Hey yall, im a shooter and reloader but dont know too much about gunsmithing if someone could please give advice? I own a newer marlin 336Y (remington era, remlin made) and i like the gun. However, i sent it back to remington a couple years ago for barrel alignment and they supposedly repaired it. Then i dinally got around to shooting it again and realized the barrel is a little better but still skewed to the left. Obviously this creates an annoyance when using a scope and when looking down through the receiver, i see the barrel goes out to the left a little. At this point, i spoke to Remington and Ruger. They said im on my own. So, my question is, whats involved if i take it to a qualified gunsmith? How much $ am i looking at? Obviously, im very annoyed but have nobody to blame except myself for not double checking remington's so called repair until now. Any insight? And thak you for your time.
 
You're talking it actually angles left, not just rotated CCW to where the sights are canted?

If that's the case, really no easy fix with a lever gun that has irons and features for the mag tube machined into the barrel. The shoulder would need to be re-cut with the barrel turning between centers, but removing material will cause it to index differently. It would have to be shimmed, and they'll be visible.
 
Correct. Not rotated, it actually angles out to the left a bit. Is very unfortunate to see a new gun have this
 
It sounds like the receiver was threaded off angle. If there was a factory left the right thing to do would be to return it. Since that isn’t an option there are a couple of other things that could be done. Bubba could bend the barrel slightly. Don’t laugh, it’s been done. Or a skilled machinist could set the receiver up in a mill and bore the receiver threads out, rethread oversized, and make a threaded insert to fit the barrel. Yes, very expensive.
Maybe someone else will have another idea.
 
Im guessing i gotta shoot it like it is or pay more than its worth to fix....how much is piece of mind worth
 
I had a Ruger Blackhawk like that once. It was used. I traded another gun for it and paid another $50. I took it back to the gun shop and they gave me my old gun back and the $50. They returned it to Ruger. Ruger sent them a new revolver which they could sell as new. It was a win/win for me and the gun shop.

Back in the day it wasn't unusual at all for the scope mounting holes to be drilled and tapped so that they didn't line up with the barrel. That is why Leupold/Redfield windage adjustable mounts were invented. Using that type of mount will allow you to mount the scope so it is aligned with the barrel. I don't know how far off your barrel is, and there may not be enough adjustment with those mounts to get everything lined up. But that is your best/easiest/cheapest fix.
 
I guess this makes my decision easy.....when deciding on barrel sights vs peep sight lol......barrel sights are gonna still be aligned. A peep wont
 
There are scope mounts that mount to the barrel.
They allow forward mounting an extended eye relief scope.
A recent fad...
This would compensate for the misaligned receiver.

I have seen many Marlin rifles with off center (rotated) barrels but never one that goes to the left or right. I have seen a few that drooped also. And all of these long before Remington stepped in to help Marlin build crooked rifles. Curious but have you physically verified that the barrel is not in alignment with the receiver by measuring it? I ask because sometimes through a scope (low power) the front sight will appear to be to the right or left depending upon your cheek weld or lack thereof and there is no misalignment at all, it is just optical.
 
Ive personally looked through the receiver with bolt out. Its definitely not straight. I wish i was wrong. Will check out the guy in CO
 
My brothers first 1895. 45/70 had horrible barrel droop. Remlin would not warranty it. I believe it was Wild West Guns that said they could fix it. However the price was outrageous. Far more than the gun was worth. If I remember correctly they offer some custom package deals and would have included fixing the droop in them.
 
Yeah...im thinking of just keeping it as a beater, a knock around rifle to use with open sights thats light to carry, shoots a nice 3 inch group at 50 yards with open sights and call it a day

I think this is a good idea. Eventually if you shoot it enough you will automatically learn to offset or use "Kentucky Windage" and be very proficient using it that way, as you said it can also be a beater gun and loan it to those less fortunate that may want to go hunting with you one day.

I had a 35 Remington that had the same similar issues like your but I got so good with it I had my buddies wanted to buy it from me. Finally sold it with him knowing about the problem, and throughout the years he has had many successful deer and hog hunts with it.
