decided to throw the 3-9x40 i had back on the 1322, but i had a issue with it. the windage adjustment knob had a edge to it that made the scope crooked when mounted on the scope mounts on the 1322. so first, i tried to angle the scope mount with a knife. when that didnt work, tried sandpaper in fine grit and heavy grit. it wasnt doing much but just smoothing it down. then i took a drill, and used the shaft of the bit to try to grind it down.that failed also, but ground it down a little bit. then i looked at the scope, then thought that i could grind the edge down a bit, using a part of the drill that had a dimond checkering that rotated when the trigger was pulled. using it as a makeshift dremel, i ground it sort of round. it was a bit uneven, but it was smooth and not rough. fitted it on it and it was centered perfectly. took about a hour for me to do it. the part was too big, i had to be very careful because it was awfully close to the windage knob. i used a black sharpie to cover it up, you can barely notice it now. went downstairs and fired about 20 shots, sighted it in, and got consistent hole in hole groups. learned something new about the scope too. i found the knobs had numbers that represented click values that actually worked. set the windage at zero level and the shots were in line with the vertical crosshair. set it to zero on the vertical and it was 2 dots low. i settled on about 3 1/2 and shots where in the center. will post pics after my wrists stop hurting.

Where there's a will and power tools there's a way. Nice work. :-*

I would never do a mod like that..I want my equipment unmarked and unmolested I don't care if I have to spend more..Regards.

that's just you though. I really don't care. if it works, then its worth it. the scope holds zero, it kills house sparrows, so that's all that matters.

I agree.  I have a Chinese air rifle which could never hit anything except at the distance I sighted in at.  Turned out the front and rear sights were never on the same vertical plane, so I took a grinder to the spot welded rear sight and mounted a UTG red dot using a 11 mm to Picatinny riser.  Nicked the barrel/tube a little :(  so I used the old permanent marker trick.  But now it can hit at any range although it just doesn't look right with the front sight always cantered to the right.  I don't know how to get rid of it so it stays.

Nice solution!
That must have been frustrating....grinding, checking, grinding, checking, etc, etc...

Some people don't have the funding to keep throwing money at a problem.  I like the fix and the only one it matters to is the owner anyways.  Plus the quarry is still dispatched whether the gun is perfect looking or has a few nicks and scratches.
