Adjusting fixed parallax - Konus AS34 2-6x28

[Scouty]

I ordered this scope for my P-Rod thinking it had adjustable parallax down to 10 yards. Turns out that was another Konus model. The AS34 has parallax fixed at 100 yards. Unfortunately I didn't figure this out until after it had shipped so I figured I'd probably just return it.

But I got the scope today and it really seems like it's an otherwise good choice for the P-Rod. It's inexpensive, compact and has the right eye relief for the folding stock I have in mind (I'd like the back of the scope to be more or less even with the hinge point of the stock, like my Leshiy Dedal combo).

I watched the AirgunWebTV episode on adjusting fixed parallax scopes and decided I didn't mind possibly having to toss the scope if I messed it up. 

So I took off the flip up cap and saw that it had a seam. The objective ring was already loose and as I turned it I saw no inner ring or parts moving with it.

Unlike the scope in the video the two notches are recessed about 1/4" down towards the lens.

Does this sound like a scope that can have the fixed parallax adjusted?

Do I need a special tool to reach down to these notches?

I'm still new to all this and I find this a tough subject to Google or search on this forum. Lots of info about adjusting parallax but not for fixed parallax scopes.

I'll post some pictures.

First is the scope with the notches visible behind the removed objective ring.

Next is the scope mounted on my P-Rod. The scope has a built in mount. If you flip the rails they are dovetail on one side and picatinny on the other. This is the scope mounted with the dovetail. Too low for a magazine. Will need a riser (or a single shot tray).

Next is the best I could so with a couple of dovetail to picatinny adapters and a picatinny riser. Magazine in place this time. Higher than I like but I wanted to try it.

And here is the video I watched. Information about what scopes can be adjusted starts at 3:10.

I recommend you contact Konus. I have adjusted the parallax on Leupolds and Redfields successfully but when I tried to do it on a Konus I found the lens carrier was glued to the locking ring. I actually turned the entire locking ring and carrier out past where I needed to be and wrapped the gap with waxed dental floss and tightened it. It took a few tries to get it right but worked. The ring/carrier assembly has to be tight or there will be poi changes and whenever you readjust you will most likely have to rezero. Unlike a scope with adjustable parallax which moves the lens forward and backwards without rotating the lens, this process rotates the lens and unless the lens is ground perfectly and positioned perfectly in the carrier poi will change when rotated.

Like Gary said the lense might be glued to the adjuster, but if not here is the tool you need to make like easier

Thanks to both of you. I finally got an email through to KonusUSA this morning. I was having trouble with their integrated contact page last night.

I found an adjustable pin wrench online at Harbor Freight but I would have to grind the pins down to fit in the notches. If Konus says it's possible I'll just order that lens spanner from Amazon.

I have a bit of free time this morning so I'm off to Cabelas to see if I can find a riser.

Over the years I have adjusted a lot of fixed power scopes. Some of them I just used my hand to loose the ring on front. Then turned the lens carrier. On a few I actually use a wrench, which was risking damage, , but it worked. My last one to change, was a Bushnell Prime, 3-9 with illuminated dot. On that one they glued they lens carrier, I had to heat it & it finally moved. I would not recommend doing that, but I now have a scope the is set for 35 yards and is very useable from 10-60 yards. What ever you do not move it so far forward that the nitrogen will leak out.
