80% lowers are big buisness for a reason,,everybody knows it,,and as long as everything stays the same,,,they'll be around for a long long time,,as for 80% lowers covered by ITAR...how can that be,,these things aren't even considered a firearm,,,anybody can buy one,,no license required,,a glorified paper weight,,,,and to these guys saying how DIFFICULT they are to finish,,have probably never done one,,,i have a ton of friends who have done these,,,no sweat,,easy,,,the latest ones are even better and easier to do,,none of them have ruined one yet,,,but i admit there are some people who have ruined some,,but generaly they are people who shouldn't be around powertools to begin with,,LOl..the funny thing is,,,how EXPENSIVE they are here in canada,,,these go anywhere from $50.00 to 100.00 in the US,,there is a nice polymer one with jig available in canada that looks pretty good,,and one of the poster here have a very nice upper/lower kit too,,,although not cheap,,,and not exactly 80% according to some who bought from them,,make sure of what you are buying BEFORE spending your money,
