Ok...

..I can't stand it any more...I have to pipe in.
You guys !!!!!
A newer M14 USGI FG stock does not need nor should it be bedded.
There were not designed to be bedded.
There is not a lot of material to play with on these stocks, if you have beefed it up like Hungry did a while back....maybe it might be an option.
A well worn out USGI stock could be skim bedded at best, under the trigger housing area and a little on the top. Do not do a FULL bedding on a USGI FG stock.....in the long term you will weaken it.
If you are concerned about accuaracy.....find some other issues with your rifles. I only read a few of the replies........but after building and bedding these rifles over the years I have never heard of any the 'old school' guys (Hungry, Mr*, BillC, Savage [these 4 have about 80 years combined M14 expertise]....SKBY or myself.....sorry for any that I missed) ever bedding a USGI FG
Smith Ent is shipping 'Crazy Horse' rifles to all branches of the US forces with unbedded 45 year old FG stocks and with Smith parts are getting Sub MOA results....I have built a few CH type Norcs and managed the same results.
NO BEDDING REQUIRED
Don't waste your time......now playing with a norc stock might be a benifit, NM stocks require bedding...
You will not find bedding data for a USGI stock.....for a reason.
So Bed these stocks
Macmillan
GI wood
GI NM wood
Any newly made wood
Do not bed these stocks
Sage or Milarm Aluminun stock
JAE-100
USGI FG
I stand firm on this post.....unless of course Lee Emerson

(aka Different) shoots me down.......
