Internet auction sites that deal mainly in guns and ammo
popped up last spring after eBay, anticipating negative
publicity, stopped allowing gun sales.
For the most part, these are legit avenues, with nearly all
the guns listed coming from regular dealers with stores. As at
the (unfairly) oft-maligned gun shows, virtually all sales
require the Brady Bill background check and other federal
paperwork.
There is a loophole; guns made before 1898 are not considered
weapons, and aren't subject to federal firearms laws. For the
most part, that means little, since such guns were designed to
fire obsolete black powder cartridges, and most have an
extremely low rate of fire even if you can find the bullets
for them.
But now some nutball is driving a truck through the exception.
He's taken pre-1898 Mauser bolt-action infantry rifles (great
truckloads of which are no doubt available from China today as
they upgrade their military), cut them down into hunting rifle
form, and converted them to the relatively low-powered carbine
cartridge that the AK-47 fires. He is now (legally) selling
them over the Web, sans paperwork.
Put a 4X scope on one of these babies and you, too, can give
Oswald a run for his notoriety. Five shots as fast as you can
work the bolt. And it's untraceable.
Great, no doubt the Feds will soon crack down, to the
annoyance of harmless collectors. Jerk.
