Old Weaver .22 scope help needed.

Vulcan Bob · Jul 13, 2014

Hi all, just purchased a very nice old Mossberg 46M-B with a vintage Weaver scope on it. It's a Weaver, El Paso Texas, G4 . One of the long skinny .22 scopes that used to be the norm way back when. The question is that the knurled adjustment knobs come up thru a plate with a screw at the top, with left and right and up and down arrows stamped into the plate., not the kind with a removable cap turret. Before I monkey with it I would like to know what I'm doing first. I would assume the screw is a lock screw and to make an adjustment one would loosen the screw and then turn the knob. Posted a pic of it I found. I know, sort of a stupid question but I'd rather ask before someone said, whatever you do don't mess with that screw! Any input would be appreciated!

I have a B4 Weaver scope that I bought in 1959 on a Rem 514 22, I dont remember having to loosen a screw to change the impact of the scope, yours may be older than mine. Jeff

I hated those old 3/4" scopes. The eye relief was to exact, meaning it took too long to get you head in the right position to see through them. Also, the cross-hairs will move inside as you make your windage and elevation adjustments, so the cross-hairs may cross way down in the corner of the scopes sight picture. And, they call 'em the good old days.......yeah, right

The cross hairs on my B4 stayed centered and the tube dia. was under 3/4", maybe 5/8" but it was a very good scope and I got a lot of crows with it. Jeff

Thanks for the reply's folks! Well it may be a moot point, figuring the last owner had it zeroed I got out to the range today and shot it. Shoots a bit high and right but the zero appears to wander an inch or so between groups and the adjustment turrets appear to frozen. Too bad as the scope looks really good and match's the late 1940's vintage of the rifle. As for the rifle its a tack driver with the aperture sights. Well I may get a modern 3/4" scope to replace the vintage Weaver as those aperture/peep sights are rough on the eyes with that target aperture disk. These aperture disks unfortunately are not interchangeable with the new Lyman's and Williams. Yeah, I know, those 3/4" "sewer pipe" .22 scopes are horrible but I want to keep the "look" of the old girl.

Those old Weavers are repairable as long as they aren't damaged.

The cross hairs were screwed up in the weaver scope on this beautiful old girl but I did a little research, asked a few questions on another site and was able to make the repairs myself. Now she will literally shoot to the same hole out to 50 yrds. if I do my part. I don't mind looking through these old scopes at all.

Thanks. The only thing that is missing is the hood for the front ramp sight. I'm having trouble finding an original.

I found a b4 in an antique shop for $7 the other day. It cleaned up nice. Missing the tear drop caps for the adjustment screw turrets. I have tried to find a diagram online for these. No luck.

I bought a Winchester 190 at a shop a few years back, had a Weaver B6 on it. Magnification was ok, but I really didn't plan on using a scope on it anyway. Took it to the range, the adjustments had no effect on POI, good thing I didn't plan on using it! I do have a C4 on my Dads Winchester 69, works fine, only thing negative is that they used plastic ends on both the front and rear and made the diameters bigger, I guess to make it look more like a big game rifle scope. I preferred the B series with the straight, all steel tube. They were about $10 back in the day. Thinking back on it, I wish I'd not put a scope on that rifle, had to be drilled and tapped for a side mount, and I've lost the original receiver and front sights. Young and dumb, had to have a scope!

Just a note, the screw slots on the adjustments were for moving the adjuster, not locking it, as I recall. Also, it was necessary to tap lightly with the wooden handle of the screwdriver after turning the adjuster.
(We use to see a few, long time ago when many buffalo roamed the plains)
