View Full Version : Older Rifle/Optics question

October 31, 2012, 10:06 AM

Recently picked up a Remington 600 (non-Mohawk) from the local gun guys here in town; after finding out about the trigger recall (and having the rifle dry fire after taking it off safe and touching the bolt handle) I sent it back to Remington to have the trigger/safey recall done.

In order to do so, however, I had to remove the scope. The scope itself is an older Weaver V4.5 with a T-reticle, which is actually pretty neat. However, the mounts themselves have me puzzled.

There are two round posts that the rings mount on to, and are then tightened with two screws on either side of the post. When I took the scope off, I was unable to get the rings back on the posts with out sliding one of them out a tad bit. Now they are back on, but having never seen this type of setup before (I assume it has been on the rifle since before I was born) I have no idea if I have mounted the thing correctly or not.

So, basically asking if anyone is familiar with this type of optical setup and how to get it at least mounted correctly before I start throwing rounds down range to get it zeroed.

Any and all help is appreciated!

A picture is worth a thousand words. And it will help figure out what kind of mounts you have.

True, that is an excellent point; that's what I get for posting this from my cubicle at work vs. sitting at home.

I will get pics up tonight.

Thanks again

Pics appreciated, but not needed - You most likely have the proprietary Bushnell Universal Post/Ring mounting system, marketed in the 1970's. (I had bought a set for one of my rifles, back in the day)

It was first introduced as a handgun mount for the Bushnell Phantom scope in the 60's, then as a universal rifle mount system.

Quite possibly. I don't remember the Bushnell one, I was thinking of the Tasco World Class mount system marketed in the late 70s-80s.

Here's a 1966-vintage ad for the Bushnell product:


IIRC, the Tasco World Class product had the studs built into the bottom of the rings, with corresponding recepticles/holes in the bases.

The Bushnell system was different, as with the OP's mount, with the mount studs screwed directly into the receiver, and corresponding recepticles/holes in the bottom of the rings.

IMO, the Tasco was a workaround the Bushnell patent(s).

That's the one!

That was quick, thanks for the help.

Love the old ad: "400,000 pounds of recoil resistance":D

I also noticed that the Scopechief II has the same Command Post reticle as my old Scopechief IV...
