Parting out a rifle from retail or milspec retail equivalent parts would cost more than M & P Sporter assuming that the Sporter is 600 in this equation and the ammo is 400. In addition, the selection of parts in Canada is a fraction of what it is in the US, the prices in Canada are typically 10 - 20% due to importing complications and mark-up and finally shipping is internally in the US is super cheap because of USPS while here most vendors charge $15 - $20. Now that may not seem like a lot, but it quickly adds up if you're making purchases from multiple vendors.
While the parts in the M & P Sporter aren't "match-grade" or "competition ready" they are completely sufficient for most use cases. In fact, I would go as far as to say the M & P Sporter is probably the best low end AR readily available in Canada.
If you're new to building ARs you'll need a vise, armourers wrench, barrel nut grease and maybe a new barrel nut if you damage the existing one while removing it.
In addition, you could always sell the M & P bare receiver set to recoup some of the costs and make it that much cheaper.
