Finally scoped my M14...Massive Dissappointment

DSCF0345.jpg


Goth the same thing on my 2 rifles, both 2009. One poly one norinco.
 
I would assume if it was an issue with the pocket in would be on the right side front of the sight holes or on the left at the heel, pushing the mount to the left.
 
Dweano,

Shoot me a PM - I believe we're in the same area. I can help. I have various scope/ring/base-to-bore alignment tools and tricks (benefits of being a machinist AND an obsessive gun nut! And no, no lasers or voodoo needed:rolleyes:). By hook or by crook, we can get that thing straight for you! There's almost nothing that can't be accomplished with appropriate applications of metal manipulation.

I'll be very busy over the coming months but seeing as your school, etc is taking much of your time, I'm sure we can figure something out. Even if you just left it with me for a while, I could tinker when I'm home and have the chances to do so.

Hey Rooster! Yeah I am real busy with instrumentation like I was talking to you about at the clinic (turns out they don't just hand out tickets :D) anyways yeah sometime in the future I can just drop it off with you. I won't be using it for ...well...a long time so you can work your magic on it. I am kinda interested to see what Frank has to say about the mount I shipped back to him, I am assuming it was fine tho. I am still kinda of debating getting a promag copy of the ARMS 18 mount. They look a bit lower and they look like they would work real good with brass ejection and such.
 
Without the scope even on I can tell things are not pointing the right way[/QUOTE]

Ok my buddy had this same problem. We both bought a norinco m14 and the casm mounts to mount our scopes. My casm went on fine but my buddy had issue with the thing pointing off to one side. I took a look at it and noticed that his norinco receiver was not machined correctly and that he could not get the casm to sit square in the receiever. It was not pointing inline with the barrel and off to one side.

The fix is to look at the inside edges of the receiver to see if the corners are machined out completely. If the casm is missaligned and pointing to the right side of the barrel, the problem is the inside of the receiver where the casm sits. Remember casm's marketing is that it aligns itself with the receiver and becomes one, unlike any other sope mount system. That is where the accuracy comes from.

You can dremel out the area of the receiver that was not completely machined out. This will allow your casm to sit square with your receiver. It's a quick fix and takes little to no time to dremel out the bad corner of your receiver. Just take a good look at your whole receiver where the casm sits. You will identify the problem rather quickly and be carefull with your dremel. Take off a little at a time and fit by hand. You just need to remove enough material to have your casm run straight with your barel, you can hand fit the casm mount and eyeball this easily in between dremelling sessions.
 
This is an interesting thread. many of us have had scope alignment problems over the years and found solutions.

When buying a cheap scope, a fixed power is much simpler and more robust than a zoom. The insides of a zoom look like a watch. A 4X or 6X would be my choice, with 4X the most versatile.

The scope points to the left. If you buy Millet rings, you will find that the ring has a 1/4" of left/right adjustment.

It looks like your scope is pushed to the right, at the rear. A Millet ring could take this error out.

I set the scope to the middle of the adjustment range and then use the opposing screws (back one off, tighten the other) to move the hits to the center of the paper at 25 yards. Once hits or about center line, I Loctite both screws, tighten both and zero the scope with the scope adjustments.

The Millet mounts will take care of gross alignment issues.
 
Personally, why #### around with a mount that won't fit?
Dremel tooling away in the sight pocket? Hmmm I'd just get an arms 18 and call it a day ;)

Thanks again for your feedback Thomas but perhaps the simpler and far less costly fix for the end user would be to cut a small shim out of a feeler gage, put it into the right front side of the pocket where the machining on the receiver is noticeably off and problem solved.
 
Im thinking of getting away from my Sadlak Airborne mount and going with a CASM.My main question is is this mount more stable/secure then the Sadlak? Im currently running a SAGE chassis and i want to be able to put a BUIS on the top rail like H20Man's set up.Currently i cant use my factory sights anyway and i dont really like the idea of relying solely on a scope(scope breaks im screwed etc etc)Any suggestions?
 
Once Dweano brings me his setup, I'll diagnose and report. As for taking material out of the receiver, a little bit of "smoothing" or lump removal (as in excess, 'do nothing' casting lumps & bumps) is fine but generally, you want to keep material on the receiver. If there is excess material in the corners of the sight pocket, it's better that clearance is incorporated into the mount. I'll see if this is necessary only after I have a look at any possible shimming solutions.

Hey guys, yeah the last couple weeks have been...interesting, anyways...I am kinda feeling this solution. That promag copy looks sweet. I can keep the iron sights and it looks a bit lower mounted then the CASM. I do appreciate the offer 358Rooster...but I feel like it may be easier for all of us if I just get a different style ;)
 
Buncha damn quitters!:D

Hey Dweano, no worries. I'm always willing to help out if I have the time. Either way, I hope you get something to work. Would still really like to see what your ordeal looks like just to satisfy my own curiousity. And by the way, if you've given up on your Casm, I'll gladly test that sucker out for ya!;)

Study hard young fella! Instrumentation's a good gig and before you know it, you'll have some young mouths to feed (it kinda creeps up on ya when you least expect it, somehow!). Good luck buddy!
 
Haha I actually postponed instrumentation for a year. Working at a manufacturing business for a year. Anyways...Promag Arms #18 copy came...slapped it on yesterday...going to take it out and shoot some to see what it looks like. I am really hoping it hits on target. If so...Rooster you can have first shot at buying my CASM :D
 
Initial testing is showing great promise! I hit a target at 100 yards ish...further testing will take place when 30 mile an hour winds die down...side note...CASM for sale :)
 
Haha well...I think I am going to get some low rings and then take everything off and remount and tighten everything with loctite...then I will take some pics, dial in the scope, and see what I can do. The darn thing about scopes is that it really amplifies how much I can't keep the gun still haha. Shaking everywhere!
 
I reading your issue and seeing some of your pics reminded me of the time I mounted mine. The NC Star (very cheap and not worth the headaches) mounting bracket did not come with the shim, so I fabricated one and boresighted it.

I first checked to ensure the centerline of the scope ring was the same as the centerline of the rifle bore. With the handguard removed, a few marks with a fine sharpie pen verified that the mount itself was not mounting center to the barrel. I needed to shim it. Once the shim size was verified, I then checked to ensure the horizontal view plane of the scope was the same as the rifle bore. This was tricky.

Firstly, I counted the rotation (and then clicks) to center the reticle in the scope mechanically. I have a portable rifle work station, so up to the kitchen table I went. I leveled the rifle and secured it. My mount allowed me to use my irons, and they are sighted in, so I affixed my sights to the (vertical) edge of a building wall about 300 yards away from me. Then carefully set the scope in a tighened a couple of screws so the scope would not rotate. Turned out that the scope was about 6 or 7 degrees out (to the right - I think) and I had to tighten the knob attached to the (removed) stripper clip guide to adjust.

out to the range and some tuning vertically and very fine tuning horizontally. Sadly, I hated the extra weight and the different feel of the rifle on my shoulder. I removed that cheapass mount and chose to just go with irons.

I had this exact same issue with the elevation of a certain mount I was using. The front dip set screw had to be pushed down so far that it required a shim in the rear, and I had to fashion one in order for a 60moa scope to click down enough for 25-100y shooting.
