i was half wondering weather or not it would be more cost effective to go down to the us of a and pick up a complete ar15 upper reciver, than it would be to buy one here. has anyone done this already? (im sure somebody has), but is it more complicated than you would think it would be. ive seen forums on ar15.com saying that the usa requires import/export permets, but i cannot see why, the lower is 'the gun'. any info will be appreciated.




























...still with these questions?
