Finally scoped my M14...Massive Dissappointment

Hey guys. I finally got my CASM scope mount from M14.ca. Followed the instructions to the Tee (even watched the video). Put on a scope. I was careful to try and torque things just right (on the mount I did it perfect, I turned the front vertical adjustment screw just under a quarter turn after it hit the reciever) and the scope and rings I did tight but nothing excessive.

Alright so at this point we have a scope on an M14 (which up until now shot a 4 inch group at 100 yards with irons...irons aren't my thing I guess haha)

I head out to the Range (aka...our field) go out to 100 yards, take a shot, nothing on the target.

Alright way too far out 25 yards...take a shot...nothing! My friend saw it hit to the right. So I adjusted it left left left. Nothing. More shots...nothing. Etc. I moved up to 10 yards! How can I mess this up. Take a shot. Eight inches to the right. So I turned the scope adjustment ALL THE WAY to the left. Literally no more adjustment available. Take a shot at ten yards and its still an inch to the right.

OK whatever, back to 25 yards. Take some shots. Kinda getting on the target. Still to the right very much.

Go back to 100 yards. No chance of hitting the targets...but I let my buddy take some shots just for fun. I think I may have converted him to a GunNut. So...one success of the day.

So anyways...we take the scope off (which looked like it was angled to the left)...and we put a breaker bar (it was all we had) and it was not straight...a bit off to the left.

Scope appears to be fine...even tho it is a cheap one. But that shouldn't be the problem because it was visible that the mount was pointed off parralel

Rings appear to be fine

CASM mount...I haven't checked yet. But I doubt it, it seems to be a high quality product

So what then? is my receiver messed up? I got it from CanAm a couple months ago

I'll try to take pics later
 
What make and model scope and rings are you using

Did you use Loctite on all the mount screws to keep them torqued up

Are you sure your scope rings are tight, scope not slipping from recoil

Did you detail strip and clean your M14 before firing, or lately

When firing with the bipod, were you leaning forward into it all the time

Don't mean to sound condescending, but there are a few too many unknowns in your story, we need more data

Yeah I know I am a newb to this. This is my first rifle and my first adventure into optics. First off I am using a cheap scope which I know...don't cheap out on optics but it is what I currently have. I hope to upgrade in the future.

The scope is a crappy one...Tasco I believe, it doesn't say on it and I can't remember the brand...it may even be a knockoff. The rings were included (I know...TWK) but honestly the scope seems not bad and solid.

The mount was installed using Loctite on all screws. Scope and ring screws were tight but not loctited

I have fired maybe 80 rounds through the gun since I got it. After about 20 I greased it up

I was resting on the bipod not leaning into it or against it

It sounds to me like your sight in process is a bit flawed.

Yeah not the best I know. But I couldn't even adjust it left enough to get it on paper from 25 yards. The scope is pointing a different direction than the barrel.

I think I am going to try the dowel trick to see what things are lined up and what aren't.

As I said, I am new to rifles (well, centerfire...I have a 10/22 with a scope with I installed and sighted in the same way I was doing this) and I obviously need some help and probably knowledge :rolleyes:
 
Quite often with m-14's the install of the scope base has to be done with some shims......

You will need to square the scope base with the bore.

I had one that needed quite a bit of material added under the mount on the side of the receiver. Washers were not enough.... I wound up making a "bump" on the side of the reciever with JB Weld and then filing it down to the right thickness. It needed a much longer mounting screw.....

Millit rings may be what you need.

Zero the scope (turn knobs until there is an even amount of clicks side to side). Mount scope to base with adjustable (side to side) rings.use the scope elevation adjustment to get you dead on (up and down) at 25y. Use the rings adjustment to get you dead on (side to side) at 25y.

Try it at 100y. You may find that your scope or bases may need adjustment.

This is a short term fix. You will still need to do something about your mount. But at least this way you can get shooting untill you do....

Without a properly installed base on the rifle, and decent proper rings you will only be able to zero the rifle for a particular range. Your come ups and windbags adjustment won't work properly.

This is a common problem with the platform.

Cheers!
 
Take a broom handle and set it on your mount. If it is pointing that far to the right, you should see it with the broom handle. It is entirely possible that the mount itself is pointing right.

For a first experience with scopes, you chose the worst possible rifle! On my M305 I had to purchase 3 mounts before I found one that was ok. The first two were misaligned. Could have been a problem with the rifle itself...

Another thing you could try is to flip your rings. I have seen some rings that are not true so flipping them actually moves the scope. Try all combinations.

To avoid wasting time and ammo, aim at a straight line from afar using your iron sights. Then - being careful not to move the rifle - aim with the scope. You will see how far off you are.

Scoping an M14 is an experience, can be painful, but the result is cool!

Best of luck!
 
pull the casm mount off and look closely at the machining of the sight pocket itself . the machining on my norc caused the casm mount to be misaligned. the problem will be apparent in the very front of the sight pocket

Yeahhhhhh.... We are going to need you to go ahead and take some pictures..... yeahhh.. and you know what, we are going to need you to go ahead and post them too...... Yeahhhh..... TPS report cover page.....
 
I'd just put the sights back in and use a quality tried and true arms 18. Seem to fit all my chinese rifles with zero issues every time ;)

Along the same lines :yingyang: , I had an AG-42B in .308 that simply "wouldn't seem to shoot straight" ;).....b/c there were 1-inch rings :) , I simply went to the hardware/lumber store, bought a long dowel that was 1-inch in diameter :evil: , and made sure that the dowel (when sitting in the scope rings) was exactly parallel to the barrel.....

Problem solved, so long as the rings and scope-mount stayed tight !
 
I bought this same scope mount for my norc m14 and i had the same problem. I don't however blame the product as it seemed very good quality. Just to get it even close to straight i had to do some major screwing around with the screws and it still was never straight. I think the pocket itself is bent.

In the end i just went back to open sights.
 
Yer playing with fire when you try and correct a receiver machining flaw in the scope mount pocket. The "floor" of the sight pocket is one of the thinnest areas of steel on the receiver. Any removal of material in there and your receiver should be re hardened. Long and short, for those with this issue, use a different mount.
 
Just got home ten minutes ago from my first time shooting my m14 with a brand new CASM mount with a busnell elite 10x40. Took about the usual 5 shots to sight in(bore sighted first). Ran 100 rounds thru it with no substantial loss in accuracy. I'm going to take a wager it's your scope. Your tasco's cherry and probably its internals have been popped ;)
