If the barrels are classified as "sporting", then they can be imported with no problems.
USC & SL8 barrels are still very importable.... but there is no market for them & they are expensive.
416 barrels would have to be in a "post-ban" configuration to be imported... then they could thread them and add a lug.
You'd be better off bbuying POF or LMT, etc... The HK stamp means nothing to me, FWIW.
There is no incentive for H&K to even try to help out civies.... besides, the 416 falls under HK "Defense", so it will NEVER happen.
H&K would have been a great company if they hadn't fucked around for the past 30 years making "space" guns that no one ever bought. They spent millions on concept guns that were never made when they should have been building a fucking plant in the US, if for nothing,at least the investment of having a US plant. Hell, almost every other Euro gun maker has a plant here... or atleast an assembly plant
H&K will never be a big dog because they are stupid, business wise.
Fuck'm, bring on FN
