RWS 34 scope mounting-need help

[El Greco]

Hey, probably stupid question but I am trying to mount my new scope but it's a bit more forward than I would like. The base has two deeper holes and two swallower but that screw in the back only allows me to place the one piece base and the pins in the swallower holes and not further back in the deeper as I would like. Is that big screw removable?

Sorry forgot the pic

Christos, I'm going to be so bold as to say you can remove that. i think it's just a filler for for a screw hole that a peep sight can be mounted on.

My D48 had no screw there, just an open hole which my rear scope mount now sits over.

I'm going to be bold as well and back up Jeff's suggestion. Just be sure NOT to use that threaded hole as a stop for a scope pin as it will mess up the threads if the mount shifts.

Also, label and keep that screw as I believe they are difficult to replace.

What is the year of make of your D34?

Thanks guys. I removed it. It doesn't seem to hold the rail to the tube underneath.
The scope by the way is the Hawke airmax 30 sf compact 4x16x44 ir.
The rifle I got I believe a year or two ago. I like this platform.so much that last night I ordered the compact version as well. I am trying to make my Parrus work but longer sessions do take a toll vs my 34 that I can shoot for hours. Thanks for the help.
By the way for the pro compact I ordered a UTG scope with a 50 mm objective.
I like big scopes and I cannot lie

FWIW, Dennis, I thought that was true about those screws, too. But after measuring them with my metric thread gauge and some research I found them to be nothing more than M6 0.50 thread screws. I sourced some for my now removed rear sight screw holes from a company that sells metric screws... the ones I got are used in laptop hard drives. They're perfect for filling such holes, 4mm long with a very thin head and black. I can provide a link if you want.

For those with inquiring minds who really want to know - those little peep sight mounting screws are not included with ALL new Diana rifles, just most of them.

Thank Jeff - Good to know, but I still try to keep all my original screws labeled and available. In my older years, I tend to lose them, and not just the screws of my airguns IYKWIM.

That's interesting. 

What do you suppose makes the difference as to whether they're included or not? Perhaps the particular Diana factory worker didn't have his strudel that day?

Oh I know what you mean, Dennis... which is the main reason for my post here: I gave the wrong screw size cause I forgot.

The screw size is NOT an M6, it's an M3... and the specific screws I used to fill my rear sight holes were: M3x4mm, 10026NP.

Ordering those was complicated, it took multiple websites to determine the "NP" part, which meant it was black zinc coated. I didn't want silver ones.

The website I got them from was: https://www.laptopscrews.com/M3x4.htm
The website I confirmed size/color was: https://www.metricscrews.us/index.php?main_page=product_info&cPath=98_7_62&products_id=186&zenid=9qv2t66bi1ovm5ckjl82tllqu6

It has been a time with my D48, trying to find and get many things... then using them and changing them and and, it leaves me spinning by day's end sometimes. I first found the size by measuring and comparing my rear scope screws. Got some socket cap screws from Home Depot, but too long so I cut them to fit. Open screw holes were gone but gun had two warts on it now. Started searching, found what they were used for so searched my spare computer parts and remembered... I'd thrown out the last laptop hard drive last month after determining I wouldn't have use for it so took it apart, took magnets out, and tossed it. So... back to the web, but it took a while to figure things out because they'd changed part numbers but by cross checking I found the "NP" suffix meant Black Zinc Coating. Ordered them, and waited. That's just one part. There are other ones that didn't turn out so well.

Wish I could put my thoughts into little plastic baggies and label them for later use. I "lose" a lot of things these days...

Regarding the Diana scope rail - it may not be common knowledge but those little Phillips head "screws" holding the rail to the gun are not screws at all, they're rivets.  If you use the two deep holes in the rail for scope stop screws as intended do not over tighten the scope stop screws.  They are pressing directly against the compression tube and the pressure from the screw against the scope mount can pull the scope rail loose from the gun.  At that point the scope is no longer stable.  On a break barrel Diana it's not a big deal replacing the compression tube.  On a fixed barrel it would be a disaster as the whole thing is one piece.

Thanks Roadworthy and appreciate the guidance through pm.
Unfortunately I didn't have that info last night when I mounted my scope and I can't remember how tight I torqued down those screws ( didn't use a torque wrench as I usually do) as I did it by hand. I don't want to take it off again cause you all know how much time is required to get the crosshairs perfectly level...
Today I am going to sight it in. I am guessing once that is done and if after 20 pellets or so the POI is not shifting it means I am good.
The new Hawke compact scope looks amazing but the way. Can't wait to see how it holds up.

Hey guys,
Posted the question at the scope gate but haven't gotten an answer yet. I sighted in the scope earlier and it shoots bullseye at 23 yards. My question is if I am close to optical zero or at this setting I am too far off?

So in both elevation and windage there are 5 graduation lines and in both I am sitting just below 3
