    Zastava mount , ring , scope problem

    A young mate has bought one of the wooden stocked 223 Zastava's and a vx1 to go on it. nice wee gun
    The problem is he cannot get enough "down" on the scope to zero it, it's 4-5 inches high at 25 yrds
    The Mounts cannot be reversed as the screwhole gaps are different
    He was given what look like weaver, or weaver type mounts and cheap rings
    The back mount is higher than the front, but there is still plenty of bolt handle/scope clearance.
    I swapped the rings out today for a pair of my low Leupy prw's but that still left us 2-3" high at 25yrds.
    Anybody else had this trouble or any easy fix,I could shim the back one up but would prefer a clean fix cheers

    He cannot just take it back and ask them to sort it as he has had it for a year or more with a red dot scope and that was able to be zeroed

    Coke can shims would be the easy fix, otherwise take some material off the bottom of the front weaver block, then use epoxy to ''bed'' it back onto the action, the epoxy will fill any ''roughness'' and make sure it’s all aligned sweet. Then lap the rings to get them aligned correctly so you don't kink the scope tube.

    Sounds hard, but it’s a 20 minute job (plus curing time of glue).

    If I shimmed the front, or put a higher front, or lower rear mount, wouldn't that raise the poi even more.
    Not too sure , which is why I posted
    cheers.

    Re: Zastava mount , ring , scope problem

    Imagine the scope is in a vice on target. The barrel is pointing up cos its shooting high .
    To point the barrel down would need the front mount higher or the rear mount lower right

    Think iron sights for a minute
    The old 303 rear sight goes up a ramp for more range. Raise rear sight = raise poi
    Same for rings raise rear or lower front =shoot higher

    Yep, VC is spot on, to drop poi you need to raise the front mount or lower the rear.

    Oh! Yes you're correct VC.
    It’s been so long since I've had to do it I'd obviously forgotten which way around it was. I used to do a lot of air-rifle hunting and you could never get the scopes to the correct POI on an air-rifle with its rainbow trajectory so shimming was always a necessity...but that was 10 years ago when I was in the UK so my memory had failed me, thanks for correcting the mistake.

    Alright, we are onto something here, Thanks Cam , spud, kj..

    So do you reckon if i put a lower ring mount on the back with the standard size on the front, that this would lower the point of impact .
    But would it twist/bend the scope body unacceptably

    Ok I'll try that first. so shim the front mount up shoot and see
    As I said above I've tried swapping for lower decent rings and now we can actually hit an A4 sized peice of paper but still 3" high at 25.
    I've never struck this problem before where I can't get a scope sighted at 25yrds, it weird.
