Since Sage stocks are now available in Kanada I thought I would share this -
After building Sage (and AKM) chinese rifles I have found that many chinese receivers (and barrels) vary from milspec, (I even had one receiver stock mating surface curved {both sides !}, not flat !).
You may find your build ends up with the receiver to high off the stock, so when you clamp your trigger assembly you bend the barrel down from the op rod guide rearward. Accuracy sux.
The aggrevating factor is the Sage bottom allen screw in the op rod guide (a good idea if the barrelled action fits) that the AKM Sage clone does not have. No bottom screw on the AKM op rod guide allows the receiver and barrel to pivot and have receiver contact with the stock and no barrel flex when the trigger assembly is installed and the op rod guide stock screws are tightened.
For you new Sage installers with loose receiver fitting an easy solution is a heel shim of the appropriate thickness that allows heel contact and tight trigger assembly lockup.
The worst I've had to do is extra thick heel shims to get tight trigger assembly lock up, and no other receiver contact, but still good accuracy. (1 MOA)
Also - I have seen the same with AKM's but nowhere near as much. Most need minor receiver filing (the stock is correct the receiver not, so I alter the receiver)
In any case - if you have a cheese grater stock that shoots poorly try tuning heel shims, and shoot. Add thickness shoot add thickness shoot etc.
I have found very tight trigger assembly lock up shoots very well.
The more I see of Sage the more impressed I am with Kanadian AKM stocks (for Sino-Kanuck rifles ). I have had less tuning to do to make the AKM's shoot well with Chinese rifles .
The Sage may fare better with Springfields or Military M14's - but I have only done a very few of those and they were easy drop ins.
M14 guru's -
Laz, Thomas, Barney etc. - any thoughts ?
Did I have a disproportionate number of Friday night Monday morning M14's ?

) is that when adding shims.... with each install of a shim, check to ensure there is no hammer follow prior to firing
