I have to read very well the "politics" about taking stuff to there.
No, as we explained above, receivers are the part which is prohibited from import. You can bring barrels, rails/handguards, stocks, flash hiders and internals; however receivers (upper or lower depending on the model -- in your case, an M4, it's the lower) and silencers cannot be imported (unless its clear plastic).
Hence the advice to bring only upgrades and modifications and buy the gun in Canada and re-modify it.
If you attempt to import it there's a very strong chance it will be seized.
