Has anybody had any experience with this brand, or this particular product? Are there better jigs out there for less money, and does it have the proper size drill and taps?

Also, one of the reviews said to get a tap bushing, but only one of them said to get it, do I need it?

Yes, you should get the tap bushing.

It holds the tap in perfect alignment with the drilled hole, and will go far in preventing broken-off taps in your rifles receiver you can't get out.

Was it me, I'd spring for the Forster jig.

Looks like the old B-Square jig. Works well enough when you use it correctly, but I now use a Forster jig. With either you MUST have the bushings. Don't even think about trying it without them.

okay, that Forster is WAY too expensive. Are these the standard thread sizes, and can somebody give me a link for the tap bushing?

Drill and tap bushings -
Pick the set you need for the particular screws that you will be using.

Brownell's order line - 1-800-741-0015

Above all else, be sure to use a depth stop so that you don't drill through into the chamber. Replacement barrels are expensive and labor intensive to replace.

I am planning to use that mount, it says it is a "Mauser 95" mount, but will it work on any small ring?

EDIT: I just followed my link, it didn't take you directly to that exact mount, but it says Mauser 95, you might have to look for it.

What thread size does Leupold use?

Also, what will happen if I drill all the way through, if I don't have a barrel in it? How deep should I drill it? And, will those Forster bushings work in that Sun Optics jig?

Would this work as a tap bushing?

Does Leupold use 6-48 thread size for their bases? It seems that they use 8-40 for the rings, but I don't know about the bases, although Brownells sells 6-48 "Base screws" for Leuopld...

6-48 is the industry standard for scope mounts. You will need a # 27 or 28 bushing for the tap. Some taps will work with the 28 while some are a little oversize and require the 27. To be safe, order the 27.

Who knows??

Only The Shadow knows!

Umm.... Midway says that the #28 is for the 8-40. The #31 is supposed to be 6-48...

Okay, how deep should I set the stop, or how deep should I drill into the receiver?

Mauser Lover, you really need to get some basic gunsmithing books.There is lots of very good advice here on The High Road, but nothing beats having good text to work from,

Youtube is great source, as long as the information is correct.

Others can list current books//

Okay, just one question at the moment, will a Leupold one piece scope mount for a Mauser 95 fit any small ring Mauser?

It should, right?

I have had no experience with the Sun Optics set-up but I am a BIG fan of the Forster gig that I've used for over 35 years. I use it with a full size drill press. Also use two taps in the proper size; a starter tap and a bottoming tap(with plenty of lubricant such as "Flute Juice").

Okay, two taps. I am guessing that the one that it comes with is a "starter tap"? Should I also use a second drill? How deep should I make these blind holes?
Is there any reason that I can't go all the way through the receiver? (assuming I don't have the barrel in)

Also, it seems like many places sell drill/tap bushings, can you use the same bushing for both tasks? Or are they selling a set of two?

Anybody know about that mount?
