Eye relief for 1903 A4 w/ Weaver K2.5?

[PhillipM]

If someone would post the thickness and spacing between the rings I will measure my K2.5 and we will see.

I would love to be able to help you out Phillip but I won't be home until Friday afternoon. If I can remember I will get you the measurements. Thanks, Rick

Question time,
Would the eyepiece end be unscrewed from the tube of the Alaskan and then the tube slid through the rings for mounting? Would that also apply to mounting a M84 using the same type of rings? I happen to have what I think are 7/8 inch rings for the Junior mount. Each ring has a reducer in it to enable a 3/4 inch tube to be used. I have not unscrewed anything at this point because I do not want to make a mistake and damage my scopes. TIA........George in NH

The M84 is nitrogen filled and sealed . You do not want to unscrew it . That is why you must use the two piece ring with it.
I believe you are correct on the other scope , but wait for conformation from another who has had one.

I have a K2.5 El Paso Tx. (early moving reticle post and horizontal wire) mounted on my A4 will try and get some pics the next few days..

Currently, with the rifle in the fired state the back of the scope is approx 1/4" to the rear of a vertical line drawn up from the cocking knob with eye relief being approx. 1 hand width back from there so eye relief is approx 3 "

looks like you might be able to mount it forward of the front ring but the eye bell and lock ring come very close to the mount and the aft ring will be into the threaded portion just before lock ring for eyepiece as the adjust block on my 2.5 measures 1.150" and comparison measuring puts the back edge of ring on the 3rd. thread hey that might also make it so the safety can work..

mine isn't sighted in at the moment so give me a few days and I will try the alternate mounting and post a pic

I've measured my Weaver K2.5 60-B. From the ocular bell adjustment threads to the adjustment turrets is 3.550". The adjustment turret is .980", adjustment turret to front is 3.050".

Eye relief on mine is approximately 3.70" - 4"

Therefore to put the adjustment turret in front of the front ring the outside to outside dimension of the rings cannot be much over 3.550" I have about a 1/4" of threads exposed I suppose could be put under a ring. Just thinking, an 06 round's max length is 3.340" and I know the rings have to be further apart than that on the inside dimension so I don't think it's possible.

well without removing eye bell and lock ring or bending a scope ring open this isn't happening... not really interested in bending a scope ring open and not sure how I am feeling about disassembling a scope

perhaps a braver soul than I will chime in...

whats the going rate for a K2.5 (early model with moving reticle) these days ? I gave $40.00 about 6 years ago and "rescued it" off a Bubba'd M1917 rings and all..

Oh yes. Removing the eyepiece and sliding both rings on from the rear is a given when using the top split (one piece) rings. Its the only way to do it whether you install one ring or two.
Sealed scopes like the M84 absolutely require the use of two-piece horizontally split rings. But thanks for looking anyway.
