    So my Marlin 30as 30-30 lever gun is having some issues. Since I got the gun a few months ago the stock sights were off. I was forced to put a scope on it because it was just soo inaccurate without it.

    How can I fix the iron sights? It shoots low and to the right consistantly.

    Would an adjustible peep sight fix the problem? Does it need to go to a gun smith?

    Thanks.

    If the issue is with the rear sight then YES an apeture rear would cure your issue

    if not a peep sight may still offer enough adjustment to correct for a canted front sight

    I would certainly have someone knowledgeable look at it to determine what the problem seems to be. It may be a simple fix that you have overlooked.
    Good Luck.

    Call the manufacture & see what they say. They will probably have you send it back to them to adjust.

    Sure you're not just flinching? Low and right is a common symptom of flinching.

    If it is shooting to the wrong place consistantly then adjust the sights so it shoots to point of aim consistantly. Sounds like you need to tap the rear sight to the left and raise the sight ladder. Before you get too crazy adjusting the sights you might want to try a different brand and weight of ammo.

    How much experience do you have shooting open sights? It is a learned art. Practice helps. I keep in practice with an air rifle. I have sent far more pellets downrange than any other projectile.

    I agree - try adjusting them. If you're out of adjustment on your sights and it's still not shooting to point-of-aim, call Marlin and have it fixed (if it's new).

    Thanks for the advice everyone. I'll try to mess with the sights a little today, and it that doesn't work I'll get it checked out. I don't think Marlin will cover it since it's 21 years olds, but who knows. :D

    First of all, distinguish between 'inaccurate" and "not zeroed." If the rifle is shooting large, irregular groups it is inaccurate -- and that's not the sight's fault. If it is shooting reasonabley small groups, but they aren't hitting near the aiming point, the rifle isn't zeroed. You can't correct inaccuracy with the sights.

    To zero the sights, raise the rear sight using the stepped elevator in the sight. This should allow you to correct for elevation.

    To correct for windage, get a small brass or nylon rod, place it against the sight dovetail and tap it gently with a small hammer. Since the gun is shooting to the right, tap the rear sight to the left. If that doesn't quite get it, you may have to tap the front sight over a bit. Tap the front sight to the right -- the opposite direction from the rear sight.

    Check the upper rear corner of the receiver -- you may see two small screws there. If so, those are filler screws for the receiver sight mounting holes. Simply purchase the appropriate peep sight, unscrew the filler screws and screw on the peep sight.

    If there are no receiver sight mounting holes, you can use the scope mounting holes -- order a Williams 5D receiver sight (# 774-488) available from Midway for about $35 - $40.

    You might also try these ... MUCH superior to standard iron sights

    I have one on my Puma lever gun in 45Colt / 454 Casull and love it.

    Vern, check your directions. Don't you chase the hole with the rear sights? ie. Move the rear sight to the right and/or the front sight to the left to correct for shooting to the right.

    Just the opposite. Chase the target with the rear sights. Chase the hole with the front sight.

    If the gun is shooting low, raise the rear sight (or lower the front sight.) If it's shooting to the right, move the rear sight to the left (or the front sight to the right.)

    Move the rear sight the direction you want the bullet to hit.

    I would have a good rifleman (probably some old guy or military) shoot it a few times before blaming the rifle.

    I'm kind of in the same boat.

    I have a brand new 336C that came with the front sight base offset just the slighest bit to the left side of the barrel. It was shooting good, tight groups but over 2" to the right. I was afraid that I would not be able to adjust it enough to sight it in, but by moving the front sight to the right just a bit past flush and moving the rear sight to the left quite a bit, we actually got it sighted in for the most part before running out of day light. The only thing that bothers me is you can see the front sight base is canted to the left when looking down the barrel and it bugs the heck out of me. So I have to decide if it worth the hassle of sending it in and getting back a rifle with lesser wood. I REALLY like the wood on mine. Marlin said I could take the wood off before sending it if I wanted to keep it in case they have to replace the rifle. I'm thinking they could just tweak the barrel to the right ever so slightly, but it may not be that simple.

    sleepyone,

    Keep the wood and send it back. You will be happier in the long run.

    Vern, thanks. I had a brain fart...of course you chase the target, I knew that. :banghead: I had too much time off work and didn't get to go to the range for any of it. My brain's still not all the way back on. :eek:
