Actually, I'm looking for a M14 'taylor' to fit my M1A build into a Sage EBR stock. Can some one point me to an experienced smith? I'm dealing with a non-plug'n play scenario with my EBR stock.
 
never, ever, had to make any alterations to receiver or chassis on the top bearing surfaces.
I have however altered the front and rear bearing pads of the trigger groups to achieve proper tension without milling the 1000.00 sage chassis.
The M14Doc / M14Doctor , which is me, is retired from all things firearms related when it comes to business so sorry I can be of no help.

an explanation of the problem and perhaps I can walk you thru it.
No offense to notsorichguy, I'm sure he know his schit, but I've fit several dozen sage rigs, for both individuals and for professionals using them for work and always ended in success. from the early navy seal versions (grey with AR buttstock) to the newest models available in Canada and no modifications were made to fit the receivers. except for the trigger points I mention above.
but then again, there's a first time for everything so let's here some details if you can OP.

No offence taken whatsoever.

I have never had a SAGE Chassis on my bench, so I was only guessing on a possible fitment issue.
 
I had one of the very first Sage EBR stocks that came into Canada many years ago.

If you read the sticky posted titled:"Re-Barrelling the M-14 & Headspace Myths in Norc M14's ", I documented my sage EBR build.

I mentioned having to remove some material from the underside of the top hand guard because of the aftermarket barrel I used:

"Now the CrazyHorse barrel is a Medium weight NM contour and should fit in the Sage stock, but the top rail/handguard was hitting the barrel shoulder just in front of the op rod guide.I had to dremel away some material in order to get enough clearance for the rail/handguard.You have to be VERY careful as there is not a lot of material around one of the screw holes."

Other then this issue with this particular barrel, the Sage builds myself and GG&FB worked on never need any modification to the chassis or receiver.

I told you how to do the correct alterations.
and I can garauntee, I've installed more sage chassis for happy Canadian m14 nuts than anyone else in the country.
Some have even served over seas in private security contract detail with a group working ships in the gulf of Oman.

take the advice I took the time to type out and give to you by private message and work with it.
OR email cassey at tac ord and spend some cash getting a solid smith to do it for you.


edit to add:
the rifle, a heel stamped norinco , built by or sourced from a very highly reputable CGN who is stacked full of M14 knowledge. just to set the scene here.
You said in your message the heel of the receiver didn't look right.

M14 receivers are not flat at the back. look up the drawing of the rear of the receiver. it is has a arc to it starting just behind where the oprod notch is, all the way to the rear. it's slight and hard to spot, but it is there and that way for a reason, don't mess with it. Also , really only the very rear most portion of the U shape of the actual very rear of the heel, bears on the stock. So again, you don't need to modify your receiver or chassis at the heel. You do so at your own risk and have been advised. If you got that rifle from I<3M14s as you stated in the message to me, dollars to donuts, there's nothing wrong with that rifle as far as dimensions go.
anyhow, when the sage chassis just does not permit proper lockup or engagement of the trigger group there are generally 3 places you look to fit the parts to the chassis. the receiver legs, make sure they are not binding. stone or file the receiver legs in the appropriate location to allow the action to fully seat with the oprod guide block bolts installed but not snug or tightened at all.
then it's all trigger group. it bears on both side at the front, or "the wings" and it also bears at the tail end where the trigger guard locks in.
So, you either put the chassis in a milling machine and remove material from all those bearing locations and fit by trial and error
OR you do what I told you by private message so you don't ruin the value of the chassis.
work the 3 trigger bearing locations evenly with files/stones and use a caliper to ensure even and same amounts are removed from the bearing pads all around, until you achieve full trigger group lockup and the rifle consistantly and reliably passes the trigger function test.

that's it man. If you need and more help than that, email mr Ron Smith of smith enterprises, he has installed lots of sages to Chinese rifles too, and I guess LOTS more than I have

Thanks 45ACPKING for the info. I have a M305 trigger group to use as my first attempt. I don't want to mess up my USGI housing. I plan on doing the job this weekend.

The group is tilted. I can see wear marks on both the stock and group feet from improper angle. It was sitting on the 1/3 front portion of the feet only.

Thanks again.
