Need advice on breaking the screws loose on the scope mount scope rings and crude adjustments screws.
I have tried and they seam frozen in place. |

I really don't want to get rid of it. It reason I want to adjust the crude adjustments is because at 100 yards I can not get it sighted in Set the scope elevation and windage at 0 and start at 25 meters. See where the rifle is hitting and make adjustments as nesecary as you continue working your way further out. What kind of ammo are you using? Remember that these rifles were set up by a skilled armorer who knew what they were doing. I remember your rifle, i almost bought it. I also remember that the mount was matched to the rifle. Make sure that the mount is properly installed in the base, sometimes it takes a bit of force to get it to fit in if the elevation screws are snug. Use a screwdriver on the big thumbscrew and make sure it is nice and snug. Make sure the witness mark on the scope and the mount line up with each other. Make sure the action screws are snug on the rifle. Do not mess with the elevation screws or anything else! It sounds more like inexperience than the rifles fault. Be patient and the members on this forum can walk you through this. |

He might be onto something. I just sighted mine in and I had to set it to 800M to get zeroed at 100 yards.
My windage is off, as well, but not too badly. The windage is useable as-is, but the elevation has to be corrected, for this to be used at any sort of range. I'm tagging for answers. I had to play with it a bit, to get the scope mount together, but it's solid. I suppose I could take it off and see if I can get it on better, but I think it's seated as-is. |

Is your scope mount serial numbered to the rifle? Are your elevation screws staked in place? Usually if the mount is matched to the rifle, then it will be dead on 99% of the time. I cant say ive heard of someone having trouble zeroing their PU with a matching scope mount. I have a PU sniper that came to me with a mismatched mount that was comically out of line. The mount was numbered to another rifle, not mine. The elevation screws were also unstaked and spun freely. I spent many hours grinding and filing on the scope mount pads to get the scope mount centered over the bore. It was a major PITA but i eventually got it dialed in and its now an excellent shooter. All of my other PU snipers that came to me with matching mounts had no trouble getting on zero right out of the box. Only very minor adjustments were needed. That is why i find it hard to believe that a rifle with a matching scope mount would be unable to get on paper at 100m. OP needs to be absolutely sure that it his mount that is out of whack before he starts messing with the rifle. |

Mine is serialed to the rifle. The rifle is zeroed at 100 and the scope is set to ~750 meters. The mount'a elevation screws are staked and I have confirmed they won't move under moderate force.
The serial is electro pencil, but I think that's normal. I have some windage dialed into it, too, but not as extreme as the elevation. The mount was VERY hard to get in between the screws and I had to force it into place. The whole assembly looks to be seated well and is solid. The mount is definitely off by a large margin, unless the score is broken. It holds zero just fine, though. It was able to shoot respectable groups with it, once it was zeroed. I know this is abnormal, but I don't know what else to say. SOMETHING is off in the setup. I suppose I can take it apart sometime over the weekend, too see if it looks like I did something wrong.

Yep it sounds like you have to adjust the elevation screws on the base. That is unusual since the mount is matching, but I guess anything is possible considering these were rebuilt by the Russians. Maybe your rifle was refurbished shortly after the worker received his weekly vodka ration
When adjusting the elevation screws, remember that a little goes a long way. Also remember that the screw threads may get chewed up when breaking the stake, so go slowly and as little as possible to minimize the damage to the threads. |

The "drunk Russian" angle was one of the first things I thought, too. I suppose it might have gotten a replacement mount and Ivan figured it would be "close enough". The rest of the rifle got a fer better treatment than most common infantry 91/30s got during their "busy work" refurb, so I I DO find it unusual that the alignment is that out of wack. My luck, as it often turns out. At least it's fixable, with some effort. Yeah, gonna take my time with this one. |
