Over the next while I will be reposting & updating the M14 FAQ that was on the old site. Pics will also be added to clarify some modifactions.

USGI Fiberglass Stock Modifactions.
For all you new M304/M14 owners who are looking to swap the Chinese Mystery wood for a USGI fiberglass stock, here is how to do the following Modificaions:
1) Filling the selector cutout.
2) Building up the area for the recoil spring guide retaining pin. That's so it don't drift out on you under magazine pressure (when the mag is place.)
Filling the selector cutout.
The selector cutout will be filled in with JB Weld.it is important to make sure that the area to be filled is clean, and degreased.
Before Filling

NOTE: I now use Permatex 5 min. Cold Weld as I hated the waiting time for the regular type weld epoxy.
I first made up some cardboard shoring that had wax paper glued to one side, so that the JB Weld doesn't stick to the cardboard. Tape the "shoring" on either side of the cutout.Mix up roughly 2/3 rds of each JB Weld tube and mix thoroughly.Let the JB Weld sit for 20 to 30 minutes to set up, so that it won't leak and run all over when you fill the cutout. I filled the cutout level with the top of the stock.Smooth out the surface and let set overnight.
After Filling

I had some settling of the JB Weld, so to level off the cutout, I used some glazing putty.That is the red stuff you will see in the photos.


After the "goop" has cured, file/sand until level and contoured with the stock.
Norinco/Polytech Op Rod Spring Guide Retaining Pin Modifaction.
Now, you will want to build up a JB Weld "dam" where the retaining pin for the recoil spring guide is located.This is the area on the right side of the stock just at the front of the mag well.
Retaining Pin Area

Just as with the cutout,make sure the area is clean and degreased.
Before build Up

I have changed the way I do this modification. Instead of using the receiver to “shape” the area, I use cardboard and build a “dam” to contain the JB Weld.The cardboard is held inplace with masking tape.
I also build up the dip in that area of the stock (where the connector link should be in a real M14) to the same height as the rear part of the stock.
After Build up

Hungry Here: My picture of the popsicle stick (welfare method) of doing this modification. I even left the popsicle stick so that all of you can see it....
Built up area & non built up area

Fill the “dammed” void with the JB Weld and level it off. Clean up any spillage. Acetone is your friend.
Let cure overnight, or in the case of the 5 min. weld, at least a few hours.
Remove the cardboard and clean up the area with a file/emerycloth/Scotchbrite pad.
Fill any voids, etc with glazing putty and sand.
Five stocks after being filled

Here is a pic of the masking tape being used to make up a dam/retaining wall for the JB Weld to set up against....
Here are some pics of the selector cutout filling operation, but I used some High Density foam to take up the space and keep things light. In the past I used some pieces of balsa wood or doweling to fit into that space.
Have a look at the 'dam' made of masking tape! Real easy and cheap solution. Let this cure overnight before profiling with some sandpaper and a block of wood.
Here is the same job but from the pistol grip end of things. Don't dump too much JB Weld all at once. Sometimes I'll do this operation in stages over 3 days. Take your time, have fun, make mistakes!!
That is all there is to it.These are actually pretty easy modifications to do.After you finish, start painting!!!!
