Scope Bases

[SavingNolanRyan]

I have some Weaver style scope bases and the Rings I have the base screw goes all the way across the ring. I need just the slightest bit more adjustment and with the rings I have they have to fit in one position due to the slot cut in the base for the tightening screw in the ring base. Are there other rings that don’t use this center screw that can use more of the adjustment range on the scope bases or is this something for recoil to prevent the rings from moving? If so, I will need to opt for a scope with more room between the lenses.

Sorry if my description is not that great. My rimfire uses a dove tail and the rings can “pinch” anywhere on the rail.

This other rifle the bases are set in one position and with the rings and the base screw there is one position for each ring. That doesn’t give me enough room to fit the scope I want to use. Outside of a new scope are there some other rings to look at?

I use a picatinny rail on my rifles to give me the best chance of setting eye relieve,can see fairly well but multiple eye surgeries makes it a bit difficult to get the eye relief just right.

There are offset bases. I have to run then on my Weatherby.
Take your front base and match the screw holes to one that has the offsets in it.
A local gun store is usually willing to help you. Box stores are more hit and miss about opening the package.

There are offset bases

There are those. You can also google search Weaver offset rings. They make sets with one offset/one regular, or both offset. I've used them a bunch on long action Savage rifles.

I had forgotten those. It's easier for me to find offset bases where I am.

I haven't seen them in a shop in forever (maybe BPS/Cabela's has them?) but I've had good luck finding them online. I went with them on the Savages because I was worried whether the overhang of the offset bases I found would interfere with brass ejection. Found out later it definitely won't, so either approach works fine.

Some bases (two pc type) have a single slot per base.
Sometimes it's in the middle, sometimes it's more toward one end (so you can flip it around for some variability in ring spacing).
If it is aluminum you could file a new slot where you need it.

Assuming there will be enough shoulder for a recoil stop.
When using cross slot rings the ring's cross bolt is pushed to contact the edge of the slot, toward the muzzle.

Have over the years modified some bases using a #1 mill bastard file.
Birchwood Casey aluma black makes the mod look decent.

And yes, any new slot I added was same width as the factory slots, and square

IMHO it's just better to buy a pic rail.
Many rifles are not open top receiver anyway (esp entry level rifles).

My problem with one scope base isn't the number of slots or their position....the base itself isn't long enough at the rear (to move the ring back a bit).
I think EGW might make one. The Weaver on my old 760 has the scope turret body against the rear ring.
Had wider alum rings on for a while, went with thinner steel, still could use a tiny bit more rearward.

Looks like the EGW doesn't extend back any more than the Weaver, but being multislot it appears per the drawing to have the rearmost slot maybe 1/8" more to the back.

Could widen the Weaver and just rely on the front ring acting as a recoil stop.

In my best Steve Martin impersonation..........NAHHHHHHH

An extension ring at the back would alleviate the problem.
However this is an old 760, so has no raised comb.
To use it scoped I am running low Burris Zee rings.
Not bad like that.
Certainly do not want to go any higher.

Also, never been a fan of Weaver rings. They have been around forever, and are not pretty.

Burris Zees are just nicer IMHO.

Seen some rather nice rifles wearing cheap Weavers..........normal ones. Never understood that.

You never said what your application is? For all intents and purposes the venerable Redfield style dovetail mounts only had the front ring clamped into the base. The rear ring just sort of floated in a shallow recess between the 2 windage adjustment screws. Not the best system for a hard kicking magnum but for most everything else it worked fine for 75+ years. If your rear base is somewhat tight in the slot it might work for you OK.

I set my Pic rail and Weaver type rings where BOTH have the crossbolts against the forward slot edges.
No probs.

Maybe one is all I need? I'm not going to test for that

IIRC theRedfield/Leupold dovetail front/windage rear.......the windgage screws were relieved such that the head did cup a recess on the rear ring. And they were torqued down once alignment was done.
Of course the front being dovetail, had nowhere to go.

Lots of people don't put Weaver type rings on correctly and anvil the slots.
Saw tons of that when my state was slug guns.

 

[Hookeye]

From .223 to .300 winmag, and slug 12 ga...........alum Weaver or Pic rails and Burris Zee rings.
Dozens of combos. No probs.

 

[Hookeye]

I do think some older rifles look way better w the Redfield/Leupold dovetail front/windage rear setups.

I spent some time rotating the bases and carefully mounting the rings (Burris with Posialign inserts). I am using all available space (4.8”) on 2x7x33 Leupold VX Freedom and I am happy with the way it is mounted. Relief seems right, (as I have no room for adjustment). My only concern now is the rear base was tapped for one direction. Flipping it to make room I can only use one mounting screw not two. Will .30-06 stress only one screw? IT feels very solid but would prefer that second screw to be used.
