tap guide, but I left the fixture in place, to make it easier to see that the tap was straight. I started the thread with a regular tap, and finished it with a bottoming tap. The front holes were easy enough. I only got about one thread before I had to switch to the bottoming tap, because the holes are that shallow. 4-1/2 turns was deep enough for the screws that came with my Weaver bases.
Note to amateurs: keep the drill bit, tap, and hole wet with oil when you drill or tap steel. The tap should turn about 1/4-1/2 turn in, then back out that much, to clear the threads. Blow the metal shaving out often, and keep oil in the hole.
As I mentioned before, the last crossbar just happened to fall about where the front screw of the rear base should go, so I drilled and tapped that hole before I moved the fixture. The bracket on the left rear of the receiver, where the bolt release lever mounts, blocked the fixture from going back far enough to line up the right set of holes (.50") for the rear scope base I have. After starting to notch that rail of the fixture a couple different ways, I ended up just cutting a 3/8" square off the bottom corner of that one jig rail. That left all the holes for the crossbars intact and usable, and allowed me to move the jig into place to drill the rear hole. I used the drill bit as a pin to align the fixture with the existing hole, so the two would line up perfectly.
The fixture is good quality, and served its purpose well. Though I had to use a lot of care to align it, and then modify it to work on my receiver, I am happy with the results. First time use, start to finish, I took a couple hours.
