Hi, (correct me if i am wrong)
If you are looking to buy an m16A1 Vn you are probubly short of money. If you are not looking to upgrade the gun then You should look at the m16a3fm at:
www.Wgcshop.com(i am from the U.S.A and am unaware of shipping issues to Canada) It is inexpensive but not tokyo marui so it may not be as reliable, but it comes with full metal construction. If you are looking to have A gun upgraded to fps above 370 i recomend Getting a CA(Classic army) M16A3 (Almost all CA guns can withstand heavy upgrades) Or a tokyo marui M16A2. :cheers:
