They are between $700-800 US, but I don't know if anybody is importing the actual Sage version.
Vltor makes a chassis for them too that might be available throught their reps here, maybe try One Shot Tactical.
Vltor's stock is not a chassis. It is a surplus usgi fiberglass stock, chop modded with an adapter bolted to it.
Sage, JAE and Troy manufacture aluminum chassis and all are legal in canada.
Sage - Del selins and bashaw sports come to mind as suppliers
JAE wolverine supplies
Troy- one shot tactical (?), or CQB services(?)
All three are hard to source most of the time due to availlabilty.
The marstar akm is a chassis but not made anymore, only availlable used - CGN EE
All of the above are excellent chassis systems.
Then in a short while, the Blackfeather is due to debut from canadian manufacturer M14.ca.
If yer after a true chassis system, you have increasing options.
There will also be a new chassis system for the M1A/M14s/M305 released from my shop soon, we are working on debuting in the second week of July
