Never worked with plastic? stock before. Dropped a 721 action into a factory 700 stock. It lined up with mid-point front and back. Tang is about 0.1" proud of stock. If I inlet it deeper it wont line up with the mid-point. If I add more to the stock to bring it up to the tang what do I use that will stick? The PTG trigger guard is also a bit proud but I can probably inlet that deeper to no ill effects other than shaving down the magazine a bit.

Do the more recent 700 actions have a different radius or lower tang than the 721? Don't have a 700 to compare it to.

Thoughts? Thanks guys.

Might get more help in the Gunsmithing Forum just a few topics down...

This is gunsmithing.
Short answer is that they re the same. Your tang should not have a gap; look where it is hitting.
Trigger guard from PTG I know nothing about but I used a standard 700 bottom last time I built a 721.

If you use a bedding product you well have use a manual locks to hold it to the stock.

I recommend you find out why it is not sitting down on the stock like it should first.

The 721 magazine box is deeper than any M700 magazine boxes

Try the barreled receiver and guard by themselves

A few years ago I put a 721 in a DBM stock and converted the receiver rails to accept the DBM magazine

The 700 TupperWare stock requires material removal forward of the rear action screw hole.

'Tis the difference between a 700 w/ M.Walker trigger group inlet & a 700 X Mark trigger group inlet.

Material will also need to be removed aft of the bolt handle cut in the stock for the 721 safety lever.

use inletting black and inlet it to fit has worked for me.
